How can NREL develop transformative energy storage solutions?

To develop transformative energy storage solutions, system-level needs must drive basic science and research. Learn more about our energy storage research projects . NREL's energy storage research is funded by the U.S. Department of Energy and industry partnerships.

How does NREL energy storage work?

In a new NREL-developed particle thermal energy storage system, silica particles are gravity-fed through electric resistive heating elements. The heated particles are stored in insulated concrete silos. When energy is needed, the heated particles are fed through a heat exchanger to create electricity for the grid.

How many MWh can a thermal energy storage system store?

The baseline system is designed for economical storage of up to a staggering 26,000 MWh of thermal energy. With modular design, storage capacity can be scaled up or down with relative ease.

What is thermal energy storage?

Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks - can store thermal energy.

What is the future of energy storage?

Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.

Could long-duration energy storage reshape utility-scale energy storage?

One of the key factors the SFS examined is long-duration energy storage—large batteries on the grid designed to store up to 10 hours worth of energy—and how it could reshape the role of utility-scale storage.
