In the envisaged solar-Brayton cycle, supercritical carbon dioxide (sCO₂) is used as working media. Concentrated solar radiation is absorbed and stored in solid particles until the heat is transferred to the sCO₂. Unique properties of sCO₂ (such as high density and low viscosity) allow reaching high efficiency of the energy conversion and very compact design of the components compared to conventional Rankine steam cycle. The EU-funded COMPASsCO₂ project will integrate solar energy into sCO₂ Brayton cycles for electricity production. The project will design, test and model tailored particle-alloy combinations able to face the extreme operating conditions regarding temperature, pressure, abrasion, oxidation and corrosion during the plant lifetime. Testing of the particle-sCO₂ heat exchanger will validate the innovative materials developed.
