Recently, GB/T 42288-2022 "Safety Regulations for Electrochemical Energy Storage Stations" under the jurisdiction of the National Electric Energy Storage Standardization Technical Committee was released. This national standard puts forward clear safety requirements for the equipment and facilities, operation and maintenance, maintenance tests, and emergency disposal of electrochemical energy storage stations, and is applicable to stations using lithium-ion batteries, lead-acid (carbon) batteries, redox flow batteries, and hydrogen storage/fuel cells, other types of electrochemical energy storage stations can use it as a reference. The standard points out that the battery room/chamber should be equipped with an automatic fire extinguishing system, which is linked with the battery management system(BMS), fire detector or flammable gas detection device, air conditioner, and exhaust system, and has the functions of remote passive command start and emergency mechanical start. The minimum protection unit of the automatic fire extinguishing system should be a battery module, and each battery module should be equipped with a detector and a fire extinguishing medium nozzle separately. The fire extinguishing medium should specifically have good insulation and cooling properties, which can extinguish battery fires and electrical equipment fires and prevent re-ignition.
Inner Mongolia Government Releases Energy Storage Support Policy
On December 19, the Government of the Inner Mongolia Autonomous Region issued several policies (2022-2025) supporting the development of new energy storage technologies. These policies will support the large-scale development of new energy storage technologies such as lithium batteries, redox flow batteries, compressed air energy storage, and flywheels. The construction of renewable energy generation projects should be equipped with energy storage facilities according to the requirements, for new guaranteed grid-connected renewable energy projects, energy storage systems should be configured according to 15%&2h, and for new market-oriented grid-connected renewable energy projects, storage systems should be configured according to 15%&4h. The government will increase the implementation of time-of-use electricity prices, timely adjust the price difference between peak and valley electricity prices to more than 3:1, and create profit space for the development of energy storage. It will also establish a market-based compensation mechanism, and the independent energy storage stations can receive subsidies. The upper limit of subsidy is 0.35 yuan/kWh, and the subsidy will not last for more than 10 years. Independent energy storage stations will be encouraged to obtain income through market-oriented methods such as leasing and selling, but the corresponding capacity will no longer receive subsidies.
The Largest Single Liquid-cooled Energy Storage Station in China Was Connected to The Grid
On January 15, the 500MW+150MW/300MWh (energy storage) wind power project in Xinghe County, Ulanqab City was connected to the grid at full capacity, which started on May 8, 2022. Under the influence of many factors such as high technical difficulty, poor weather conditions and heavy epidemic prevention tasks, it took 8 months complete, creating the best record in the construction of wind power projects. At present, the project is the wind power grid-connected project with the largest energy storage configuration in the Inner Mongolia Autonomous Region, and it is expected that the annual power generation will reach 1.6 billion kWh, the annual output value will reach 460 million yuan, and the tax revenue will reach about 53 million yuan. The project, which is by far the largest single liquid-cooled energy storage power station in China, is considered to have laid a good foundation for the construction of a 10-million-kilowatt renewable energy base in Ulanqab City.
