ETN sCO2 Working Group

Following ETN’s Technical Committee session on supercritical CO2 (sCO2) at our October Workshop in Florence, Italy, in 2019, the topic has been of high interest to ETN members. Plans to create a new ETN Working Group were announced during our virtual Annual General Meeting and Workshop in June 2020, and the Supercritical CO2 Working Group was officially launched in August 2020.

The objectives of the ETN sCO2 Working Group are to develop, enable and optimise the use of supercritical CO2 power cycles by:

• Highlighting potential use, applications and benefits.
• Paving the way for funding opportunities by highlighting the research needs on sCO2 based power cycles, in order to contribute to their deployment in the future energy system.
• Addressing operational issues/effects on components (turbomachinery, heat exchangers, combustion systems) related to the use of sCO2.
• Exploring market opportunities.
• Assessing and addressing operational safety aspects of sCO2-cycles based power plants.
• Fostering the use of sCO2 as working fluid for power generation.
• Creating a database of European open test beds 

Business case for sCO2 Waste Heat Recovery System

ETN’s “Business case for sCO2 Waste Heat Recovery System” report was published in October 2020 as part of the activities within ETN’s sCO2 Working Group. The report can be downloaded here.
