Project description:

B2G – Innovative Generation of Gaseous Fuels from Biomass

Within the B2G project, an innovative method for the optimized material and energetic use of biomass to produce gaseous fuels such as synthetic natural gas (SNG) or hydrogen will be developed and evaluated. The considered conversion processes are thermochemical conversion by gasification and bio-chemical conversion by fermentation. It is a poly-generation 'concept sought by the main products SNG and hydrogen as well as recyclable by-products such as heat, electricity, alternative fuels and fertilizer. A broad flexibility in input materials is sought and alongside anaerobically fermentable, moist 'biomass also lignocellulose, dry' biomass will be used.

On the IIP sub-processes are evaluated economically and ecologically and a meaningful connection of the individual process steps are identified. The overall concept is to be evaluated by calculating the net energy efficiency, the CO2 balance and through a comparison with other biomass utilization paths. Then, by integration into the overall system, a power system analysis will highlight the most promising strategies, taking into account long-term development of the entire energy system and raw material procurement.
