“The energy storage system is expected to supply enough power for up to 200,000 residents each day. We’ve seen this idea explored through a 120-MW redox flow battery built in underground salt caverns, supplying enough daily power for 75,000 homes in Jemgum in northwestern Germany.”

“Flow batteries are a new entrant into the battery storage market, aimed at large-scale energy storage applications. This storage technology has been in research and development for several decades, though is now starting to gain some real-world use. Flow battery technology is noteworthy for its unique design. Instead of a single encased battery cell where electrolyte mixes readily with conductors, the fluid is separated into two tanks and electrons flow through electrochemical cells and a membrane which separates them.”

Energy storage is increasingly important for a diversity of applications. Batteries can be used to store solar or wind energy providing power when the Sun is not shining or wind speed is insufficient to meet power demands. For large scale energy storage, solutions that are both economically and environmentally friendly are limited. Flow batteries are a type of battery technology which is not as well-known as the types of batteries used for consumer electronics, but they provide potential opportunities for large scale energy storage.
