Topic

The R&D-Platform „BtG“ pursuits the scientific monitoring and optimisation of the AER gasification technology and focuses on innovative methods to use the high-quality product gas in a poly-generation concept.

Aims

In the frame of this project, innovative methods to generate power, heat and / or SNG (H2) from low rank biomass resources are developed, proven and demonstrated. Hence, project work shall support product realisation and, respectively, commercial launch of an AER demonstration plant. Goals are the prove of feasibility of innovative conversion technologies in order to initiate future demonstration projects. A further overall objective is the installation of a network consisting of research institutes, universities and companies. Further R&D projects dealing with thermo-chemical biomass-to-gas technologies will be acquired and a close cooperation with the operator of the AER gasification plant concerning public relations, marketing and market positioning is envisaged.

Measures

ZSW

The scientific task of ZSW and its partners is to investigate the applicability of mineral-rich biomass resources for AER gasification. Another research topic is the conditioning of AER product gas for SNG production and renewable hydrogen. Further the conception of AER pressure mode will be investigated because pressurised gasification enables higher reaction rates and allows smaller reactors with higher biomass input.

KIT

The Institute of Combustion and Power Plant Technology (IFK) predominantly investigates the applicability of mineral-rich biomass resources (e.g. agricultural waste materials, etc.) from the “biosphere reserve Schwäbische Alb” for AER gasification to enlarge the spectrum of usable types of biomass and to exploit potential biomass sources that are not in competition with food production or heat generation. Gasification trials are operated under AER conditions at the coupled fluidized bed gasification pilot plant of the IFK with selected wood substitute fuels and wood substitute mixtures from the biosphere reserve.

DVWG

  • Evaluation of different methods and pre-selection of the reactor and catalyst system concepts for cleaning the gasification raw gas up to syn gas quality.
  • Construction of a laboratory apparatus to prove the feasibility of a hot gas cleaning concept for SNG production from AER gasification gases experimentally.
  • Screening of catalysts and adsorbents with model gases and evaluation with real gasification raw gases at IFK.
