Planned results:
In the future, substrates for biogas production will be provided mainly by residual materials. Residual materials with TS>30 %, e.g. horse manure, cannot be used in wet fermentation (TS<15 %) without a complex pre-treatment due to their nature. Especially for small, decentralised residual material quantities in rural areas, the use of small plants up to a rated output of 75 kWel is a technically sensible solution. Currently, small wet fermentation plants are primarily designed for manure utilisation. In these digesters the use of solid residues is possible to a limited extent. From a technical point of view, the more suitable alternative of solid fermentation (TS>20 %) currently has uneconomical electricity production costs of >20 cents/kWhel for small plants.
The aim of the project is to develop a solid fermenter suitable for stackable residues. At the end of the project, the investment costs should not exceed the amount of 8,000 €/kWel, in order to enable electricity generation costs of <15 cents/kWel for small plants. This is 25% lower than the current EEG regulations for small plants. The aim is low construction costs, low transport and storage costs, regional use of residual materials and implementation in a kind of builder-owner model. The construction and operation of a prototype (TRL 6) under real operating conditions will provide project planning and operating experience. During operation, optimizations based on operating experience with different substrates and operating conditions (flexible and fixed gas and energy production, partial and full loading, etc.) are incorporated. The need to adapt existing legal regulations is determined along the entire project planning chain. If the economic and technical feasibility is proven, a plant with TRL 8 is expected at the end of the project and subsequently brought to final market maturity by the participating SME.
