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.
The cooling effect of PV
Research from Finland’s Aalto University claims the residential cooling sector could sustain 540 GW of solar generation capacity if the world’s air conditioning systems were solar powered. Academics say synergies between PV and the cooling industry will become stronger as demand for the latter shifts nearer the equator, where seasonal differences in weather are less pronounced.
