SOCRATCES (SOlar Calcium-looping integRAtion for Thermo-Chemical Energy Storage) is a research and innovation action with a total budget of 5 M€ aimed at aimed at demonstrating the feasibility of integrating Calcium Looping into CSP by erecting a pilot-scale plant that uses cheap, abundant, and non-toxic materials as well as mature solar and fluidized bed reactor technologies for energy storage. SOLARSCO2OL (SOLAR based sCO2 Operating Low-cost plants) is also an innovation action with a total budget of 13.4 M€ (10 M€ contribution by the EC) aimed at demonstrating the first MW Scale EU sCO2 power block operating in a real CSP plant.

 

A first technical session was held in the first part of the morning, where the project coordinators of SOCRATCES (Prof. Ricardo Chacartegui, University of Seville) and SCARABEUS (Prof. Giampaolo Manzolini, Politecnico di Milano) and a representative of the SOLARSCO2OL consortium (Mr. Antón López, Abengoa) shared the main characteristics, challenges and outcomes of the project, along with the foreseen future impacts on technology and society. The panel was chaired by Dr. Noelia Martínez (Abengoa), Exploitation Manager of SCARABEUS.

In the afternoon of the first day, the meeting continued at University of Seville for the partners of SCARABEUS who had the opportunity to discuss face-to-face for the first time since the beginning of the pandemic. On the second day, the meeting moved to the premises of Abengoa. Upon conclusion of the meeting, the partners agreed on the good progress made by all work packages, despite the inevitable impact of the shortage and higher prices of certain critical materials on the schedule of experimental activities. This is nevertheless not to be concerned about as the first set of equipment for testing has already been delivered to Technical Universty of Viena.

Communication event organized at University of Seville by the SCARABEUS consortium

/in /by

The next progress meeting of the SCARABEUS consortium will take place in Seville on the 20th and 21st of April 2022, hosted by University of Seville and Abengoa. This will be the first face-to-face meeting since October 2019 and all the partners are excited about it.

Alongside this meeting, the consortium has organized a communication event comprised of two main sessions. Session 1 will showcase the results produced by three research and innovation projects funded by the Horizon 2020 programme of the European Commission: SOCRATCES, SOLARSCO2OL and SCARABEUS. These three projects deal with Concentrated Solar Power technologies to enable large-scale energy storage (SOCRATCES), demonstrate the operation of supercritical Carbon Dioxide power cycles at megawatt scale (SOLARSCO2OL) and demonstrate the benefits of using supercritical CO2 mixtures in hot environments (SCARABEUS).

 

A second session will discuss the role of Concentrated Solar Power in the future energy landscape in Europe. Three high-level speakers representing the industry (Dr. Gonzalo Martín, PROTERMOSOLAR), R&D community (Dra. Ana Bernardos, CENER) and government (Dr. Sonia Fereres, Joint Research Centre of the European Commission) will share their views in a panel discussion enabling interaction with the audience.

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

/in /by

 

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 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.

The potential and technical challenges of the SCARABEUS project presented at the 7th Supercritical Power Cycles Symposium held at Soutwest Research Institute, TX

The team at University of Seville, on behalf of the consortium, presented the potential of the SCARABEUS project to overcome the main limitations experienced by all power cycles in the usually warm environments where Concentrated Solar Power facilities are located. High ambient temperatures are inherent to these sites and they set an intrinsic limit to the achievable thermal performance of the power block, which translates into larger solar fields and worse economic performance.

SCARABEUS is exposed to the same constraint but it also exhibits a much higher resistance to performance deterioration when ambient temperature increases. Nevertheless, there is no such thing as free lunch and this comes at the cost of technical and economic barriers that the consortium is currently working to overcome.
