Selected papers from the 4th European Conference on Supercritical CO2 for Energy Systems

Abstract

Stable and predictable energy supply, a low ecological footprint and affordability of energy require a mix of energy technologies with thermal energy included. In this context, supercritical carbon dioxide (sCO2) power cycles promise a large development step that will ensure security and flexibility of electricity supply at lower costs with a reduced carbon footprint. In the last decade, extensive research has been carried out to develop knowledge and upscale the technology readiness level of sCO2 power systems. At European level, the European sCO2 Research & Development Alliance aims at providing a platform for exchanging knowledge on sCO2 technologies in the energy sector for academia and industry, as well as at promoting this topic to the wide society. The 4th European Conference on Supercritical CO2 (sCO2) for Energy Systems is one of the initiatives promoted by the EU sCO2 alliance that was held in Prague on 22-26/03/2021. The event brought together more than 100 participants from all over the world with expertise from research to policy development. There were two keynotes and more than 50 podium presentations. All submitted papers were peer reviewed and approved by the conference committee. Further details at www.sco2.eu

This special issue gathers selected papers from the 4th European Conference on Supercritical CO2 in the following research topics related to energy systems: Heat Exchanger and Transfer, Turbomachines and Cycles, sCO2 Applications and Energy Systems, sCO2 Experiments and Loops, Fluid and Material Aspects.
