USEA & EPRI: Seasonal Energy Storage Workshop


The total generation of variable renewable energy (VRE) including solar, wind, and hydropower in the United States often tends to peak in the spring. These low-carbon energy sources also tend to abate during the fall and winter months. To accommodate the use of this varying energy throughout the year in future decarbonization scenarios dominated by VRE, the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. There are several emerging technological solutions that may be suitable to address the need for seasonal energy storage, including low-carbon fuels such as hydrogen and ammonia, thermochemical energy storage, or geo-thermal energy storage. However, the value streams and fundamental economics of seasonal energy storage projects are not well-developed.

This workshop will outline a framework to define the need for seasonal energy storage, feature a group of emerging technologies that may be suitable for meeting the need, and discuss key economic structures needed to make seasonal energy storage projects viable. The workshop will provide a forum to discuss additional aspects of seasonal energy storage, including performance, costs, benefits, applications and use cases, technology gaps, and timelines to commercial readiness.

The workshop is free and open to public.
