Synergistic Advanced Carbon Capture Technologies for ConvERsion of Industrially Emitted CO2 to sustainable Production of biofuels and chEmicals

STEROPE integrates advanced Carbon Capture and Utilisation (CCU) technologies with innovative conversion processes to establish a circular economy model. By leveraging cutting-edge membrane and catalytic systems, it enhances the efficiency and scalability of CO2 capture and conversion into renewable e-fuels under real-world conditions. The project targets significant GHG emissions reduction and fossil energy displacement, aligning with the EU’s climate neutrality goals through cost-effective CO2 valorisation, green hydrogen integration, and energy optimisation.STEROPE demonstrates industrial symbiosis by deploying its prototype system within a refinery, enabling resource sharing and reuse. The project advances CCU technologies to deliver a first-of-a-kind TRL 7 system capable of producing e-methanol, e-DME, and sustainable aviation fuels (e-jet), offering viable decarbonisation solutions for hard-to-abate industries.The initiative develops and integrates three CCU units, which will be installed and tested at the Eleusis refinery (Greece) as part of a demonstration plant. The DEMO including the three prototypes will be integrated into the regular operation activities of the refineryA digital twin approach will enhance operational efficiency and optimise renewable e-fuel production. To ensure market readiness, STEROPE includes end-use testing of e-methanol and e-jet for compliance with shipping and aviation sector requirements, guaranteeing performance, safety, and regulatory approval.A comprehensive LCA and TEA will evaluate environmental and economic feasibility, while stakeholder engagement will drive market adoption and policy alignment. By fostering industrial symbiosis and innovative business models, STEROPE accelerates the transition towards a circular, low-carbon economy.
