At this temperature, the unit cost of energy stored in concrete (the thermal energy storage medium) is estimated at $0.88–$1.00/kW h thermal. These concrete mixtures, used as a thermal energy storage medium, can potentially change solar electric power output allowing production through periods of low to no insolation at lower unit costs. 1.
Rajandrea Sethi, in Encyclopedia of Energy Storage, 2022 The expression Underground Thermal Energy Storage (UTES) identifies shallow geothermal systems where heat from external sources (solar thermal collectors, industrial processes, combined heat and power systems) is stored seasonally into the ground to be used during periods of higher demand.
Underground Seasonal Thermal Storage when combined with Medium Temperature Renewable Energy (such as Vacuum Tube Solar Collectors) has a promising potentials. Proper design and knowledge of building's energy demand is a key success factor for seasonal thermal storage project.
Now it is being developed for a new purpose: cost-effective, large-scale energy storage. EPRI and storage developer Storworks Power are examining a technology that uses concrete to store energy generated by thermal power plants (fossil, nuclear, and concentrating solar ).
With concrete thermal energy storage, large concrete blocks are stacked in a location adjacent to a thermal power plant. When the plant’s power output is not needed by the grid, its steam is redirected from the plant’s turbines to tubes embedded in the blocks, storing the steam’s heat in the concrete.
In recent years there has been a depletion of natural resources, consumption of fossil fuels and a dire need for conserving energy. Thermal storage concrete is a new type of concrete that is likely to store and conserve energy and thereby serving towards a greener environment.
