The cost of Lithium-ion battery packs has fallen close to 90%, and rates lower than US$100/kWh have been reported for the first time, foreshadowing rapid declines across the energy storage market.

A new consortium, V2GB (Vehicle to Grid Britain), will develop driver-centred business models to support the rapid roll out of vehicle-to-grid (V2G) technologies, enabling millions of electric car batteries to become a vital part of the UK energy system. National Grid, carmaker Nissan’s European Technical Centre, Moixa and energy consultancy Element Energy have come together to help work out how to reward drivers who use electric vehicle (EV) batteries to support the power network. Chris Wright, the Chief Technology Officer of UK home battery company Moixa, talks us through the mission behind V2GB and the potential impact of the study.
