The U.S. Department of Energy (DOE), in collaboration with various organizations, including the Edison Electric Institute’s Institute for the Energy Transition and the Electric Power Research Institute, recently hosted the LDES Summit in Washington, focusing on long duration energy storage technologies as a crucial component for transitioning away from fossil fuels. Xcel Energy highlighted its plans to deploy two 10 MW, 1,000 MWh systems with Form Energy at retiring coal plants, using iron-air batteries to bridge the gap left by decommissioned baseload power plants.

DOE's Assistant Secretary for Electricity emphasized the importance of long duration energy storage in building a resilient grid and announced significant funding to pilot LDES technologies across 17 states. Alliant Energy also discussed their project with Energy Dome for a carbon dioxide-based storage system and highlighted partnerships with local stakeholders for a sustainable energy transition, illustrating the potential benefits of innovative storage solutions to enable a cleaner and more efficient grid.
