Standortanalyse von biogenem Wasserstoff

The requirements for the electrical grid increase as more renewable energie sources are integrated into the electrical infrastructure. To comply these demands, technologies must be restructured. This also applies to biogas plants, which, under the old regulations, still fed into the grid in baseload mode and now need to be converted to flexible operation. This transition requires investments in infrastructure that must be planned and implemented by the plant operators.
On the other hand, there are innovative processes, such as dark fermentation, that can increase the efficiency of the biogas plant and thus increase the profit of the biogas plant. Investments are also necessary to integrate this method. This means that plant operators considering integrating dark fermentation must bear the costs of restructuring the infrastructure and plant technology for this innovative process. A financial assessment is re-quired to determine whether this amount can be raised and financed.
This paper aims to combine the aforementioned economic topics and create a scenario in which the framework conditions are arranged to the current circumstances. Since the Renewable Energy Sources Act provides various options for remuneration for the amount of electricity fed into the grid, a scenario will be defined and evaluated for each option. The annual revenues and costs will be compared to determine the economic viability. The goal of the evaluation is to assess when a biogas plant is considered suitable for these investments.
The results will be projected onto the dataset containing all biogas plants at the national level to determine which ones are classified as suitable or unsuitable. This will allow to determine the potential for the energy system that dark fermentation can bring.
