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.
Water is often used to store thermal energy. Energy stored - or available - in hot water can be calculated Water is heated to 90oC. The surrounding temperature (where the energy can be transferred to) is 20oC. The energy stored in the water tank can be calculated as A solar energy water buffer tank with 200 US gallons is heated 200oF.
In particular, a water flow decrease and temperature increase in rivers can significantly limit the generation of electricity. This paper investigates the issues to energy conversion stemming from the water-energy nexus and mitigates them by developing a model for the smart utilization of water resources.
The total potential of nominal energy storage capacity in the US at the 2,075 facilities identified is between 34.5 and 45.1 TWh (using 50% of the minimum and maximum reservoir capacities reported in dam or reservoir inventories i.e., EInv_min, and EInv_max, respectively).
