How does concrete thermal energy storage work?

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.
