Last week, Massachusetts Institute of Technology (MIT) based (and U.S. Department of Energy-funded) researchers reported that they have developed an “air breathing” battery capable of storing electricity for long periods of time at about $20 a kWh. For its anode, the rechargeable flow battery uses cheap, abundant sulfur dissolved inContinue Reading

Battery electricity storage is a key technology in the world’s transition to a sustainable energy system. Battery systems can support a wide range of services needed for the transition, from providing frequency response, reserve capacity, black-start capability and other grid services, to storing power in electric vehicles, upgrading mini-grids andContinue Reading
