Potentials of flexible biogas storage and utilization concepts - SYMBIOSIS
The aim of this subproject was to develop more competitive, efficient, and environmentally friendly technologies and pathways in biogas production for the specific region of Baden-Württemberg.
First, using computer-based modeling single components like pumps or columns were put together to get modules such as desulphurization or drying units. These modules were then refined into different systems. For each of the three utilization concepts — combined heat integration and power generation, injection into the natural gas grid, or utilization at filling stations — the best system was identified. Example boundary conditions for these concepts included distances to gas pipelines and the amount of gas-powered vehicles inside an administrative district. In order to map these boundary conditions, already existing biogas plants were registered in a GIS that can incorporate such additional information. Thus, depending on the geographic site, the best utilization concept for biogas and therefore an economically useful und demand-based plant technology was identified.
For years, the institute of Combustion and Power Plant Technology (IFK) has successfully completed projects in the field of capturing CO2 from flue gases and biogas. Chemical scrubbing with amines, amino acid salts (ACE), or alternative solvents are especially considered for the separation of CO2 from flue gases. In the field of biogas, projects are carried out at the IFK where ACE and polymer resins are used to capture the CO2. In the Bioenergy Research Platform supported by the Ministry for Rural Areas, Food and Consumer Protection of Baden-Württemberg, the IFK investigated an innovative biogas upgrading process.
