Collaborative project: Demand oriented storage of fluctuating renewable (wind) energy by integrating biological methanation (trickle bed process) in the power system of Schleswig-Holstein - Feasibility study at the locations Schuby and Nordhackstedt (WeMetBio)
Project
Project code: 2219NR134
Contract period: 01.04.2020
- 31.03.2021
Budget: 87,945 Euro
Purpose of research: Experimental development
Keywords: biogas, biomethanation, processing stability, renewable ressources
The overall objective of the project is the integration of an innovative pilot plant for bio-methanation into the energy network of biogas, biomethane plants, wind turbines and methane supply into the natural gas grid. The feasibility study aims to identify efficient and economical concepts, decision-making and integration at the selected project locations Schuby and Nordhackstedt (Schleswig-Holstein). For the success of the energy transition, the system integration and coupling of various renewable energy sources, including their storage and transport, represents a crucial challenge. At the same time, both biogas and wind turbine operators face the challenge of developing economic post-EEG concepts for existing plants. Due to its geographical location and favorable conditions, within the WeMetBio project a feasibility study is aspired. It aims on the sector coupling of wind turbines with fluctuating electricity and biogas / biomethane plants in view of the feasibility of the technology and its transferability into efficient and economic rural areas. Practical partners are the biomethane plant Schuby and the biogas plant of Nissen Biogas GmbH & Co. KG. There are various CO2 sources available for bio-methanation. The reaction partner H2 is provided by means of electrical energy of the wind farm Nordhackstedt-Ost by electrolysis. For the realization, the construction of a trickle bed reactor in a pilot scale and integration into the plant inventory is planned on site. Decisive advantages of this patented process are the high methane concentration combined with low energy consumption, process stability and on-demand controllability of the operation to the minute. After virtual passage through the natural gas grid, efficient use can be made for electricity generation, as a source of heat, as a chemical raw material or as fuel.
