Where is China's first megawatt-level iron-chromium flow battery energy storage project located?

China's first megawatt-level iron-chromium flow battery energy storage project, located in North China's Inner Mongolia autonomous region, is currently under construction and about to be put into commercial use, said its operator State Power Investment Corp.

What is iron-chromium flow battery energy storage?

The megawatt iron-chromium flow battery energy storage project in north China's Inner Mongolia Autonomous Region uses a new energy storage application technology utilizing the chemical properties of iron and chromium ions in the electrolyte.

How a new energy storage system is developing in China?

Dai Jianfeng, a deputy chief engineer of China Electric Power Planning and Engineering Institute, said the new energy storage in China has been developed through diverse technology routes. According to him, lithium-ion battery is still dominant at present, but the development of compressed air and liquid flow battery is accelerating.

What percentage of China's Energy Storage is lithium ion?

As of the end of 2022, lithium-ion battery energy storage took up 94.5 percent of China's new energy storage installed capacity, followed by compressed air energy storage (2 percent), lead-acid (carbon) battery energy storage (1.7 percent), flow battery energy storage (1.6 percent) and other technical routes (0.2 percent).

What is a battery energy storage system?

A Battery Energy Storage System (BESS) secures electrical energy from renewable and non-renewable sources and collects and saves it in rechargeable batteries for use at a later date. When energy is needed, it is released from the BESS to power demand to lessen any disparity between energy demand and energy generation.

How many kWh can a spic battery store?

Built by the State Power Investment Corporation (SPIC), the project set a new world record for iron-chromium flow battery storage capacity. Consisting of 34 homegrown battery stacks and four groups of storage tanks, it can store up to 6,000 kWh of electricity every time.
