A new report released July 31 details continued growth in global energy storage, driven by lower costs for lithium-ion batteries.
Research company BloombergNEF (BNEF) in its latest forecast published Wednesday said energy storage installations worldwide will grow across the next two decades, from the 9 GW/17 GWh of capacity deployed as of last year, to 1,095 GW/2,850 GWh by 2040, as battery costs fall by half by 2030 compared to today’s levels. It said two markets—stationary storage and electric vehicles—will drive demand for batteries.
BNEF said most of the new energy storage capacity for the power market is likely to be grid-scale.
Yayoi Sekine, a co-author of the report, in a news release said the latest research has “two big changes,” noting that “this year … we have raised our estimate of the investment that will go into energy storage by 2040 by more than $40 billion,” with BNEF forecasting $662 billion will be invested in storage over the next 20 years. Sekine, an energy storage analyst for BNEF, said, “We now think the majority of new capacity will be utility-scale, rather than behind-the-meter at homes and businesses.”
‘Energy Shifting’
BNEF’s analysis points to how less-costly batteries can be used in more applications, including “energy shifting,” or moving in time the dispatch of electricity to the grid, often during periods of excess solar and wind generation; peaking in the bulk power system, or using storage to deal with spikes in demand; and programs enabling customers to pay less for their electricity, by enabling the purchase of power at times when it’s cheaper, and storing it for later use.
Several speakers at Storage Week Plus, a July 23-25 energy storage conference in San Francisco, California, attended by POWER, noted how growth in storage likely is dependent on a continuing decline in battery cost, advancements in battery technology, and more applications for storage. Legal and regulatory mandates for storage also will play a role.
Thom Byrne, CEO of the clean energy investment group CleanCapital, told POWER his company is investing in “new markets and new renewable energy asset classes, with a specific focus on distributed solar and energy storage.” Byrne’s group earlier this month announced its largest acquisition to date with the purchase of Olympic, a 75.2-MW solar portfolio comprising 15 operating solar projects in New Jersey, from KDC Solar, a private, non-utility-affiliated owner and operator of large-scale commercial and industrial solar power generation.
CleanCapital’s investments are part of the growth forecast by BNEF. CleanCapital recently closed on a $300 million debt warehouse facility with Credit Suisse, leveraging funds managed by CarVal Investors, a global alternative investment fund manager.
