Project description
This joint project is a follow-up to the successfully completed WeMetBio project. Part of the project is the construction of a plant for biological methanation using the trickle bed process to produce bio natural gas from biogas, wind turbines are to be used to produce hydrogen as well as extensive thermal and material integration in the energy network at the Nordhackstedt (SH) site, which was found to be suitable.
The project includes the planning, construction and operation of a biological methanation plant including electrolysis, its economic, ecological and technological evaluation in the local network and the emission of the biomethane with a variety of optional utilisation paths. The aim of the project is to prove that biological methanation in the trickle bed process is cost-effective, simple, robust, reliable and has a GHG reduction potential and therefore can be used as an add-on technology for the continued operation of existing biogas and wind power plants that have fallen out of the EEG (German renewable energy law) subsidy scheme. Thus, it can substitute fossil natural gas partially at least and improve the GHG balance of gas users.
Another objective is to utilise the so-called surplus electricity from wind power plants and to produce additional methane and heat. This approach contributes to increasing self-sufficiency with renewable energy sources in the regional network.
Objectives
- Construction of a plant for biological methanisation
- Integration of energy from renewable sources
- Proof of economic viability and sustainability
- Substitution of fossil energy
