This article refers to the German biogas market and the German law. From a technical point of view, some ideas can certainly be transferred to your country.<\/em><\/p>\n

The expansion of renewable energies in Germany is moving forward. Renewable Energies are, according to the Bundesministeriums f\u00fcr Wirtschaft und Klimaschutz<\/a> (2024), with about 52 % of the gross electricity consumption in the first half of 2023, one of the most important energy sources. The share of renewable energy is expected to increase to 80% by 2030. The Umweltbundesamt (2023) emphasizes that biomass remains the most important renewable energy resource. With various uses across sectors such as heat, transportation, and power generation, the share of biomass in renewable energy is about 53%.<\/p>\n

Furthermore, the Bundesministerium f\u00fcr Ern\u00e4hrung und Landwirtschaft<\/a> (2022) underlines the essential status of biogas for future energy systems in one of its articles, which is based on the energy source’s storable, flexible, and base load-capable characteristics. For 2021, the amount of renewable energy generated from biogas takes up 12.2%; for renewable heat, it is up to 10 %. The positive development correlates with the growing number of biogas plants in Germany since 2000, which numbers about 9.600 now. The substantial force of this development was based on the compensations granted by EEG for gas supply over 20 years. This now-ending period leads to the fact that biogas plants have had to face reliable follow-up concepts from the beginning of the EEG Compensation.<\/p>\n

An economic Operation without federal support systems (EEG) is hardly obtainable<\/strong><\/h4>\n

The question of suitable follow-up concepts for a further economic operation of biogas plants is highly precarious these days. G\u00fcsewell et al. (2023) underline that to this day, the operation of biogas plants in Germany without federal support systems (EEG) is only economically viable under favorable conditions. By developing a guideline, Baumk\u00f6tter et al. (2020) delineate a solid framework for comparing different follow-up concepts in terms of practical applicability for plant operators. The current political discussions are still not clear about the option for a continued compensation period of over ten years. Plant operators can choose alternatives to the EEG to avoid decommissioning.<\/p>\n
