General Motors and Redwood Materials are joining forces yet again, this time with the intent to build energy storage units made out of new batteries and recycled EV packs. The two companies signed a non-binding memorandum of understanding to build energy storage out of US-manufactured batteries, as well as “second-life” EV packs from GM’s vehicles. The announcement comes on the heels of Redwood’s decision to move more aggressively into the energy storage business with the creation of a new division. The automaker says this new deal will help power its ambitions to expand beyond EV batteries and into grid management and energy storage. To meet that challenge, the U.S. needs energy storage solutions that can be deployed quickly, economically, and made right here at home.
