To date, typical battery technologies, like lithium-ion used in electric vehicles, have not been economically viable for wider adoption in longer-duration renewable power storage. With its new approach based on Iron-Air, Form Energy is looking to change this. Using iron to store electricity. Image used courtesy of Form Energy
The rated output power and capacity of the energy storage demonstration power station are 250 kW and 1.5 MW · h, respectively. When operated commercially on large scales, the iron-chromium redox flow battery technology promises new innovations in energy storage technology.
As an engineering case study, this paper introduces the 250 kW/1.5 MW · h ironchromium redox flow batteries developed for an energy-storage demonstration power station, which is under construction by SPICRI. The SPICRI station is Chinas first power station with a hundred-kilowatt-level storage capacity.
The nexus between clean electricity, long-duration electrical energy storage using iron-air batteries, and decarbonized iron production For deep decarbonization of the energy system, affordable energy storage capable of bridging intermittencies in the multi-day to seasonal generation of renewable electricity is essential.
Iron-air batteries, like those produced by Boston-based battery company Form Energy, can store 100 hours of energy, providing coverage for a days-long gap in renewable energy production.
The SPICRI station is Chinas first power station with a hundred-kilowatt-level storage capacity. The rated output power and capacity of the energy storage demonstration power station are 250 kW and 1.5 MW · h, respectively.
