Presentations of ETN’s fourth episode of the webinar series on R& Activities on sCO2 in Europe already available

We are very glad to announce that the presentations of the 4th webinar on R&D Activities on sCO2 Activities in Europe are now available for download.


Organised by ETN Global, coordinator of the CO2OLHEAT Project, this last event was focused on heat exchanger technology, since heat exchangers are core equipment of sCO2 systems with an expectedly strong impact on Capital Costs and performance. It is to note that event was part of the European Sustainable Energy Week (EUSEW), as a Sustainable Energy Day.


These are the talks that we had the opportunity to enjoy:

  • CFD-aided conceptual design of a cooler in sCO2 cycles for novel waste-heat-to-power (WH2P) plant layouts, Panagiotis Drosatos (CERTH)
  • Development of a high-efficiency particle-sCO2 heat exchanger for CSP applications, Maxime Rouzès (John Cockerill)
  • How additive manufacturing will help the energy sector: application to the primary heat exchanger in a sCO2 cycle, Damien Serret (TEMISTH)

SCARABEUS organizing a panel session at Turbo Expo 2022 to discuss the latest R&D activities funded by the European Commission

Prof. David Sánchez, dissemination manager of SCARABEUS, is currently working on a panel session where delegates from flagship projects on supercritical Carbon Dioxide technologies in Europe will discuss the impact of these activities on the progress of the technology. As of today, the following projects will be represented: SCARABEUS, CO2OLHEAT, SOLARSCO2OL and DESOLINATION.

The speakers will announced soon so watch out for further news!

SCARABEUS presented at the University R&D panel session of the 7th Supercritical CO2 Symposium in San Antonio, TX

SCARABEUS presented at the University R&D panel session of the 7th Supercritical CO2 Symposium in San Antonio, TX

The Dissemination Coordinator of the SCARABEUS project, Prof. David Sánchez of University of Seville, was invited to join the University R&D Panel organized at the last edition of the Supercritical CO2 Power cycle Symposium, hosted by Southwest Research Institute in San Antonio, TX.

The presentation proposed a staged vison for the development of Research and Innovation Actions with the ultimate goal to improve the lives of citizens. In this phased approach, universities and R&D centres drive R&D initially, with support by government and industry. Then, once the maturity of the technology increases, the industry takes over and the role of both R&D and government become secondary. Based on this framework, the speaker evaluated the development of supercritical Carbon Dioxide technology in the last twenty years, in order to trigger a discussion with the audience about whether or not this area of technology is actually following a credible, sustainable pathway.

The second part of the presentation presented the portfolio of projects involving supercritical CO2 technologies that is currently funded by the European Commission, along with their start/end dates and total funding. SCARABEUS was highlighted as a key enabling project to improve the economic viability of the technology, as justified by the results presented in this session (same presentation) and also in other technical sessions of the symposium.

The last part of the presentation shared some results of the survey that is currently being made by the supercritical Carbon Dioxide Working Group of the European Turbine Network. By the way, if you have not filled it in, do not miss the opportunity to do so at:

Quantis just completed the first phase of Life Cycle Assessment. Know a little bit about this crucial aspect of power plant assessment

Quantis is leading the environmental Life Cycle Assessment (LCA) assessment to evaluate the innovative SCARABEUS technology for CSP application with the objectives to (i) inform the key environmental performance indicator of the SCARABEUS technology development; (ii) to guide the development of the technology towards a more sustainable solution; (iii) to benchmark the SCARABEUS technology against alternative conventional and state of the art technologies.


LCA is a structured, comprehensive, and internationally standardized method. It quantifies all relevant emissions and resources consumed and the related environmental and health impacts and resource depletion issues that are associated with any goods or services (“products”). Life Cycle Assessment takes into account a product’s full life cycle: from the extraction of resources, through production, use, and recycling, up to the disposal of remaining waste.


                                                                 Figure 1: Workflow of Life Cycle Assessment.


Critically, the LCA approach help to avoid resolving one environmental problem while creating other unwanted “shifting of burdens”. LCA helps to prevent, for example, increasing land use or acid rain while reducing greenhouse gases, or increasing emissions in one country while reducing them in another. Life Cycle Assessment is a vital decision support tool to help effectively and efficiently make consumption and production more sustainable.
