In 2016, about 50% of the German heat demand was covered by natural gas. Only approx. 13% of the overall heat was provided by renewable energies. This leads to high dependencies on natural gas and uncertainties regarding future security of supply and prices. In order to reduce those issues, numerous technologies aim to produce substitutes for natural gas from renewable energies:
- Biomethane through the treatment of biogas
- Substitute Natural Gas (SNG) by methanation of synthesis gas from thermo-chemical conversion of ligneous biomass
- Hydrogen production by use of renewable electricity (Power-to-Hydrogen, PtH) as well as its conversion to synthetic natural gas (Power-to-Methane, PtM)
The project "SustainableGas" aims to simulate possible market scenarios for the integration of those renewable gases into the German gas market until 2050. A special focus is laid on local environmental and social structures which are integrated additionally to the energy economics into the model in cooperation with project partners from LMU Munich and FAU Erlangen-Nuremberg.
