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.
A thermal power plant, also known as a thermal power station, is used to transform heat energy into electric power for domestic and industrial applications. Electric power is generated by steam-powered turbines, which convert heat to mechanical power. So let''s understand the basics of a thermal power plant.
