Communication event organized at University of Seville by the SCARABEUS consortium

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.

 

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.

SCO2-Flex Final Event: The Role of sCO2 cycles in Europe’s future energy system

SCO2-Flex Final Event: The Role of sCO2 cycles in Europe’s future energy system

On the 16th June 2021 the Sco2-Flex project will host its final event to present the results of the project and also introduce 5 other Horizon 2020 projects working with sco2 technology. 

In the context of the EU’s energy transition, the last few years have seen the potential of supercritical CO2 (carbon dioxide) cycles emerge as an efficient replacement of steam in the cycles converting heat into power, leading to a more flexible and lower-emission electricity production.

 

Indeed, since they can be adapted to any type of production (from conventional production to heat recovery, including nuclear and renewable energy), sCO2 cycles offer very interesting prospects in terms of increased efficiency, flexibility, cost control and reduced environmental impact.

 

All over the world, numerous research projects and demonstrators are being set up, and Europe is positioning itself as one of the players in this area. The number of research projects on sCO2, financed by the European Commission, has been increasing for more than 6 years and demonstrates the dynamics of European academic and industrial actors.

 

Given this fact, the event proposed within the framework of the sCO2-flex project aims to show the versatility of sCO2 cycles in energy production as well as the objectives and results obtained by the actors of these European projects.

In addition to a presentation by the European Commission, 6 projects will present their vision of the potential of sCO2 cycles. They are:

Carbon Dioxide mixtures at the 4th European sCO2 Conference for Energy Systems, Prague

The 4th edition of the European sCO2 Conference for Energy Systems, held virtually on March 23-24, gathered some forty excellent works presented by international authors. The number of attendees and quality of works presented confirmed that the sCO2 community is vibrant and the future of the technology looks bright.

A number of very interesting papers dedicated to CO2 blends triggered the interest of the SCARABEUS consortium:

  • 1 Valencia Chapi, R., Fierros-Peraza, O., Coco-Enríquez, L., Muñoz-Antón, J., Modeling and study of a printed circuit heat exchanger for Brayton power cycles using supercritical CO2 mixtures as working fluid (Universidad Politécnica de Madrid)
  • 2 Ayub, A., Di Marcoberardino, G., Invernizzi, C.M., Iora, P., Advanced thermodynamic power cycles utilizing carbon dioxide based mixtures as working fluids for high temperature waste heat recovery (University of Brescia)
  • 3 Rath, S., Mickoleit, E., Gampe, U., Breitkopf, C., Jäger, A., Study of the influence of additives to CO2 on the performance parameters of a sCO2-cycle (TU Dresden)

These added to two works by University of Seville and City, University of London, presented on behalf of the consortium:

  • Aqel, O., White, M., Sayma, A., Binary interaction uncertainty in the optimization of a transcritical cycle: consequences on cycle and turbine design (City, University of London)
  • Crespi, F., Rodríguez-de Arriba, P., Sánchez, D., Ayub, A., Di Marcoberardino, G., Invernizzi, C.M., Martínez, G.S., Iora, P., Di Bona, D., Binotti, M., Manzolini, G.,  Thermal efficiency gains enabled by using supercritical CO2 mixtures in Concentrated Solar Power applications (University of Seville, Politecnico di Milano, University of Brescia, LEAP)

Different CO2 mixtures were proposed for Concentrated Solar Power and Waste Heat Recovery applications. Rath et al. performed a vast screening of 135 candidates out which five were selected: Krypton, Xenon, Carbonyl sulfide (COS), Propane and Sulfur hexafluoride for WHR systems. For the same application, Ayub et al. studied CO2-Novec mixtures in three different layouts, concluding that a 3 percentage point gain with respect to pure CO2 seems possible. Regarding CSP, Crespi et al. investigated the use of CO2-C6F6 and CO2-TiCl4 mixtures, coming to the conclusion that it is possible for the power block to achieve and even exceed 50% thermal efficiency even under semi-arid boundary conditions, provided that the suitable cycle layout is selected for each working fluid-was achievable. Also for CSP plants, Valencia-Chapi et al. modelled a printed circuit heat exchanger and studied its performance for different CO2 mixtures, noting that heat transfer coefficients of the mixtures were higher than those of pure CO2; this favours lower heat exchang areas. Finally, the turbine of large power blocks running on CO2-C6F6, CO2-H2S and CO2-NOD (non-organic dopant) were studied by Aqel, White & Sayma.

Common to all work was the emphasis on the suitable fluid modelling of CO2 mixtures. In the work of Ayub et al., binary interaction parameters of different CO2 mixtures (Novec 5110, Novec 649, R134a, HFO1234yf and HFO1234ze(E)) were estimated using experimental VLE data from literature and then applying Peng-Robinson with Van der Walls mixing rule to estimate thermodynamic properties. The same fluid model was used by Crespi et al. for CO2-C6F6 and CO2-TiCl4 mixtures. Valencia-Chapi et al. modelled CO2 mixtures using the Aungier-Redlich-Kwong real gas model. Aqel, White & Sayma studied the influence of four different Equations of State and of the uncertainty in the estimates of binary interaction parameters on cycle performance and turbine geometry. Rath et al. use a predictive model to calculate mixture properties based on the best available EoS for the pure components.

In addition to the works by Aqel et al. and Crespi et al., which describe the latest results obtained by the SCARABEUS consortium, a series of works developed by other projects funded by the European Commission (sCO2 Hero and sCO2 Flex) were presented at the conference. Moreover, several interesting topics regarding sCO2 cycle performance, turbomachinery and heat exchanger design and novel sCO2 cycle configurations have been thoroughly discussed. The entire set of presentations and papers are available online in the conference repository (https://sco2.eu/conference-repository/4th-conference-online/) so, if you wish to take a closer look at some of the works, just follow this link and enjoy!

 

Preliminary heat transfer experiments at TU Wien

One of the major goals of the SCARABEUS project is to show the feasibility of the innovative air cooled condenser (ACC) through experiments in Vienna. This heat exchanger is a crucial component in the proposed technology by enabling dry cooling in warm areas where one would typically find Concentrated Solar Power plants.

For down-sizing and thereby reducing the costs, enhanced finned tubes on the inside (CO2 side) will be used. In the course of the design process of Kelvion, experimental measurements at TU Wien are essential to evaluate the heat transfer coefficients on the CO2 side.

To do so, the existing test rig at TU Wien was modified. Originally, in the former project for which the rig was designed and constructed, this was able to perform a full Rankine cycle at a maximum CO2 temperature of 350 °C and a pressure of up to 240 bar. For the heat transfer measurements, maximum temperature and pressure were temporarily reduced, since only the low pressure side is of interest.  After the expansion valve, which represents the turbine, two heat exchangers are now located: the precooler and the test tube.

The test tube is a tube-in-tube heat exchanger of 1 m length. Water was chosen as the cooling medium. In a numerical study, Kelvion determined two types of fins considering number, height, thickness and angle of the fins. There will be three test tubes tested at TU Wien in total:

  • BARE test tube
    • Used as a reference without fins
  • COOLING test tube
    • Fins designed to enhance the heat transfer when cooling down superheated CO2
  • CONDENSING test tube
    • Fins designed to enhance the heat transfer when condensing the CO2

The precooler´s purpose is to specifically control the conditions of CO2 at the inlet of the test tube. The test conditions will cover a range of conditions we expect at the ACC in the future which will show dependencies of the heat transfer on:

  • 2 pressures
  • 3 CO2 mass flows
  • 2 CO2 inlet temperatures
  • 5 values of inlet vapor content

To show the impact of an additive on the heat transfer, the heat transfer of a blend of CO2 with R1234ze will be examined and compared to pure CO2. Based on the results the ACC will be designed.
