China's first megawatt iron chromium flow battery energy storage demonstration project in Inner Mongolia


On February 28th, China's first megawatt iron chromium flow battery energy storage demonstration project was successfully put into trial operation in Inner Mongolia and will soon be put into commercial use. It is reported that the project has set a new record for the world's largest capacity of the technology.

The successful trial operation of the megawatt level iron chromium flow battery energy storage demonstration project involves the installation of an iron chromium flow energy storage system consisting of 34 "Ronghe No.1" battery stacks and 4 sets of storage tanks. The system utilizes the chemical characteristics of iron and chromium ions in the electrolyte to store electricity, which can store 6000 kilowatt hours of electricity. During the trial operation of the project, the key equipment ran smoothly and the indicator parameters were normal.

After being put into commercial use on a large scale, iron chromium flow batteries can safely, green, and store a large amount of electricity, and can store the electricity needed by cities in electrolytes for a long time, just like a city's "power bank". During low electricity consumption periods, renewable energy sources such as wind and solar energy can be used for charging, and then discharged during peak electricity consumption periods. In addition, this battery can also cooperate with conventional thermal power, nuclear power and other energy sources to provide auxiliary services such as peak shaving and frequency regulation for the operation of the power system, improving the flexibility of the power system.
