Vision 2050+. The Role of Biomethane in a Decarbonized WorldSession
The New Energy Mix
The European Union wants it, and Germany has also recently committed itself to reach climate neutrality by 2050. But the 2050 climate strategy poses many questions: How can competitiveness and employment opportunities be maintained in structurally weak regions? What will the transport sector of the future look like? What are the energy sources of the decarbonized world? The German government has set the bar high – anything that is not 100 % climate neutral should no longer play a role by the middle of this century. Biomethane is currently seen as a transitional solution. But what is overlooked is that biomethane can cause climate-positive emissions and a positive greenhouse gas balance through negative emissions – all whilst being able to sustainably secure jobs in agriculture. This presentation will give a brief review of the development of biomethane as a fuel and take stock of the current situation. The main focus of the presentation is to look at the role of biomethane in a decarbonized world. For this purpose, we will first discuss the relevant components for the calculation of biomethane’s potential for greenhouse gas reduction and its current conditions. Then, these components will be recalculated under the premise of a decarbonized world, thus showing how biomethane can even achieve negative emissions and remove CO2 from the atmosphere. Following this, the results are put into the context of 2050. What role do renewable gases play according to various studies, and which assumptions about biomethane should we question? Finally, we will provide an outlook on the structural and economic aspects of decarbonized renewable gases and analyze how, under these new conditions, a circular economy can strengthen agriculture and reduce the gap between urban and rural spaces.
