TOTeM 52, entitled ‘Oxy-fuel combustion and CCUS’, was held on 27-28 May 2026 in Essen, Germany. Organised by the IFRF French Committee and hosted by GWI, the event attracted close to 60 participants from some 12 countries – mainly from Europe but also including participants from China and Japan. Industrial organisations represented exactly half of the attendees, reflecting the important role of both IFRF and GWI in providing a forum for both industry and academia to interact on energy-related topics. The event included 4 keynote presentations, 13 posters and 16 oral presentations, all of which are included here for your perusal.
