Enabling longer duration storage and non lithium-ion technology, what to do with the storage capabilities of electric vehicles and how the industry is overcoming regulatory hurdles were all key topics discussed at this year’s Energy Storage Summit in London.

The UK energy storage is currently “in limbo” despite improvements to regulation made in recent years, according to panellists at the Energy Storage Summit.

Hydrogen and vehicle-to-grid (V2G) technologies are among those vying to be considered the next big innovation in energy storage, a panel of experts has concluded.

A representative of National Grid, the UK’s transmission system operator (TSO), has said that energy storage will be “integral” to the network’s flexibility strategy – while urging developers not to rely solely on early frequency regulation contracts.
