New project: Flexibilisation of a fermentation plant through coupling with biomass gasification

01/03/2020
 

In January 2020, the joint project "IntenseMethane - process intensification and flexibilisation of a dry fermentation process through biological methanation of hydrogen rich synthesis gas" started.

The aim of the project is to convert hydrogen rich (synthesis) gas from a wood gasification plant (or optionally from electrolysis) into methane in an existing dry fermentation plant for organic waste. The influence of the supplied gases on the biological methanisation as well as the achievable gas yields or conversion rates are to be investigated. In addition to the coupling of an industrial dry fermentation plant with the wood gasifier, the individual process steps are to be optimised with regard to maximising synergy effects and under the aspect of sector coupling. The core of the concept is to adapt and link existing and already established plant technology in such a way that the joint use of plant components creates synergy effects that make decentralised biomass utilisation more effective and economical via the "biogenic methanisation" path. The work of TEER focuses mainly on the biomass gasification system. This includes all conceptual work on plant coupling, the optimisation of the plant for N2-reduced operation and the metrological recording of the input materials and products (especially synthesis gas).

The project is being carried out together with the project partners BEKON Gmbh, LiPRO Energy GmbH & Co. KG and the Chair of Energy Process Engineering at the Friedrich-Alexander University of Erlangen-Nuremberg. The project is funded for three years by the Federal Ministry for Economic Affairs and Energy.
