293.7 GWh Planned Capacity + 100 GWh Orders! Sodium-Ion Battery Storage Enters Large-Scale Growth Phase

With abundant resources and long cycle life, complemented by distinctive strengths such as excellent low-temperature performance and outstanding rate capability, sodium-ion batteries are accelerating their penetration into scenarios including new energy storage, electric two-wheelers, start-stop batteries, commercial vehicle battery swapping and backup power. In 2026, the industry achieved key breakthroughs in capacity planning, signed orders and investment & financing, with large-scale application clearly accelerating.

Capacity Layout

1. Overall: 293.7 GWh of Planned Sodium-Ion Cell Capacity

According to incomplete statistics from the CNESA DataLink Global Energy Storage Database, as of July 2026, 34 enterprises across China have laid out 45 sodium-ion cell capacity bases in 20 provinces (autonomous regions and municipalities), with total planned capacity of 293.7 GWh. Of this, 25.2 GWh is already operational, accounting for about 8.6%, while capacity under construction and planned totals 268.5 GWh, about 91.4%. The industry as a whole is transitioning from demonstration application toward large-scale construction.

2. Regional Distribution: Eastern Coastal Areas Account for Nearly Half

From the perspective of regional distribution and construction progress, sodium-ion battery capacity is mainly laid out in central and eastern China, with Fujian, Jiangsu, Sichuan, Qinghai, Anhui and Guangdong among the top provinces by planned scale. Leveraging a mature lithium battery industrial base, eastern coastal regions were the first to form clusters, accounting for nearly half of national capacity. The western regions, benefiting from abundant new energy resources and lower electricity costs, are accelerating their layout and becoming an important source of new capacity. Overall, sodium-ion battery capacity is highly concentrated in lithium battery industrial clusters, while gradually extending toward new-energy-rich and low-temperature regions in the west.

3. Enterprise Distribution: Three Types of Investors Competing

From the perspective of enterprise composition, there are mainly three types of investors in sodium-ion batteries:

First, lithium battery companies such as CATL, BYD, EVE Energy, Gotion High-tech and Great Power. Relying on mature lithium battery production lines, well-established supply chains and stable downstream customer channels, these companies are rapidly extending into the sodium-ion field. Their production lines are highly compatible with the lithium battery system, enabling flexible production switching according to market orders. With outstanding mass production capability, delivery stability and cost advantages at scale, they are the core players that first achieved GWh-level deliveries in the industry.

Second, emerging and start-up companies such as HiNa Battery, Zoolnasm, Jinna Technology and Namei Technology, whose core business is sodium-ion batteries. Most originate from technology incubation at universities and research institutes, with core strengths in deep technological accumulation and focus on niche tracks. Backed by specialized technical advantages, they deliver projects quickly and demonstrate notable lean operations.

Third, materials and cross-sector companies such as Do-Fluoride, Jiana Energy, Na Innovation Energy and Tongxing Environmental Protection. Building on their foundations in the materials segment, these companies build their own cell production bases along an integrated materials-to-cells path. Their core advantage lies in strong industrial chain synergy: they can locally supply their own sodium-ion battery materials, verify and optimize material systems while iterating product technology, and efficiently connect with downstream application scenarios, creating differentiated integrated competitiveness.

4. Technology Route Distribution: Polyanion Accounts for Over 70%

From the perspective of cathode technology routes, sodium-ion batteries fall into three main categories: the polyanion route has 23 bases with planned capacity of 212.5 GWh, accounting for 72.4%; the layered oxide route has 10 bases with planned capacity of 30.2 GWh, 10.3%; the dual route (layered oxide + polyanion) has 10 bases with planned capacity of 42.5 GWh, 14.5%; and the Prussian blue category has 2 bases with planned capacity of 8.5 GWh, 2.9%. Measured by operational and under-construction capacity, polyanion accounts for 49.6% and 74.5% respectively, ranking first in both; layered oxide accounts for 32.5% of operational capacity but only 8.2% of under-construction/planned capacity.

Figure 2 | Cell capacity and number of bases by technology route

Source: CNESA Global Energy Storage Database

The differences in capacity layout between the layered oxide and polyanion routes mainly stem from differences in material performance, application scenarios and industrialization conditions.

Polyanion cathodes feature stable structures and long cycle life, with abundant main raw materials. Some of their production processes are similar to those of the LFP system, offering relatively clear paths for capacity expansion and cost reduction. They suit scenarios sensitive to lifetime and cost but less sensitive to volume, such as utility-scale storage, backup power, start-stop systems and two-wheelers.

Layered oxides hold advantages in energy density and rate performance, but their cycle life still needs improvement and their cost needs to fall, suiting scenarios with high energy and power demands. Sodium batteries have already achieved scale application in start-stop batteries, and future incremental demand will be dominated by energy storage. As polyanion shows significant advantages across diverse application scenarios, enterprises concentrate their expansion on the polyanion route, while layered oxide focuses on differentiated power applications. In addition, 11 bases adopt a dual-route layout of layered oxide and polyanion to cover both storage and power scenarios; the Prussian blue route remains in the early industrialization stage with no operational capacity yet.

Sodium-ion Battery Orders: Over 100 GWh of Global Storage Orders Signed

In H1 2026, domestic sodium-ion battery orders officially moved from the demonstration phase into the commercial scale-up phase, with steady growth in industry production and sales.

CATL and HyperStrong reached a three-year 60 GWh strategic cooperation order for energy storage sodium-ion batteries, setting a global record for a single sodium-ion battery order.

According to statistics, energy storage applications will be the largest source of future sodium battery orders, accounting for 40%. Eight storage tenders were awarded during the year, totaling 170 MW / 512 MWh, with sodium-ion batteries entering the utility-scale storage market mainly through mixed LFP-plus-sodium configurations. In addition, sodium-ion batteries achieved commercial deployment in multiple scenarios: the China Tower Tibet telecom backup power project was awarded to Veken and Shuangdeng, and the telecom backup power and new energy heavy truck markets continue to open up.

In overseas markets, according to incomplete statistics from the CNESA DataLink Global Energy Storage Database, as of July 2026, overseas sodium-ion battery storage orders were signed in a concentrated manner, with commercialization clearly accelerating.

Overseas local manufacturer Alsym Energy has successively signed 8.5 GWh and 9.0 GWh sodium battery storage projects, and Peak Energy has secured a 4.5 GWh storage order, focusing on the US commercial & industrial and utility-scale storage markets. Chinese companies have also made breakthroughs overseas: CATL signed 5 GWh and 2 GWh sodium battery storage cooperation projects with European integrator Alfen and Eastern European energy company Solarpro respectively; on September 2, HiNa Battery signed a five-year 10 GWh long-term sodium battery supply agreement with Korea's VOLTA Corporation.

In terms of order characteristics, new sodium battery orders are currently highly concentrated in the storage segment, and most large projects are medium- to long-term framework cooperation agreements rather than orders for immediate delivery. The actual delivery pace is constrained by multiple factors, including capacity ramp-up, grid connection certification and policy subsidy implementation.

Investment and Financing

Early-Stage Financing Accounts for Over 60%

In H1 2026, China's sodium-ion battery financing market showed distinct stage characteristics: early-stage financing, including angel, Series A and Series B rounds, accounted for more than 60%, with Series A companies the most concentrated and industry entry enthusiasm running high, while only a very few companies completed mature-stage financing.

In terms of financing segments, cell production lines and cathode/anode materials are the core areas, with upstream material financing rising sharply. It can be judged that material scale-up is currently the most critical factor driving sodium-ion battery cost reduction.

In terms of investors, funding sources show a diversified pattern, with industrial capital, local state-owned capital, market-oriented venture capital and overseas capital coordinating their deployment.

In terms of track layout, investment and financing cover the entire sodium-ion battery industry chain, with the three core segments of cathodes, anodes and cells seeing the most concentrated financing.

In terms of technology preference, capital investment closely follows the industry's technology convergence trend, with polyanion cathodes and hard carbon anodes as the mainstream layout directions, alongside diversified technology reserves.

Note: The English names of companies and investors in the table are tentative transliterations; please replace them with official registered names where available.

Industry Outlook

Overall, China's sodium-ion battery industry has left the technical validation stage and entered a key window of development from technology deployment to scale ramp-up. Over the next 2-3 years, with steadily rising capacity utilization, continuously falling core material costs and expanding application scenarios, the industry is expected to bid farewell to the early planning phase and fully enter a new stage of efficient implementation and effective output. Going forward, sodium-ion batteries are expected to continuously replace lead-acid batteries in scenarios such as new energy storage, light-duty power and backup power, while gradually penetrating parts of the lithium battery application market, truly crossing the threshold of large-scale growth and achieving stable commercial, scaled development.

How to Sell Energy Storage Systems into AIDC? Understand the White, Gray, and Black Zones First

Demand for energy storage in AIDC (AI data centers) is shifting from “whether to install” to “where to install it and what problem it solves.”

At the roundtable “Storage-Computing Convergence: Technical and Commercial Practices of Power-Computing Coordination for Data Centers in the Era of Large Models” at the recently held 11th Western Energy Storage Forum, front-line speakers from data center operators and energy storage companies pointed out that, from the campus-level energy foundation to the rack side close to GPUs, different time scales correspond to completely different storage technology routes, and no single product fits all scenarios.

The forum was hosted by the China Energy Research Society, Lanzhou University, and the China Energy Storage Alliance (CNESA). Tang Liang, Deputy Secretary-General of CNESA, moderated the dialogue, joined by Chen Shengjun, Senior Vice President of Chindata Group; Qi Yebai, Senior Vice President and Head of Energy Planning of VNET Group; Ma Jiaxin, Director of Energy Storage Solutions of Shuangdeng Group; and Zhang Kexin, Senior Manager of Policy Research of HyperStrong.

Value Ranking of Energy Storage in AIDC

Deploying energy storage in AIDC must follow the basic logic of “demand driving technology and product selection.” In other words, storage at different levels must first answer what the user’s real pain points are, rather than discussing how much revenue it can bring.

Chen Shengjun, Senior Vice President of Chindata Group, divides the value of energy storage into four levels.

The first is CAPEX (capital expenditure) — whether upfront development and O&M costs can be reduced. If a suitable storage and power supply scheme can cut related capital input, its value first shows at the initial investment stage.

The second is avoiding SLA penalties. For critical business, the value of a stable power supply far exceeds electricity price differentials. Once supply continuity is affected, penalties faced by a data center can reach hundreds of millions of yuan.

The third is reducing OPEX (operating expenditure), including daily operating costs such as electricity bills.

Only the fourth is the additional revenue gained from deploying storage. Chen stressed that simply emphasizing “how much money storage can make for me” is not the first concern of data center owners.

Qi Yebai, Senior Vice President and Head of Energy Planning of VNET Group, also said that the necessity of storage entering AIDC can be summarized in two points: first, making a real contribution to the power supply by providing power support, instantaneous supply, and reliability assurance; second, gaining verified economics. At present, however, the electricity costs saved by storage through peak-valley arbitrage and demand management account for at most 5%–10% of total OPEX — a value mismatch compared with the hundreds of billions of yuan of computing assets that need protection. The value of storage should therefore be measured not by “how much electricity was saved” but by “how much assets were safeguarded.”

Technology Routes of AIDC Energy Storage

For AIDC loads, the core of storage technology routes lies not in one battery type covering everything, but in matching capabilities across different zones and time scales. Chen Shengjun summarizes this as differentiated configuration across the white zone, gray zone, and black zone.

White Zone: Second- and Millisecond-Level Response to Power Transients

The “white zone” refers to the computer room area housing IT equipment — where server cabinets actually compute and power is directly supplied to computing — and also to the low-voltage supply area from inside the cabinet down to the chip level (generally within 48V). It is where power consumption of the entire data center is most concentrated and most volatile. During AI training, GPU load can jump from idle to full load within milliseconds, easily causing voltage sag or false triggering of overload protection.

The “white zone” therefore emphasizes power-type storage with second- or even millisecond-level response, aiming mainly to stabilize power fluctuations, suppress peaks, and reduce demand charges. To meet this need, technologies such as capacitors, supercapacitors, and high-rate lithium batteries in BBUs are more targeted.

Gray Zone: Minutes to Hours, Driving SST and High-Rate Battery Demand

The “gray zone” refers to the area housing back-end infrastructure such as electrical and mechanical equipment, providing power supply, cooling, and other supporting functions. As cabinet power density rises, supply voltage is being upgraded from traditional AC to 800V or even higher-voltage DC to reduce line losses. SST (solid-state transformer) is seen as the key technology for gray-zone transformation: it can step down voltage directly from the high-voltage grid and output high-voltage DC matching the cabinets, simplifying the gray-zone structure and achieving AC/DC compatibility.

Compared with the white zone, the gray zone operates on longer time scales, typically from minutes up to an hour. Lead-acid batteries in traditional UPS will not be fully replaced in the short term, but options such as sodium-ion, high-rate LFP, and supercapacitors are entering retrofits and comparisons. For scenarios converting general-purpose computing rooms into intelligent computing rooms, adding high-power compensation in the gray zone is also a technology path suited to local conditions.

Black Zone: Long-Duration Storage Demand Emerges

The “black zone” refers to the connection point between the bulk grid and the behind-the-meter microgrid, covering utility access, transformers, storage, backup power, and microgrid dispatch — a critical area for ensuring supply continuity and power-computing coordination. Closer to the high-voltage side and the power source side, the black zone can also be planned in a unified way with direct green power connections. Here, long-duration storage can serve as the energy foundation and long-term backup, with demand for 6-hour, 8-hour, and even longer durations becoming evident. For scenarios combining a high share of renewables with a high share of power-electronic loads, grid-forming storage can provide regulation capability and reduce major losses from risks such as wideband oscillation.

Solution Selection for AIDC Energy Storage

Qi Yebai believes that for data centers, different technology routes suit different risk types. Meanwhile, technology routes should not be viewed statically: technology is advancing and customer awareness is changing too.

Qi also pointed out that campus-type wholesale IDC and urban retail IDC follow different logic: for the former, large customers come first and the campus is built afterwards, with customers directly setting the technical standards; for the latter, the computer room is built first and customers are found later. Since a single project of a large customer can reach hundreds of megawatts, storage solutions must be highly customized and cannot be configured along the standardized product logic of traditional utility-scale storage.

Zhang Kexin of HyperStrong noted that on the AIDC computer-room side, HyperStrong is also developing solid-state transformer (SST) products, with releases planned before the end of this year. On the energy foundation side, where wider power access and system regulation must be considered, HyperStrong proposes a “lithium-sodium synergy” approach: sodium-ion batteries handle short-duration shocks, fluctuations, and switching, while lithium-ion batteries handle longer-duration regulation and peak shaving — matching AIDC’s multi-timescale needs through a division of labor between different electrochemical systems.

Ma Jiaxin, Director of Energy Storage Solutions of Shuangdeng Group Co., Ltd., said that AIDC customers’ customization needs are completely different, with a “disruptive” impact on storage products, especially in the North American market. On one hand, cells must withstand short-duration, high-frequency, high-current discharge while also meeting long-duration operation and lifetime requirements; on the other, AIDC’s requirement for SOH (state of health) estimation accuracy may rise from the industry-common 5%–6% to 2%–3%.

Moreover, the integration of backup power and energy storage means control strategies cannot remain static: as battery capacity degrades, the system must dynamically adjust the capacity allocated to backup versus economic operation according to SOH, and thermal management strategies differ under different operating conditions. For PCS, grid-following, grid-forming, off-grid operation, and smooth switching capabilities are required.

AIDC Energy Storage Market Size

Zhang Kexin of HyperStrong looked ahead to future development models. Today’s mainstream power-computing coordination is a one-way, downstream-to-upstream demand model: computing companies demand from AIDC, and AIDC demands from the power supply. In the future it may evolve into two-way regulation between computing and power, as AIDC advances from traditional cabinet rental and server rental models into a “Token factory,” requiring more adjustable resources and giving energy storage much larger room to play.

Ma Jiaxin believes AIDC energy storage is about to enter an explosive growth period — but only after market acceptance, demonstration projects, and testing and certification of new products all run smoothly, after which development will accelerate rapidly. At the same time, overseas policy risks deserve attention: recent US bans targeting energy storage systems and related equipment will have some impact on Chinese companies entering the North American market.

Qi Yebai of VNET Group raised a neglected incremental scenario. He believes storage vendors’ thinking should not just circle between the two ends of “macro (source side)” and “micro (inside the computer room)”; in between lies a “mesoscopic” level: can Phase I and Phase II of the same customer be bridged? Can adjacent data centers be linked, using storage for DC transfer? Viewed from a broader perspective, some more differentiated value points can actually be matched. He encouraged companies to break out of inertial thinking and actively explore.

Chen Shengjun of Chindata Group stressed that next year is critical. Whether storage companies can deliver truly valuable products for data centers in 2027 will determine how large the storage market in the AIDC track can grow and how far it can go. Chen also revealed that from the end of this year into next year, new electrical architectures will be released one after another, and storage may be embedded within them.

The 15th Energy Storage International Conference and Expo (ESIE 2027) will be held on March 16–19, 2027 at the Beijing Capital International Convention and Exhibition Center. For the first time, the expo will feature an AIDC Energy Storage section, showcasing the complete AIDC storage industry chain, from high-rate cells, BBU backup power, UPS, and HVDC to solid-state transformers (SST) and complete system solutions.

China’s three major telecom operators, cloud service providers such as Tencent Cloud, third-party IDC operators such as Chindata and VNET, and leading overseas computing and cloud companies such as Amazon, Google, and Meta will gather at the event to share their on-the-ground practices in data center energy storage.

The expo will also set up an AIDC Energy Storage New Product Launch Zone, supporting companies to debut innovative products and technical solutions in the AIDC storage field. Whether entering the new AIDC storage track, launching annual innovative products, or connecting with upstream and downstream partners across the industry chain, ESIE 2027 is the industry’s key matchmaking platform.

How Is AIDC Energy Storage Different from Utility-Scale and C&I Storage?

As AIDC (AI data centers) gradually become a key application scenario for energy storage, a sharp contradiction has surfaced: does the storage logic designed for power systems fit the power consumption characteristics of computing centers?

At the “Storage-Computing Integration” roundtable of the Computing-Electricity Synergy Sub-forum at the 11th Energy Storage Western Forum, frontline guests from data center operators and energy storage companies pointed out that AIDC energy storage must shift from the logic of utility-scale storage to the logic of critical infrastructure.

The forum was hosted by the China Energy Research Society, Lanzhou University and the China Energy Storage Alliance (CNESA). The dialogue was moderated by Tang Liang, Deputy Secretary-General of CNESA, with Chen Shengjun, Senior Vice President of Chindata Group; Qi Yebai, Senior Vice President and Head of Energy Planning of VNET Group (21Vianet); Ma Jiaxin, Director of Energy Storage Solutions of Shuangdeng Group; and Zhang Kexin, Senior Manager of Policy Research of HyperStrong.

How Are AIDC’s Ultra-Large DC Loads Changing the Power System?

At this year’s National Two Sessions, computing-electricity synergy was written into the Report on the Work of the Government for the first time and explicitly listed as a new infrastructure program, elevating it from industry exploration to a national strategy.

AIDC is becoming a major electricity consumer on the grid: over the next five years, its newly added annual electricity consumption will reach 100 billion kWh, equivalent to the annual output of the Three Gorges Hydropower Station. Qi Yebai, Senior Vice President and Head of Energy Planning of VNET Group (21Vianet), noted that AI brings not only growth in total electricity consumption but, more importantly, a change in load structure.

Qi Yebai, Senior Vice President and Head of Energy Planning, VNET Group

It is understood that China’s power supply and load are currently dominated by the AC grid, but AIDC represents an ultra-large DC load that constantly switches between communication and computing, with the drawback of poor adjustability. This means computing centers cannot be treated as ordinary industrial loads.

In terms of development, Qi Yebai divides computing-electricity synergy into three phases: the parasitic phase, the symbiotic phase and the regenerative phase. In the early stage, the computing side proactively adapts to power conditions, typically locating in regions with advantages in electricity prices, supply capacity or green power resources. In the middle stage, power and computing begin to exchange information and collaborate on dispatch, load forecasting and operations. The longer-term goal of computing-electricity synergy is for the two systems to perceive each other’s state and participate in more refined energy optimization while safeguarding computing services — with energy storage playing a key connecting role throughout this process.

AIDC Projects’ Landing: Power Availability Alone is Not Enough

From the perspective of AIDC project deployment, China has two models: “build after securing customers” and “build first, find customers later.” How should the two models be viewed? This is a hot topic in the industry today.

Chen Shengjun, Senior Vice President, Chindata Group

Chen Shengjun, Senior Vice President of Chindata Group, pointed out that computing center construction requires comprehensive consideration of factors such as chips, land, electricity and water, and that no matter how fast demand grows, grid connection remains the precondition. Without power, large-scale construction is simply out of the question.

According to Chen Shengjun, premium nodes are also areas of concentrated load: they offer good network conditions and strong business demand, but grid connection capacity is tighter. Regions with better renewable resources may fall short on networks, industrial support or construction conditions. Therefore, computing center siting cannot consider electricity prices or total energy alone; it must strike a comprehensive balance among chips, land, electricity and water.

In the short term, projects need to resolve reliable grid access and construction sequencing; in the long term, green power procurement, supply reliability and economics must all be incorporated into planning.

New Requirements AIDC Load Characteristics Place on Energy Storage

Faced with AIDC as a brand-new application scenario, the role and development logic of energy storage are changing.

The positioning of energy storage has changed. As Ma Jiaxin, Director of Energy Storage Solutions of Shuangdeng Group Co., Ltd., put it: “Energy storage is now closer to the infrastructure of computing centers — the product design logic, service model and system positioning have all changed.” In power systems, energy storage appears as a regulating resource, with the core tasks of peak shaving and valley filling, dispatch participation or improving renewable energy consumption. In AIDC scenarios, storage must first serve the continuous power supply and power quality assurance of high-value loads, and its system value can no longer be measured by single-cycle charging and discharging revenue alone. Under these new characteristics, energy storage in computing centers must participate in energy optimization while also providing support during power fluctuations, short-term disturbances and even emergency scenarios.

Ma Jiaxin, Director of Energy Storage Solutions, Shuangdeng Group Co., Ltd.

Operating conditions have changed. Ma Jiaxin noted that grid energy storage products are typically defined by 2-hour, 4-hour or even longer durations, and their operation approximates low-frequency, periodic dispatch scenarios. AIDC energy storage, however, cannot simply wait for one charge-discharge opportunity per day: it may need to respond to power disturbances at millisecond speeds, balancing multiple objectives — backup, power assurance, green power utilization and economic operation — while smoothing load variations. This means storage system design can no longer stop at a “capacity + duration” configuration approach, but must build coordinated capabilities spanning cells, BMS, PCS, PMS and EMS.

Customers and delivery models have changed. Grid storage customers are mostly renewable power plants, power generation groups or grid-related entities with relatively mature and standardized needs, while computing center end customers are diverse — ranging from technology companies to managed service providers — and impose different requirements on vendors.

Zhang Kexin, Senior Manager of Policy Research at Beijing HyperStrong Technology Co., Ltd., believes that storage applications in computing center scenarios must first clarify which side they are positioned on — campus-level and machine-room scenarios call for different overall storage design schemes. For campus-level AIDC with storage, the role of storage remains energy regulation: smoothing peaks and valleys and reducing comprehensive electricity prices, in which the advantages of traditional source-grid-side storage products can carry over. On the machine-room side, storage applications need new design approaches, such as coupling with sodium-ion batteries.

Zhang Kexin, Senior Manager of Policy Research, Beijing HyperStrong Technology Co., Ltd.

Conclusion

This roundtable clearly reveals that computing centers are bringing energy storage into a new application scenario. Faced with computing loads that are high-density, high-frequency, poorly adjustable and extremely sensitive to supply continuity, the value of energy storage will increasingly lie in system reliability, fast response, green power coordination and refined operations.

For the storage industry, this is both a new incremental market and an upgrade of capabilities. Future competition will not be limited to battery capacity or equipment prices, but will hinge on whether players understand the power consumption logic of computing businesses and can turn energy storage into dispatchable, verifiable and long-term operable power supply capability.

The 15th Energy Storage International Conference and Expo (ESIE 2027) will be held on March 16-19, 2027, at the Beijing Capital International Exhibition & Convention Center (CIECC). For the first time, the event will feature an AIDC energy storage section showcasing the complete AIDC storage industry chain, from high-rate cells, BBU backup power, UPS and HVDC to solid-state transformers (SST) and integrated system solutions.

China’s three major telecom operators, cloud service providers such as Tencent Cloud, third-party IDC operators such as Chindata Group and VNET Group (21Vianet), and leading overseas computing and cloud companies such as Amazon, Google and Meta will gather at the event to share data center storage deployment practices.

The expo will also set up an AIDC energy storage new product launch zone, supporting companies to debut innovative products and technical solutions in the AIDC storage field. Whether expanding into the new AIDC storage track, launching annual innovative products, or connecting with upstream and downstream industry chain resources, ESIE 2027 is a key platform for the industry.

**Chairman of CNESA; Director of the Institute of Engineering Thermophysics, Chinese Academy of Sciences**

Chen Haisheng stated that 2026 marks a critical year for China’s new energy storage industry as it transitions from large-scale expansion toward high-quality growth.

By the end of June 2026, China’s cumulative installed capacity of energy storage projects reached 237.2GW, representing year-on-year growth of 41.4%. Among this, new energy storage accounted for 168.2GW, exceeding 70% of total capacity. Newly installed capacity reached 21.64GW/58.20GWh, while storage duration continued to increase and technology pathways rapidly evolved.

Despite rapid industry expansion, safety challenges remain the most critical issue facing the sector. Chen emphasized that CNESA will continue strengthening international cooperation, building a global energy storage safety platform, developing comprehensive safety systems, and supporting the global transition toward green and low-carbon energy.

Emerging Insights: Tackling Energy Storage Safety Challenges Across the Entire Value Chain

A clear trend is emerging: energy storage safety innovation is moving beyond battery cell-level protection toward a comprehensive approach integrating battery innovation, system architecture, intelligent operation and maintenance, safety standards, and application scenarios.

Sun Jinhua
**Academician of the European Academy of Sciences; Professor, University of Science and Technology of China**

In his presentation titled “Fire Risks and Prevention Strategies for Energy Storage in Computing Power and Data Centers,” Sun Jinhua highlighted the rapid growth of electricity demand from artificial intelligence computing and data centers.

Electricity consumption by computing and data centers approached 200 billion kWh in 2025 and is expected to reach 526–700 billion kWh by 2030. With China requiring newly built data centers in national computing hubs to achieve at least 80% renewable electricity consumption, energy storage will become increasingly essential.

However, fire risks remain a major concern. Global energy storage fire probability is estimated at approximately 0.3%–0.4%, while data centers face higher potential losses due to concentrated assets and personnel, requiring much stricter safety standards.

Sun proposed three layers of safety protection:

Improving intrinsic battery safety through interdisciplinary research and AI technologies to reduce thermal runaway probability below 10⁻⁸;
Enhancing process safety through intelligent thermal management materials, fiber-optic in-situ monitoring, and integrated thermal management and early-warning technologies;
Optimizing firefighting solutions through technologies such as liquid nitrogen extinguishing and multiple-stage suppression.

He emphasized the need to develop intelligent safety management platforms integrating remote monitoring, predictive analysis, multi-level warnings, and dynamic response capabilities.

**Chen Zhongwei, Fellow of the Royal Society of Canada and the Canadian Academy of Engineering; Researcher and PhD Supervisor at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences.**

Chen Zhongwei delivered a keynote speech titled “Building an Intelligent Management System for the Full Life Cycle of Electrochemical Energy Storage.”

He identified five major challenges in the energy storage industry: design, manufacturing, management, operation and maintenance, and electricity market participation. AI-based full life-cycle management provides a key solution.

Since 2015, Chen’s team has focused on integrating electrochemistry and artificial intelligence, achieving breakthroughs in:

Building battery industrial databases covering design, manufacturing, management, and operation;
Developing AI-assisted battery design based on electrochemical simulation;
Creating electrochemistry-AI coupled models for battery health evaluation;
Establishing closed-loop manufacturing optimization through production data and performance feedback;
Applying AI algorithms and robotics for retired battery sorting and second-life utilization;
Developing high-precision algorithms for RUL, SOC, and SOH estimation.

Based on these technologies, the team developed the Energy Storage AI Intelligent Monitoring System, establishing a three-level health diagnosis framework covering cells, battery containers, and entire energy storage stations.

Yang Quanhong
**Chair Professor, Tianjin University**

Yang Quanhong discussed “Water Management in Intrinsically Safe Aqueous Zinc Batteries: Fundamental Principles and Solutions.”

He emphasized that future energy storage technologies must achieve high safety, low cost, and resource sustainability. Aqueous zinc batteries represent a promising pathway due to their intrinsic safety and resource availability.

However, commercialization faces challenges caused by water-related reactions, including hydrogen evolution, corrosion, dendrite growth, cathode structural degradation, and limited cycle life.

The key solution lies in precise “water management,” including:

Water reaction management;
Water demand management;
Water state management;
Advanced conversion-type cathode technologies.

Zhuo Ping
**Director, Fourth Research Division, Tianjin Fire Research Institute, Ministry of Emergency Management**

Zhuo Ping introduced China-led international standards research on energy storage fire safety.

She explained that energy storage fire scenarios should consider four major safety objectives:

Life safety;
Property protection;
Environmental protection;
Cultural heritage protection.

Fire scenarios should incorporate different application characteristics, ignition sources, fire types, firefighting systems, and human behaviors.

Zhang Peidao
**Solution Director, Energy Storage Business Division, Gotion High-tech**

Zhang Peidao shared industrial practices under the theme “Architectural Innovation of Energy Storage Systems in New Power Systems.”

He noted that energy storage faces challenges including efficiency improvement, safety risks, high availability requirements, and life-cycle cost optimization.

Gotion High-tech addresses these challenges through architectural innovation:

The Qianyuan Intelligent Energy Storage 2.0 grid-forming high-voltage cascade storage system directly connects to 6–35kV grids without transformers;
System efficiency exceeds 92%;
AI-based predictive maintenance improves operational efficiency by 50%;
Multi-dimensional sensing and fire protection systems create layered safety protection;
Modular design reduces land occupation by 38%.

The solutions have already been applied in projects including user-side storage in Jinzhai and grid-side storage in Lujiang.

Roundtable Discussion: AI Empowering Energy Storage Safety from Passive Protection to Active Intelligence

The roundtable focused on how AI can transform energy storage safety from passive prevention to proactive intelligence.

Hosted by Wang Qingsong, Researcher at the University of Science and Technology of China and Chairman of the CNESA Energy Storage Safety Committee, the discussion gathered experts from grid operators, equipment manufacturers, industrial software providers, sensor companies, and AI technology companies.

Participants agreed on three major conclusions:

The transition from passive protection to active intelligence is inevitable.
AI will not replace intrinsic battery safety, hardware protection, or human operation, but will serve as an enabling technology connecting sensing, simulation, and decision-making.
AI adoption should follow a gradual human-machine collaboration approach.
Challenges remain, including data silos, limited algorithm generalization, incomplete standards, and hardware adaptation issues.
Full industrial collaboration is essential.
Energy storage intelligent safety requires cooperation among grid operators, battery manufacturers, research institutions, software companies, and sensor providers.

Bookmark This! Six Long-Duration Energy Storage Technology Pathways, Three Revenue Models, and Prospects for Large-Scale Deployment

With multiple supportive policies being introduced, long-duration energy storage (LDES) is entering a period of significant growth opportunities!

Recently, the State Council of China issued the “15th Five-Year Plan Carbon Peak Action Plan”, while the National Energy Administration released the “Energy Sector Energy Conservation and Carbon Reduction Action Plan (2026–2028)”. Both policy documents explicitly emphasized the development of long-duration energy storage, indicating that LDES is gradually becoming an essential component of the new power system.

Currently, LDES technologies are developing toward greater diversification. Technologies such as compressed air energy storage (CAES), flow batteries, and hydrogen energy storage each demonstrate different advantages and limitations in terms of technology maturity, application scenarios, and construction costs.

This article provides a systematic analysis of LDES from three perspectives: technology development, revenue structures, and prospects for large-scale deployment, offering industry insights and references.

Six Technology Pathways Leading LDES Development for Diverse Applications

Long-duration energy storage technologies are diverse and mainly include:

Physical energy storage technologies, represented by pumped hydro storage, compressed air energy storage, and gravity energy storage;
Electrochemical energy storage technologies, represented by flow batteries and metal-air batteries;
Thermal energy storage (including cooling storage) and chemical energy storage technologies, represented by hydrogen energy storage.

Among them, pumped hydro storage is currently the most mature and widely deployed long-duration energy storage technology.

As of the first quarter of 2026, China’s operational pumped hydro storage capacity had reached 67.09 GW.

At present, pumped hydro storage is primarily based on large-scale fixed-speed pumped hydro power stations. However, as suitable sites for large-scale pumped hydro projects become increasingly limited, the development of small- and medium-scale pumped hydro storage projects is gradually increasing.

Gravity Energy Storage

The operating principle of gravity energy storage is similar to pumped hydro storage. It mainly uses the physical lifting and lowering of solid masses to drive power generation equipment, thereby achieving energy storage and discharge.

Currently, China’s 100 MWh-scale gravity energy storage tower demonstration project has been completed in Rudong, Jiangsu Province, and has entered the grid connection commissioning stage.

The project, invested and developed by China Tianying, has an energy storage capacity of 100 MWh and a power output of 25–26 MW. It is expected to be connected to the grid and begin operation by the end of 2026.

Compressed Air Energy Storage

Compressed air energy storage is another long-duration energy storage technology with significant potential for large-scale application.

The technology converts electricity from off-peak periods or curtailed renewable energy into compressed air pressure energy and thermal energy, storing them separately in air storage units and thermal storage units.

During periods of high electricity demand, the stored high-pressure air is released and expanded through turbines to generate electricity.

Currently, large-scale engineering applications mainly focus on adiabatic compressed air energy storage systems with thermal storage.

According to statistics from the China Energy Storage Alliance (CNESA), as of the first quarter of 2026, China had 14 operational compressed air energy storage projects connected to the grid, with a cumulative installed capacity exceeding 1.5 GW.

The total installed capacity of projects under construction and in the planning stage has exceeded 54 GW.

Flow Batteries

Flow batteries are electrochemical batteries in which the active materials of both the positive and negative electrodes are liquid.

Depending on the types of active electrode materials, flow batteries can be categorized into:

Vanadium redox flow batteries (VRFBs);
Zinc-bromine flow batteries;
Iron-chromium flow batteries;
and other technology pathways.

Overall, flow batteries offer advantages including:

high safety;
no risk of explosion or fire;
long service life;
deep charge and discharge capability;
and environmental friendliness.

By the end of 2025, China’s 10 kW-scale vanadium redox flow battery demonstration projects had already entered operation.

Thermal Energy Storage

Thermal energy storage refers to storing energy from sources such as:

solar thermal energy;
geothermal energy;
industrial waste heat;
low-grade waste heat;

and releasing it when needed, thereby addressing mismatches between thermal energy supply and demand caused by differences in time, location, or energy intensity.

Based on storage principles, thermal energy storage technologies can be categorized into three types:

sensible heat storage;
latent heat storage;
thermochemical energy storage.

Currently, relatively mature thermal storage materials include:

hot water;
molten salt;
refractory bricks;
and other thermal storage media.

Hydrogen Energy Storage

Hydrogen energy storage is a form of chemical energy storage that enables:

large-scale energy storage;
long-duration storage;
and cross-regional energy storage.

It mainly consists of three key stages:

hydrogen production;
hydrogen storage and transportation;
hydrogen utilization.

Water electrolysis for hydrogen production is expected to become the dominant future technology pathway.

Hydrogen storage and transportation technologies include:

gaseous hydrogen storage;
liquid hydrogen storage;
solid-state hydrogen storage;
ammonia (alcohol)-based hydrogen storage;
underground hydrogen storage;
and other approaches.

In the power sector, hydrogen energy can generate electricity mainly through:

hydrogen gas turbines;
hydrogen internal combustion engines;
hydrogen fuel cells.

Different LDES Technologies Demonstrate Distinct Competitive Advantages

Different long-duration energy storage technology pathways demonstrate diverse technical characteristics and competitive advantages.

In terms of efficiency, pumped hydro storage and gravity energy storage achieve relatively high efficiency, while molten salt thermal storage and hydrogen energy storage have comparatively lower efficiency.

Regarding service life, physical energy storage technologies such as pumped hydro storage, compressed air energy storage, and gravity energy storage generally offer longer lifetimes.

In terms of safety, most LDES technologies demonstrate high safety levels, except hydrogen energy storage, which requires additional safety considerations.

Regarding environmental adaptability, pumped hydro storage and compressed air energy storage have relatively limited adaptability to certain environmental conditions.

In terms of response speed, flow batteries demonstrate significant advantages.

Lifecycle Cost of Energy Storage Determines Economic Competitiveness

The levelized cost of electricity (LCOE) over the full lifecycle is a key indicator for evaluating the economic performance of energy storage technologies.

According to estimates from the China Energy Storage Alliance (CNESA), when the storage duration reaches 8 hours, salt cavern compressed air energy storage and pumped hydro storage currently demonstrate relatively lower lifecycle electricity costs.

With continuous technological advancement and large-scale deployment, the lifecycle costs of emerging long-duration energy storage technologies are expected to continue declining.

According to projections, by 2035, mainstream LDES technologies including:

compressed air energy storage;
pumped hydro storage;
flow batteries;
molten salt thermal storage;

could achieve lifecycle electricity costs of approximately:

RMB 0.3–0.5/kWh

under conditions of 250 annual utilization cycles.

If calculated based on each technology’s inherent lifecycle cycle life, the lifecycle cost of energy storage could decline even further.

Revenue Channels Established, Value of Long-Duration Storage Yet to Be Fully Released

Currently, the development of market mechanisms for long-duration energy storage is accelerating its transition from policy-driven growth toward market-driven development.

The three-part revenue structure of:

“Energy Market + Capacity Market + Ancillary Services Market”

is gradually moving from the stage of framework establishment toward detailed implementation.

Energy Market: The Most Fundamental Revenue Source

The energy market is currently the most fundamental and primary revenue source for long-duration energy storage.

The core business logic is:

“Charge during low-price periods and discharge during high-price periods.”

Compared with 2-hour energy storage systems, the key advantage of LDES lies in its ability to provide:

cross-period energy shifting;
large-scale electricity time-shifting capability;
and flexible short-term operation.

Some technology pathways can also achieve multiple daily cycles, allowing them to capture more price arbitrage opportunities.

In provinces where electricity spot markets are relatively mature, peak-valley price differences have become a major revenue source for energy storage projects.

Taking compressed air energy storage as an example, the first phase of the Jintan Salt Cavern Compressed Air Energy Storage National Demonstration Project in Jiangsu, which began operation in 2024, has an installed capacity of:

60 MW / 300 MWh

The project can achieve:

one charge and two discharge cycles per day;
or multiple charge-discharge operations within a day.
Capacity Market: Providing Long-Term Reliability Value

Unlike the “price arbitrage” mechanism of the energy market, the core logic of the capacity market is the “value of availability” — meaning that energy storage systems commit to remaining available whenever the power grid requires support.
This mechanism is particularly important for long-duration energy storage because:

it requires higher upfront investment costs;
it has a longer payback period;
and it requires stable baseline revenues to improve project bankability.
Currently, the development of capacity markets in China demonstrates a dual-track approach, which is gradually removing market access barriers for long-duration energy storage.
On one hand, the coal-fired power capacity pricing mechanism began nationwide implementation in 2024, providing a stable revenue foundation for the transformation of thermal power generation.
On the other hand, the Notice on Improving the Capacity Electricity Pricing Mechanism for the Generation Side, released in January this year, established for the first time at the national policy level a capacity electricity pricing mechanism for independent new-type energy storage systems on the grid side.
Based on the principle of “equal pay for equal performance,” independent energy storage has officially been incorporated into the generation-side capacity pricing mechanism.
The capacity payment mechanism for independent energy storage has therefore evolved from regional exploration toward a nationwide unified framework.

Ancillary Services Market: Unlocking Additional Value

If the energy market addresses the question of “whether energy storage can generate revenue,” the ancillary services market determines “whether energy storage can generate additional value.”
Currently, power ancillary service markets mainly include three categories:

frequency regulation;
peak shaving;
backup reserve.
In regions where electricity spot markets operate on a regular basis, peak-shaving ancillary services have gradually been replaced by spot energy markets, with their original functions being absorbed by electricity trading mechanisms.
Meanwhile, some provinces have begun pilot programs for new ancillary services, including:
ramping support;
inertia support;
and other grid flexibility services.
Long-duration energy storage can provide:
long-cycle energy shifting;
backup reserve capability;
and some technology pathways can also provide physical inertia, effectively supporting grid stability requirements.
However, although the three-part revenue structure appears relatively complete, the current market mechanism still mainly focuses on the question of “whether energy storage exists”, without further distinguishing “how long energy storage can provide service.”
The differentiated advantages of LDES — including:
cross-time energy shifting;
large capacity;
high reliability;
have not yet been fully translated into market revenues.
This remains the most significant challenge in current market mechanism development and represents a key area requiring further breakthroughs.
Technology and Market Mechanisms Advancing Together to Support Demonstration Deployment
At the recently held Energy Storage International Conference and Expo (ESIE2026), Ma Yuan, Assistant Researcher at the Department of Earth System Science of Tsinghua University, stated that by 2030, energy storage capacity should account for 15%–20% of total renewable energy installed capacity, reaching a key milestone of approximately 400 GW.
Among this capacity, long-duration energy storage with durations exceeding 8 hours should account for at least 20% in order to effectively reduce renewable energy curtailment and ensure power system security.
According to forecasts from the China Energy Storage Alliance (CNESA), during the 15th Five-Year Plan period, demand for long-duration energy storage will gradually become more prominent.
New LDES demand during this period will mainly focus on storage durations of:
4–10 hours
Under a conservative scenario, the market scale is expected to reach:
180 GW
while under an optimistic scenario, it could reach:
250 GW
Pumped hydro storage will remain the dominant technology, complemented by emerging LDES technologies such as:
compressed air energy storage;
electrochemical energy storage.
However, this scale still falls short of the requirements of power grid companies.
In some northwestern provinces with high renewable energy penetration, demand for 24-hour-plus long-duration energy storage is expected to emerge first.
By 2035, the scale of long-duration energy storage is expected to reach:
300 GW under a conservative scenario;
400 GW under an optimistic scenario.
Storage durations will mainly range from:
4–24 hours
while the deployment scale of emerging LDES technologies will continue to increase.
Accelerating the Transition from Technology Demonstration to Large-Scale Deployment
To continuously promote the transition of long-duration energy storage from technology demonstration to large-scale commercial application, more projects need to be implemented to transform technological maturity into commercial viability.
1. Coordinated Demonstration of Different Technology Pathways
Currently, emerging LDES projects face challenges including:
technologies that are not yet fully mature;
incomplete industrial supply chains;
relatively high investment costs.
As a result, commercial applications remain dominated by short-duration lithium-ion battery energy storage.
Going forward, demonstration and deployment of LDES technologies should be promoted in an orderly manner based on different stages of technological development.
This approach will accelerate the implementation of emerging technologies while driving industrial technology upgrades and improving market competitiveness.
2. Promote Scenario-Specific Demonstration Projects Based on Local Conditions
Under the new power system framework, different application scenarios have different requirements for long-duration energy storage.
For example:
developed cities in eastern China have relatively higher requirements for energy density;
northwestern “desert, Gobi, and barren land” regions;
eastern coastal areas;
and cold regions in northeastern China;
all have different requirements regarding:
operating temperature;
humidity resistance;
sand and dust protection;
and environmental adaptability.
Therefore, demonstration projects should be combined with different application environments to deepen research into key technologies including:
energy storage equipment;
system integration;
safety protection;
and operational reliability.
3. Strengthen Long-Term Monitoring and Evaluation of Demonstration Projects
Currently, management and evaluation mechanisms for demonstration projects are not yet sufficiently comprehensive.
In the future, long-term tracking, monitoring, and periodic evaluation should be carried out for demonstration projects.
This will provide scientific data support for:
the practical application of new technologies;
new products;
and innovative solutions.
It will also provide evidence-based support for national industrial policies and technical standards.
4. Encourage Demonstration Projects to Explore Innovative Policies and Business Models
While demonstrating LDES technologies, pilot projects should also serve as platforms for exploring innovative commercial models.
At the same time, improving policy mechanisms and market support systems will be a critical foundation for large-scale LDES development.
Establishing Cost Recovery Mechanisms for Long-Duration Energy Storage
Compared with short-duration energy storage, LDES demonstrates greater value through:
capacity contribution;
long-term backup capability;
and system reliability support.
Therefore, it is necessary to gradually establish market-based capacity cost recovery mechanisms.
Through market competition and pricing mechanisms, investment entities can be encouraged to make reasonable investments, ensuring long-term adequacy of power system capacity.
Improving Cost Allocation Mechanisms for Long-Duration Energy Storage
Long-duration energy storage can directly or indirectly accelerate the replacement of traditional fossil fuel power generation with renewable energy, significantly reducing overall societal carbon emissions.
In the future, policy and market frameworks for:
green electricity;
green electricity certificates;
carbon trading;
should be further developed.
These mechanisms can better reflect the value of LDES in:
energy transition;
carbon reduction;
and renewable energy integration.
By expanding revenue sources and improving cost allocation mechanisms, the economic foundation for long-duration energy storage can be further strengthened.

Conclusion

Long-duration energy storage is becoming an increasingly important pillar of future power systems as renewable energy deployment accelerates.
With continuous technological innovation, improved market mechanisms, and increasing project deployment, LDES is expected to move from early-stage demonstration toward large-scale commercialization.
The future development of long-duration energy storage will depend not only on breakthroughs in individual technologies, but also on the coordinated evolution of:
technology pathways;
market structures;
business models;
and policy frameworks.
Together, these factors will unlock the full value of LDES in supporting renewable energy integration, enhancing grid flexibility, and enabling the global energy transition.
