The global energy storage market is poised to grow rapidly in the coming years, with Bloomberg New Energy Finance (BNEF) predicting $620 billion in investment over the next two decades will push cumulative global installations to 942 GW/2,857 GWh by 2040. Declining lithium-ion battery costs are driving much of this growth, with BNEF expecting the cost of utility-scale storage systems to fall roughly 52% through 2030, following an approximate 80% slide in the average price of lithium-ion battery packs in the first seven years of the current decade.
