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.

A ceremony was held yesterday in Niedersachsen, Germany, to welcome the start of operations at a ‘hybrid’ energy storage plant that will use a combination of sodium-sulfur and lithium-ion batteries to stabilise the grid.
