The working group is concerned with the production of biogenic gaseous energy and carbon carriers by means of thermochemical processes. These conversions open up new fields of application for biomass in the energy sector, industry and transport. In this context, the thermochemical conversion of solid biomass into a CO/H₂ synthesis gas by gasification, the purification and separation of reducing biogenic gases and the synthesis are the subject of the work.

The gas cleaning and separation steps are used not only for synthesis gas from biomass gasification but also for other gases containing biogenic CO₂ and for hydrogen produced from renewable sources. This area of activity includes theoretical and experimental investigations, balancing and evaluations, as well as validation through measurements on plants on a technical scale.

The working group's focus topics:

• Investigation of fuels for their suitability for thermochemical gasification
• Scientific investigation and further development of gasification processes
• Purification,  conditioning and separation of reducing gases
• Membrane-assisted separation and synthesis processes in the gas phase
• Thermochemical supply processes for synthetic biomethane
• Application studies for catalysts with biogenic educts
• Use of biogenic CO₂ in syntheses
• Integration and modularisation of reactors for decentralised concepts
• Overall concepts with synergies in the use of biomass and renewable electrical energy
• Balancing and techno-economic evaluation of concepts and plants
