CO2OLHEAT · Supercritical CO2 power cycles demonstration in Operational environment Locally valorising industrial Waste Heat

CO2OLHEAT will demonstrate at TRL7 in the CEMEX cement manufacturing plant in Prachovice (CZ) the operation of a 2 MW Waste-Heat-to-power (WH2P) skid based on a 2MW-sCO2 cycle able to efficiently valorize local waste heat at a significant temperature of 400°C. Capitalizing consortium excellent knowledge coming from previous sCO2 turbomachinery design experience and EU funded projects on industrial waste heat valorisation (TASIO, i-THERM, sCO2-FLEX etc.) and stimulated by SPIRE roadmap and EU sCO2 R&D initiatives, CO2OLHEAT aims to valorize waste heat even at higher temperature if compared with the traditional steam/ORC solutions. The project will demonstrate the EU MW scale first-of-a-kind waste heat-sCO2 plant towards a cheaper/more flexible waste heat valorisation. The project will strengthen EU industrial leadership in both energy intensive industries (making them more competitive) and turbomachinery sectors, bridging the current gap on sCO2 turbomachinery that EU has with US and Japan-Korea. The project will analyse sCO2 WH2P potential from a technical, economic and environmental point of view, developing innovative models for the design of the cycle and of the turbomachinery as well as investigating CO2OLHEAT cycle benefits in the cement, glass, aluminium, power generation sectors via techno-economic and Life Cycle based replication feasibility studies, involving relevant EU industrial players (EDF, ENGIE, MYTH, CEMEX, SISECAM, CELSA). The project is coordinated by ETN and involves an industry driven consortium with key turbomachinery OEM (SIE-BH), energy intensive industries, energy utilities and R&D partners all committed to bring soon CO2OLHEAT sCO2 cycle technologies on the market. Thanks to its robust demonstration and replication campaign (also foreseeing extra-EU stakeholders collaboration), CO2OLHEAT can be considered a “demonstration to market” project, being keystone for EU sCO2 turbomachinery industry and for a more effective waste heat valorisation.
