Final COMPASsCO2 Workshop

Workshop Overview
As recalled by the Green Deal Industrial Plan of the European Commission (1), the next decade will be crucial to put the EU on the right track to reach 2050 carbon neutrality objectives. New markets will have been created, breakthrough clean technologies will have been innovated, developed, and brought to market, and our energy systems transformed. Research, development and innovation are key to enable a reliable emission pathway towards sustainable industry, as recalled also in the SPIRE (2) Roadmap. The Horizon 2020 COMPASsCO₂ project intends to contribute to sustainability by focusing on a series of key innovations in terms of renewable energy system integration, material durability and process improvement, in line with the SPIRE action concepts.
The COMPASsCO₂ project has been dedicated to advancing the development, integration, and optimization of supercritical CO₂ (sCO₂) power cycles, a promising technology for next-generation energy systems. As we reach the final stage of this initiative, this workshop provides a platform for researchers, industry professionals, and stakeholders to exchange insights on the latest advancements and challenges in the field.
The thematic sessions will focus on key aspects of sCO₂ technology, including system efficiency, material durability, component development, and industrial applications. Discussions will explore cutting-edge research on the thermodynamic performance of sCO₂ cycles, addressing the critical challenges associated with heat exchangers, turbomachinery, and cycle optimization. In particular, attention will be given to high-temperature materials, coatings, and advanced manufacturing techniques that enhance the reliability and efficiency of sCO₂ components under extreme operating conditions.
By facilitating discussions on these topics, the COMPASsCO₂ final workshop aims to consolidate the knowledge gained throughout the project, identify future research directions, and support the transition towards high-efficiency, low-carbon power generation solutions. This event serves as a crucial milestone in the broader effort to accelerate the adoption of sCO₂ technology in industrial and energy applications.
