Hundreds of used electric vehicle battery packs are enjoying a second life at a California facility connected to the state's power grid, according to a company pioneering technology it says will dramatically lower the cost of storing carbon-free energy. B2U Storage Solutions Inc, a Los Angeles-based startup, said it has 25 megawatt-hours of storage capacity made up of 1,300 former EV batteries tied to a solar energy facility in Lancaster, California. The project is believed to be the first of its kind selling power into a wholesale market and earned $1 million last year, according to Chief Executive Freeman Hall.
