Calm before the Q2 storm: US energy storage market posts decent Q1

WoodMac looks back at the storage industry in simpler, long-ago times — eight weeks ago.

Used EV batteries for large-scale solar energy storage

MIT scientists have suggested that used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid-scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.

Lithium-ion storage is here to stay with no ‘post Li-ion’ era in sight

A German-Israeli research group has gathered to discuss which storage technologies may outperform lithium-ion batteries in the future. They concluded that there is no such a thing as a “post Li‐ion” era in sight. They recommended a “side‐by‐side” approach for multiple technologies in different applications, as well as the hybridization of technologies.
