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 ).

Can concrete store energy from thermal power plants?

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 ). Recent laboratory tests validated a Storworks Power design, setting the stage for a pilot-scale demonstration at an operating coal-fired power plant.

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.

Can you store green energy in giant concrete blocks?

Could this dark lump of concrete represent the future of energy storage?

This innocuous, dark lump of concrete could represent the future of energy storage. The promise of most renewable energy sources is that of endless clean power, bestowed on us by the Sun, wind and sea. Yet the Sun isn't always shining, the wind isn't always blowing, and still waters do not, in megawatt terms, run deep.

Is a concrete-based thermal energy storage system feasible?

However, there has been very little development in the design of a concrete-based thermal energy storage system. Most technical feasibility studies that focus on evaluating the potential for low-maintenance and low-cost concrete TES systems are based on the demonstrated DLR TES design [15,16].
