Project description
Particle-alloy combinations to face extreme operating conditions
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.
Objective
COMPASsCO2 aims to integrate solar energy into highly efficient supercritical CO2 Brayton power cycles for electricity production. Concentrated solar radiation is absorbed and stored in solid particles and then transferred to the s-CO2. In COMPASsCO2, the key component for such an endeavor shall be validated in a relevant environment: the particle-s-CO2 heat exchanger. To reach this goal, the consortium will produce, test, model and validate tailored particle-alloy combinations that meet the extreme operating conditions in terms of temperature, pressure, abrasion and hot oxidation/carburization of the heat exchanger tubes and the particles moving around/across them.
