With nearly half of global emissions coming from heat processes, clean long duration energy storage (LDES) which can store thermal energy are crucial for decarbonisation, says a new LDES Council report.

Invinity Energy Systems and Eos Energy Enterprises are providing long duration energy storage systems to the ‘biggest renewables microgrid project in the US’, being developed for the Viejas Tribe of Kumeyaay Indians in Southern California.

Duke Energy would still choose lithium-ion for an upcoming 7.3-hour duration energy storage system in Florida if it redesigned the project today, a spokersperson told Energy-Storage.news.

Significant policy support for the long duration energy storage (LDES) sector may be needed until 2030-35 when the market matures, says a new LDES Council policy toolbox report.

Energy conversion equipment specialist Ingeteam will supply a 70MW/340MWh battery energy storage system (BESS) in northern Italy for a 2023 delivery date.

Zinc battery energy storage system provider Eos Energy Systems finished 2021 with an order backlog of US$148.7 million and a net loss for the year of US$124.2 million.

Long duration energy storage (LDES) technologies may have a difficult time competing with lithium-ion over the next decade as the latter’s cost-competitiveness at longer durations increases, possibly even to 24 hours, according to Haresh Kamath, Electric Power Research Institute (EPRI).

The implementation of regulative security is all that is needed to bring in investment for long duration storage.

ron flow battery provider ESS Inc has revealed a US$477 million net loss in 2021, in its first full-year results since becoming a publicly-traded company on the New York Stock Exchange (NYSE).
