In order to establish the energetic use of biomass permanently in the existing energy system, the DBFZ develops various concepts for the economically viable, ecologically harmless and socially acceptable energetic use of biomass. The aim is to analyse potential areas of conflict between the various objectives pursued with the expansion of bioenergy at an early stage and to develop forward-looking design approaches. Issues to be addressed in this context include integration into a changing energy system, improving energy efficiency, avoiding competing uses or avoiding emissions to soil, water and, in particular, the air. With the work of the DBFZ, the knowledge about the possibilities and limits of an energetic use of biomass is to be expanded overall and the outstanding position of Germany as an industrial location in this sector is to be secured.

Additional Technical Information:
The DBFZ's research biogas plant (FBGA) complements the spectrum of our application-oriented research. The dimensioning of the biogas plant allows experiments to be carried out on a semi-industrial and industrial scale, therefore ensuring good transferability of the results into practical application. The FBGA was planned and built to be technically flexible and open for the addition of up- and downstream aggregates, e. g. for substrate pre-treatment or digestate processing. Being extensively equipped with online measuring probes and accompanied by analyses in DBFZ´s own analytical lab, proper process control can be assured.
In the main, the FBGA consist of the following tanks:
- 2 CSTR type reactors with a reactive volume of ~ 190 m³ each
- A CSTR reactor with a reactive volume of 50m³
- A plug-flow digester with a reactive volume of 50 m³
- A post digester
- Digestate storage
- Manure storage
The digestion stages can be operated at either mesophilic or thermophilic temperature level. Within the FBGA, gaseous and liquid streams can be redirected at will.
For biogas utilisation, a CHP engine with an electrical rated capacity of 124 kW and an emergency flare are available on site.
