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:

1. Improving intrinsic battery safety through interdisciplinary research and AI technologies to reduce thermal runaway probability below 10⁻⁸;

2. Enhancing process safety through intelligent thermal management materials, fiber-optic in-situ monitoring, and integrated thermal management and early-warning technologies;

3. 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.

12.8 GWh Energy Storage Cluster Connected to the Grid AI-Powered Energy Storage Reshapes the Future of New Power Systems

Recently, the world’s largest single-site electrochemical energy storage power station—the Envision Jingyi Chagan Hada Energy Storage Power Station—was successfully connected to the grid. With a total capacity of 4 GWh, the project is fully equipped with Envision’s AI-powered energy storage system. This milestone marks the completion and grid connection of Envision’s 12.8 GWh energy storage cluster deployed across Bayannur, Ordos, Hohhot, Ulanqab, Xilingol League, and Alxa League. To date, Envision-led energy storage projects in Inner Mongolia exceed 14 GWh in total capacity.

The project passed grid verification at rated power through “three charge and three discharge” and a 72-hour continuous trial operation at one time, becoming the largest energy storage project in China to complete such testing. This achievement not only sets new global records for energy storage cluster scale and grid-connection speed, but also demonstrates Envision’s capabilities in ultra-large-scale system integration, extreme-environment adaptability, deep grid interaction, and large-scale project delivery.

Notably, the project’s grid connection coincided with the release of China’s Guidelines on Promoting High-Quality Power Grid Development by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA), highlighting strong alignment between national policy direction and industrial practice. Together, they signal that AI-centered energy storage technologies are reshaping the future of new power system from technological, market, and application perspectives.

Technology: From “Optional” to “Essential”

The Guidelines clearly state that power system regulation capabilities should be upgraded toward greater diversity and massive-scale coordination. They call for accelerated development of regulation capabilities for new grid-connected entities, including distributed renewable energy and new-type energy storage, to enable the coordinated and optimized dispatch of diverse and large-scale resources. The Guidelines also emphasize strengthening R&D in critical power grid technologies, targeting application scenarios such as deserts, Gobi and barren regions, integrated wind–solar–hydro systems, high-altitude areas, and deep and far-offshore environments. They propose piloting long-distance transmission from large-scale 100% renewable energy bases, and accelerating the engineering validation and deployment of grid-forming technologies.

It is said that Envision’s AI energy storage system deployed in Inner Mongolia integrates advanced capabilities from “grid-following” to “grid-forming”, enabled by a full-time-scale simulation platform and a three-layer grid-forming architecture spanning equipment, system, and site levels. This allows GW-scale stations to connect to the grid immediately upon energization, significantly reducing commissioning time, mitigating oscillation risks, and enhancing system support strength. As a result, energy storage evolves from a “grid follower” to a “grid builder,” providing a solid technical foundation for power systems with high shares of renewable energy.

Market: From Grid Connection to Market Participation

The Guidelines emphasize deep integration between market mechanisms and dispatch systems, and encourage exploration of new pricing mechanisms. This creates clear and predictable revenue pathways for AI-powered energy storage through participation in electricity spot markets, provision of ancillary services such as frequency and peak regulation, and access to capacity compensation and price arbitrage.

The 12.8 GWh energy storage cluster will be fully integrated into the electricity spot market. Leveraging Envision’s AI system—where trading agents and grid-forming agents operate in coordination—the project enables a closed-loop lifecycle operation covering forecasting, dispatch, trading, and self-learning. This approach not only enhances the intelligence, efficiency, and execution of power trading decisions, but also provides a replicable and scalable model for the large-scale participation of new-type energy storage in electricity markets. At the same time, it significantly improves regional renewable energy consumption and strengthens the operational resilience of the power grid. In previous deployments, Envision’s AI energy storage system has ranked first in trading forecast accuracy at several sites in Inner Mongolia for consecutive months. Based on measured operational data, the project is expected to increase total lifecycle returns by more than 20%.

Applications: From Single Use to Broad Scenarios

The Guidelines elevate smart microgrids as a key component of new-type power systems, unlocking vast opportunities for AI energy storage in industrial parks, zero-carbon parks, and remote areas. In these scenarios, AI-powered energy storage functions as a local energy brain, optimizing the coordination of generation, grid, load, and storage to maximize renewable self-consumption, enhance supply reliability, and enable higher-level grid interaction.

As power systems become increasingly clean and market-oriented, simple equipment aggregation is no longer sufficient. In high-renewable scenarios, AI-driven energy storage that balances grid stability with revenue optimization has become indispensable. The successful grid connection of the Inner Mongolia cluster underscores Envision’s leadership in physical AI and AI-enabled renewable energy solutions.

Envision has established a full industrial chain in Inner Mongolia, from battery cells and system integration to project delivery and intelligent operation. Leveraging its integrated capabilities, the project drives industrial clustering, injects new momentum into the local economy, supports the development of a new-type power system, and underpins the region’s efforts to accelerate the construction of a nationally important energy and strategic resources base.

This milestone delivery marks a successful conclusion to Envision’s energy storage business expansion in 2025. Empowered by physical artificial intelligence, Envision has secured a series of major contracts both at home and abroad this year. Building on its established global footprint, the company has successfully expanded into ten strategic overseas markets, including Australia, Chile, Italy, and Poland. Looking ahead, Envision will continue to strengthen the foundational support for next-generation power systems through innovative products and world-class project execution, accelerating the global transition toward zero-carbon and driving a new era of shared prosperity powered by Chinese renewable energy technologies.

NVIDIA's 800V Architecture Reshapes AI Data Centers: 31 Core Industry Chain Companies Unveiled

Source: CNESA

---

“How big is AI's appetite? The power consumption of a large AI data center is comparable to that of a small-to-medium-sized city. More challenging is its power usage pattern, which is like a ‘roller coaster’: one moment it computes at full capacity, and power spikes to its peak; the next moment it exchanges data, and power consumption drops sharply.” Such drastic fluctuations overwhelm traditional power grids and backup power sources represented by UPS (Uninterruptible Power Supply).

Against this backdrop, NVIDIA's recently released 800V DC architecture white paper has significance beyond a simple technical upgrade. It explicitly proposes a key requirement for future AI data centers: the integration of advanced energy storage systems capable of fast response, instantaneous charge/discharge, and intelligent scheduling. This forward-looking guidance signals that the energy storage industry is poised for an AI-driven explosive growth opportunity.

The Energy Bottleneck of Computing Power and Architectural

Breakthroughs

To address this challenge, industry leaders led by NVIDIA have laid out a clear vision, outlining a “three-step” evolution roadmap for the entire sector, aiming to steadily move toward the ultimate 800V DC architecture.

The first step is a transitional solution, innovatively adopting a “side-mounted power cabinet” to physically separate power modules from the core computing area.

The second step, the mid-term solution, promotes the architecture from “distributed” toward “centralized.”

The third step, the ultimate solution, uses SST to achieve a “one-step” conversion from the grid's 10kV medium-voltage AC to 800V DC.

Overview of the 800VDC MGX Cabinet

To enable this new architecture to effectively handle power fluctuations, “hybrid energy storage” becomes an inevitable technical core. By organically combining supercapacitors (responding to millisecond-level surges), high-rate batteries (addressing second-to-minute demands), and large-scale energy storage systems, it forms a multi-layered, fast-response backup power system.

However, the new architecture also raises the technical threshold comprehensively.

Traditional silicon-based power chips, like inefficient old engines, can no longer meet the stringent requirements of 800V high voltage. Consequently, third-generation semiconductors represented by silicon carbide (SiC) and gallium nitride (GaN) have emerged.

In this new architecture, SiC acts as the “strongman,” stabilizing high-voltage conversion of tens of thousands of volts in components such as solid-state transformers (SST), while GaN, like a “sprinter,” delivers precise low-voltage power to GPUs inside servers at extremely high speed. They are not just a performance upgrade but the cornerstone enabling the entire new architecture.

The ultimate form of this technological revolution is embodied in the disruptive product, the solid-state transformer (SST). It uses a “high-speed direct route” approach to efficiently convert medium-voltage grid power directly into 800V DC required by data centers, eliminating energy losses from multiple intermediate conversions, saving tens of millions of kWh annually for a large data center.

Under light load, SST efficiency is 5% higher than traditional transformers

Improved Power Quality

Meanwhile, SST replaces heavy copper coils with advanced chips, achieving “silicon in, copper out,” reducing the power supply system footprint by more than half and freeing valuable space for core computing equipment. More importantly, it functions as an intelligent “energy router,” seamlessly integrating photovoltaics, energy storage, and other new energy sources, becoming an indispensable intelligent core for building future AI factories.

Technological and product transformation will ultimately lead to a reshaping of business models. Future competition will no longer be a battle of hardware parameters but a contest of “intelligence,” with suppliers required to evolve into solution providers “understanding computing power.”

This means energy systems must have predictive capabilities, anticipating computing load changes and proactively scheduling resources; simultaneously, they must coordinate intelligently, directing supercapacitors, batteries, and other energy storage units to work efficiently together.

In this transformation, true value is shifting from hardware itself to the control algorithms and software behind it. Future winners will no longer be mere equipment manufacturers but service providers capable of delivering integrated hardware-software intelligent energy solutions.
