ABraytCSPfuture

Highly efficient air-Brayton combined power cycles used in traditional power plants involve fossil fuels combustion via pressurised air.

The EU-funded ABraytCSPfuture project plans to develop a technology for air-operated concentrated solar power plants (CSPs) coupled to carbon-neutral air-Brayton gas turbine cycles. Researchers will demonstrate a first-of-its-kind compact, dual-bed thermochemical reactor/heat exchanger design. This unit will transfer heat from a non-pressurised air stream to a pressurised one, while also operating as a thermal booster, raising the temperature of the pressurised stream to the level required for Brayton cycles. Furthermore, the volumetric solar energy storage density of the CSPs will be significantly increased by using structured perovskite-based redox materials, prepared from cost-efficient and abundant raw sources, as the heat storage medium.
