The Institute of Combustion and Power Plant Technology of the University of Stuttgart has been involved in research activities related to combustion and gasification of solid, liquid and gaseous fuels for over 50 years. Thanks to numerous European, International and national projects, great experience and know-how have been collected in clean combustion technologies, carbon capture technologies and utilisation of solid fuels such as coal, biomass and solid recovered fuels. The knowledge gathered on different combustion technologies over the years will be a great asset to this project in order to retrofit the firing system for low- to zero-carbon fuels. USTUTT has vast experience in project coordination and management in national and international projects such as Oxyburner, BioxySorb, AC2OCem, etc. USTUTT will therefore coordinate the GreenDEALCO2 project and will lead WP6 on management, coordination and dissemination.

USTUTT has been strongly active in experimental activities on the combustion of different biomasses and solid recovered fuels for their utilisation as alternative biofuels for power and cement industry. The outcome and experience of previous and ongoing projects on solid and gaseous fuel combustion can be exploited in this project and serve as a basis for future activities. This extensive results exploitation will support GreenDEALCO2 to formulate and design the most cost- and energy-efficient options for retrofitting end-of-life coal power plants using gaseous or solid fuels in WP1.

Experimental facilities for combustion and gasification are available with capacities ranging from 15 kW to 500 kW. USTUTT in WP1 will modify and adapt the 20 kW electrically heated reactor to investigate the combustion of H2/SNG and alternative energy carriers of Si and NH3 to bring the latter technologies to TRL 5. The technical-scale facility of 20 kW has high fuel flexibility and is suitable for parametric studies. The temperature along the reactor length can be adjusted with the help of five heating elements, enabling reliable investigations of temperature-related combustion. Temperature and profile measurements of the flame and flue gas emissions as well as solid particle sampling are possible along the furnace via a movable sampling probe.

USTUTT will support the retrofittability studies in WP2 and will formulate suitable scenarios depending on the boundary conditions of selected plants and will evaluate the impact of new fuel on the plant performance. USTUTT will also be involved in WP2 to investigate the use of stranded assets for power-to-fuel integration and will perform experiments on oxygen-enriched combustion for waste-to-energy plants, where the oxygen by-product of electrolysis is proposed to be used in the waste-to-energy plant.
