This is hardly a surprise, but maybe that is just testament to the daily diet of growth stories we see in the energy storage sector. Of course this article refers to Sony joining the EV battery race, but as we've seen this week in the BNEF report, second life EV batteries will have an important part to play in the stationary energy storage sector.

This is on top of the recent announcement from Samsung SDI opening a battery manufacturing factory in Hungary. We've also seen and hear of aggressive growth strategies at Panasonic, LG Chem and BYD. With such financial muscle and R&D expertise expect to see costs tumbling as they have in the Solar PV sector for the last decade and more. Exciting times.
