Linde was involved in the collaborative projects OXYCOAL-AC, ADECOS and COORIVA, which were organised within the framework of the COORETEC (CO₂ REduction TEChnologies in fossil-fuel power plants) programme run by the German Ministry of Economics and Technology.
The OXYCOAL-AC project focussed on developing a CO₂-free coal-burning process for generating power. ADECOS researched solutions for the oxyfuel process. COORIVA was a collaboration between the TU Bergakademie Freiberg, The Linde Group and further industry partners. The project included feasibility studies for a lignite and pit coal-fired IGCC reference power plant to be built from 2015 and equipped with CO₂ separation technology.
