The Status of LDES Startups
Long duration energy storage tech will be needed in the coming years for the grid...
While lithium-ion batteries have been able to address the need for multi-hour energy storage needs, there is still a need to develop technologies that can affordably store energy for days to weeks.
The need: The Department of Energy estimates that 4-hour lithium-ion batteries can support grids with up to 50% to 60% of variable renewable energy, but that long-duration energy storage (LDES) with 10+ hours of storage are needed much above that.
Funding is needed to support their development. To date, Eos Energy, Hydrostor, Form Energy and Plug Power have led the charge in capital raised.
