New SCARABEUS paper by University of Seville discusses the benefits obtained from utilizing Carbon Dioxide – Sulphur Dioxide mixtures in (supercritical) Recompression cycles

27 March, 2022/in Conference and journal papers /by jose

The latest SCARABEUS research carried out by the team at University of Seville has just been published in Applied Thermal Engineering journal. Starting off from previous research by the the same partner, this paper provides a discussion on further efficiency gains that can be attained when Carbon Dioxide is blended with Sulphur Dioxide in supercritical or transcritical power cycles, with boundary conditions representative of those in a Concentrated Solar Power plant. The paper reveals that, unlike with other dopants tested previously by the consortium, this mixture performs best when in a transcritical Recompression cycle.

The paper is available in Open Access on the publisher’s website (link). Check the abstract below:

This paper investigates the interest and potential of using working fluids based on Carbon and Sulpur Dioxide mixtures (CO₂-SO₂) in a transcritical Recompression cycle. In order to assess the actual thermodynamic potential of the concept proposed, the influence of dopant (SO₂) content is assessed for two different turbine inlet temperatures (550ºC and 700ºC). The results obtained are compared with other CO₂ mixtures already proposed in literature (CO₂– C₆F₆ and CO₂-Ti Cl₄) and for two alternative cycle layouts (Recuperated Rankine and Precompression).

The results pf the analysis reveal that, at high ambient temperature, the Recompression cycle operating on CO₂-SO₂, with Sulphur Dioxide content between 20% and 30%(v), is a very interesting option for Concentrated Solar Power plants, able to achieve thermal efficiencies 45% and ¿51% at 550ºC and 700ºC respectively. At a minimum cycle temperature of 50ºC, the proposed configuration leads to thermal efficiency gains of 6% and 2% with respect to the Brayton and Recompression cycles working on pure CO₂. This performance enhancement of the Recompression cycle with CO₂-SO₂ is comparable to or higher than that enabled by other CO₂ mixtures proposed in literature, but with significantly higher specific work (smaller footprint) and temperature rise across the solar receiver (lower installation costs).

SCARABEUS presented at the University R&D panel session of the 7^th 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.
