European project CompassCO2

COMPASsCO2 aims to integrate CSP particle systems into highly efficient s-CO2 Brayton power cycles for electricity production.

To reach this goal, the consortium will produce tailored particle and 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. The proposed innovative CSP s-CO2 Brayton cycle plants will be flexible, highly efficient, economic and 100% carbon neutral large-scale electricity producers.

The consortium is led by the German Aerospace Centre DRL and comprises 11 other institutions from 7 European countries, including companies, universities and research centres.

Sugimat participates in the project through the construction of a heat exchanger that uses, on the one hand, PARTICLES coming directly from the concentrating solar tower at very high temperatures, and on the other hand, CO2 in supercritical state, at very high pressures and temperatures. The working conditions to which the heat exchanger is subjected, on both sides, make the design, the choice of materials for its construction and the manufacturing processes of the machine a technological challenge.

The project will run for four years and is fully funded by the European Commission, with a total budget of just under six million euros.


“This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 958418”.
