The U.S. Department of Energy’s Office of Fossil Energy and Carbon Management is investing $2.4 million in three projects that are exploring the potential of energy storage technologies to shrink the carbon footprint of existing fossil fuel plants.
The technologies — including high-temperature thermal energy storage and hydrogen storage — could help bolster grid reliability and affordability, while also potentially supporting the Biden administration’s goal to decarbonize the electric grid by 2035, according to DOE.
As the grid is increasingly powered by non-emitting resources, storage will play a role in matching variable generation with load, Haresh Kamath, the Electric Power Research Institute’s program manager for energy storage, said. “This [effort] puts it in place in locations already connected up to the grid” and creates a pathway for these assets to be transitioned from fossil fuels to storage, he added.
