Abstract. Compressed air energy storage (CAES) stores energy as compressed air in underground formations, typically salt dome caverns. When electricity demand grows, the compressed air is released through a turbine to produce electricity. CAES in the US is limited to one plant built in 1991, due in part to the inherent risk and uncertainty of developing

6 FAQs about [Using reservoirs for energy storage]

What is reservoir thermal energy storage?

A reservoir is a geothermal resources Tools to evaluate reservoir thermal energy storage (RTES; heat storage in slow-moving or stagnant geochemically evolved permeable zones in strata that underlie well-connected regional aquifers) are developed and applied to the Columbia River Basalt Group (CRBG) beneath the Portland Basin, Oregon, USA.

Do hydropower reservoirs need water and energy storage?

Long-term planning and operation of hydropower reservoirs require an understanding of both water and energy storage. As energy storage needs of the evolving grid increase, we must account for the water and energy storage potential of these reservoirs.

Why is storage in hydropower reservoirs important?

Storage in hydropower reservoirs is important to the management of both water resources and the electric grid, especially with variable water availability and evolving grid needs.

How can we calculate energy storage capacity at hydropower reservoirs?

By combining existing inventories of surface water (reservoirs and streamflow) and hydropower infrastructure (dams and power plants), we can calculate nominal energy storage capacity at hydropower reservoirs for the entire US.

How much electricity can a hydropower reservoir store?

IEA estimates for global hydropower reservoir “equivalent electricity storage capabilities” are 1,500 TWh, 176 times the current global pumped-storage capability of 8.5 TWh (IEA, 2021 ).

What is the maximum volume of a reservoir?

The maximum volume of the reservoir equals to 11% of the annual river flow, from which the need for storage is divided by seasonal storage needs and inter-annual storage needs. This value was selected with the intent of reducing the environmental impact of storage on the overall river flow.
