October 18, 2023--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--Long-duration energy storage (LDES) technologies are the next Holy Grail in the pursuit of a clean energy economy. Late last month, the U.S. Department of Energy (DOE) (Washington, D.C.) selected several LDES projects to split up to $325 million in funding that will demonstrate the viability of intraday (lasting 10-36 hours) and multi-day (lasting 36 to 160-plus hours) energy storage technologies.

These selected projects will negotiate the funding terms with the DOE, which has not committed to funding the projects it selected. Funding applicants were required to submit a community benefits plan that outlined how proposed projects would meet a range of criteria.
