“…Another issue regarding the "post-FIT"-phase is the question of whether a retrofitting to bio-CH 4 production would be the most profitable choice. Other potential business models, such as heat, could eventually generate comparatively higher revenues and many biogas plants have considerable potential in this segment [35]. In order to identify the plant-specific favorable option the relevant opportunity costs need to be assessed in more detail.…”

Background The German energy transition has entered a new phase and one important aspect is the question, to what degree the gas sector could be supplied with so-called “green” gases, i.e., gases from renewable sources. This paper focuses on the potential of domestic methane from biological origin (bio-CH4) until 2030 that is estimated with two different methods. The comparison of the results provides a consolidated estimate. Methods In a bottom-up approach, a GIS-based cluster analysis was undertaken to estimate the potential on bio-CH4 from the existing cogeneration biogas plant (BP) stock. In a top-down approach a meta-analysis of GHG-reduction scenarios with respect to bio-CH4 was performed. The meta-analysis was also extended to methane from renewable electricity (e-CH4) since the BP stock may play a role in the provision of CO2. Further, it included the year 2050 (the target year for most scenario studies) as well as issues like energy imports. Results The bottom-up approach yields a potential of 24.9 TWh of bio-CH4 for 2030. This is well within the range of the top-down analysis of 11–54 TWh (average: 32.5 TWh) for that year. In some scenarios values for e-CH4 where considerably higher, especially with respect to 2050, but in these studies the sources—including the CO2 sources—are either not explained at all or they are due to imports of e-CH4 in combination with direct air capture (DAC) rather than biogenic sources. Concerning the regional dispersion, the bottom-up analysis shows that the largest potentials (53% or 905 of the biogas plants) are located in the northern part of Germany, more particular in Lower-Saxony, Schleswig-Holstein, Mecklenburg-Western Pomerania. These represent 54% or 602 MW of the installed capacity of the clusters. Conclusion The consistency of the outcomes of the two methodologically very different approaches may be called the main result of this research. Therefore, it provides a consolidated analysis of the potential for domestic supply of bio-CH4 in 2030. Furthermore, the amount corresponds to 2.7–3.5% of the German natural gas consumption in 2018. Taken bio-CH4 and e-CH4 together it corresponds to 7.2–8.0%.

“…Im Gegensatz zu anderen erneuerbaren Energieträgern hat Biomasse den Vorteil, dass sie fossile Brennstoffe direkt ersetzen kann. Im Kontext der deutschen Energie-und Wärmewende spielt Bioenergie eine zunehmende Rolle, trotz erheblicher Nutzungsund Flächenkonflikte (Pehlken et al 2016;Steubing et al 2020), auch vor dem Hintergrund internationaler Bioökonomiestrategien (Lago et al 2019) und des seit 2014 weitgehend stagnierenden Ausbaus von Biogasanlagen (Purkus et al 2018). In den letzten Jahren ist die Nutzung von Bio- masserückständen und -abfällen stärker in den Fokus gerückt, denn sie gilt im Gegensatz zum Energiepflanzenanbau als nachhaltiger und weniger konfliktbehaftet (Pfeiffer und Thrän 2018).…”

ZusammenfassungBioenergie ist im Rahmen einer nachhaltigen Energiewende von zentraler Bedeutung. Im Vergleich zu anderen erneuerbaren Energieträgern bietet Biomasse den Vorteil, dass sie fossile Brennstoffe direkt ersetzen und bei Bedarf für die Umwandlung in Wärme, Strom und Kraftstoffe gespeichert werden kann. Dementgegen stehen erhebliche Nutzungs- und Flächenkonflikte des Energiepflanzenanbaus und ein seit 2014 stagnierender Ausbau von Biogasanlagen. Als konfliktärmere Alternative gilt die reststoffbasierte Bioenergieerzeugung in Kombination mit dezentralen Nutzungsstrategien, diese stößt in der Praxis allerdings auf erhebliche Umsetzungsbarrieren. Dieser Beitrag stellt Ergebnisse eines transdiziplinären Verbundforschungsprojekts vor, welches in Nordhessen kommunale und regionale Handlungsoptionen für eine optimierte energetische Bioenergieerzeugung untersucht hat. Zentrale Erkenntnisse zeigen, dass eine verlässliche Bewertung von Biomassepotenzialen die Einbeziehung von regionalen Wissensbeständen erforderlich macht. Ein erheblicher Anteil der regionalen Biomassepotenziale ist derzeit in stark fragmentierten Nutzungspfaden gebunden, die allerdings aus ökologischer Perspektive und vor dem Hintergrund steigender CO2-Bepreisung einer Überprüfung bedürfen. Für eine Optimierung von Biomassenutzungspfaden zeichnet sich ab, dass vielversprechende Ansätze vor allem durch interkommunale Kooperationen erreicht werden können.

“…Here, one important contribution deals with combined heat and power production from biomass as one way to efficiently provide renewable heat. Likewise, the gross quantities as well as the economically viable potential of Germany's current bioenergy plant stock is investigated from the viewpoint of supplying renewable heat [6]; whereas, another article focusses on the selection process of different fuel types in detail, where technical aspects such as production, utilization and handling are evaluated by means of a thermodynamic analysis. Based on this analysis, the ecological and economic aspects are assessed to yield a set of recommendations of suitable synthetic transport fuels produced in decentralized plants with CO 2 supply from biogas plants [4]; and a third article in this collection quantifies the role that biomethane produced from straw could potentially play in the transport sector.…”
