Used EV batteries for large-scale solar energy storage

MIT scientists have suggested 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.
