The fifth episode of the webinar series on R& Activities on sCO2 in Europe organized by ETN will take place on September 28th

As already published on this website, the CO2OLHEAT Project coordinated by ETN Global aims to demonstrate (at TRL7) 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 in the CEMEX cement manufacturing plant in Prachovice (CZ).


ETN Global initiated, in September 2022, a series of webinars aimed at providing a forum where the R&D activities in the area of supercritical Carbon Dioxide technologies can be disseminated and made known to a wider audience. This initiative has been joined by nine international and national projects, funded by the Horizon 2020 and Horizon Europe programmes of the European Commission (CO2OLHEAT, COMPASsCO2, SCARABEUS, DESOLINATION, SOLARSCO2OL, sCO2-4-NPP , ISOP) and by national R&D programmes in Germany (CARBOSOLA) and the Czech Republic (sCO2-Efekt).


The first webinar, held on September 22nd, aimed to introduce these projects in a single session, providing the main features of the project from technical and administrative standpoints. Opportunities for collaboration between projects and with stakeholders were also highlighted. Presentations can be downloaded from the SCARABEUS website: Link.


The second webinar took place on December 5th and presented a focus session discussing the fundamental and technical challenges posed for the design and operation of compressors in Supercritical Carbon Dioxide power systems. Three outstanding speakers covered these aspects; the session turned out very well and the feedback was very positive. Presentations can be downloaded from the SCARABEUS website: Link.


The fourth event was organised on June 12th, 14.00 – 15.30 CET, focused on heat exchanger technology, since heat exchangers are core equipment of sCO2 systems with an expectedly strong impact on Capital Costs and performance. Presentations can be downloaded from the SCARABEUS website: Link


This next event (5h in the series) will be held on September 28th , 14.00 – 15.00 CET, and will be focused on supercritical Carbon Dioxide expanders, which incorporate aspects of the past webinars such as aerodynamic design, turbomachinery seals, materials, etc. The lineup of presentations is as follows:

  • Which boundary conditions for CO2turbines?, Alberto Traverso (University of Genoa
  • Expander stage of an sCO2Companderfor 2 MW output power, Markus Sauerborn (Atlas Copco)
  • Benefits and design challenges of axial sCO2turbines, Stefan Glos (Siemens Energy)
  • Baker Hughes Design Experience with unfired Expanders, Andrea Paggini (Baker Hughes)
