Vehicle-to-grid (V2G) technology has gone into use at Johan Cruyff Arena in Amsterdam, with energy infrastructure installed onsite including a 3MW battery energy storage system allowing visitors to both charge their cars at the stadium and put power back into it.

NEC will be using so-called ‘liquid metal’ batteries produced by Ambri in projects that could require more than four hours’ duration of energy storage, the company announced at SPI / ESI this week.

There is no economic benefit from installing energy storage with solar PV in UK homes, a new study has suggested, adding that the cost of battery degradation would cost homeowners £400 (US$518) in the first year.
