The storage market is full of surprises. Last year, global storage installations were a third higher than expected, driven mostly by Chinese policy to attach batteries to renewables. 
Meanwhile, a ramp-up in manufacturing is causing oversupply – and a potential shakeout for smaller battery makers.
By 2030, the world could see 1.8 terawatt-hours of storage capacity installed, according to Bloomberg New Energy Finance. 
Rapid manufacturing expansion, a shift in chemistries and designs, and increases in duration for grid-connected systems are making battery storage one of the most dynamic sectors of the clean energy economy.
“We do have to constantly be reconsidering our assumptions,” said Yayoi Sekine, head of Bloomberg New Energy Finance. “I think now we're currently in an environment where the industry is actually able to sustain itself in terms of its own battery manufacturing and supply chains. That's a pretty big shift and that's happened very recently.”
This week on The Carbon Copy, we feature a conversation with Yayoi Sekine pricing, tech, manufacturing, and deployment trends that are shaping battery storage.
