NREL Analysis Reveals Benefits of Hydropower for Grid-Scale Energy Storage
Increasing the energy storage capacity can support a higher amount of renewable energy generation on the electric grid.
- Increasing the energy storage capacity can support a higher amount of renewable energy generation on the electric grid.
- The NREL study provides a life cycle assessment of new closed-loop pump storage hydropower in the United States and assesses its GWP.
- Pumped storage hydropower is compared against four other technologies: compressed-air energy storage (CAES), utility-scale lithium-ion batteries (LIBs), utility-scale lead-acid (PbAc) batteries, and vanadium redox flow batteries (VRFBs).
- “We looked at compressed-air energy storage, which allows for grid-scale energy storage and provides services like grid inertia and resilience.
