BNEF: Energy to storage increase 122X by 2040

Published onAugust 8, 2019

According to the latest forecast by BloombergNEF (BNEF), energy storage installations (not including pumped hydropower) around the world will multiply exponentially, from 9GW/17GWh deployed as of 2018 to 1,095GW/2,850GWh by 2040. This 122-fold boom of stationary energy storage over the next two decades will require $662 billion of investment, according to BNEF estimates. It will be made possible by further sharp declines in the cost of lithium-ion batteries, on top of an 85% reduction in the 2010-18 period. BNEF’s Energy Storage Outlook 2019, published on July 31, predicts a further halving of lithium-ion battery costs per kilowatt-hour by 2030, as demand takes off in two different markets – stationary storage and electric vehicles. The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar. Yayoi Sekine, energy storage analyst for BNEF and co-author of the report, said:  “Two big changes this year are that we have raised our estimate of the investment that will go into energy storage by 2040 by more than $40 billion, and that we now think the majority of new capacity will be utility-scale, rather than behind-the-meter at homes and businesses.”
