Iron-chromium liquid flow energy storage demonstration project

What is China's first megawatt iron-chromium flow battery energy storage project?

China’s first megawatt iron-chromium flow battery energy storage demonstration project, which can store 6,000 kWh of electricity for 6 hours, was successfully tested and was approved for commercial use on February 28, 2023, making it the largest of its kind in the world.

What is an iron-chromium flow battery?

An iron-chromium flow battery, a new energy storage application technology with high performance and low costs, can be charged by renewable energy sources such as wind and solar power and discharged during peak hours.

How many kilowatts can a chromium flow battery store?

Thanks to the chemical characteristics of the iron and chromium ions in the electrolyte, the battery can store 6,000 kilowatt-hours of electricity for six hours. A company statement says that iron-chromium flow batteries can be recharged using renewable energy sources like wind and solar energy and discharged during high energy demand.

Will China's first megawatt-level iron-chromium flow battery energy storage plant go commercial?

China's first megawatt-level iron-chromium flow battery energy storage plant is approaching completion and is scheduled to go commercial.

Can new energy storage complement pumped-hydro storage?

Liu Yafang, an official with the National Energy Administration, said that compared with traditional pumped-hydro storage, new energy storage can complement pumped-hydro storage and address the randomness and high volatility issues brought by the integration of new energy sources into the power system.
