The aim of the research project is to use existing gas (pore) reservoirs as natural bio-reactors. The methanation process and storage take place naturally in underground pore reservoirs. This represents a huge source by potentially providing the urgently needed flexibility, which renewable energy sources currently lack.
Hydrogen and existing carbon dioxide injected into the reservoir convert into methane by a microbiological process. This enables the creation of a sustainable carbon cycle. Laboratory tests, simulations and a scientific field test at an existing RAG reservoir will be carried out in collaboration with a group of project partners. A further objective is to test whether the outcomes can also be achieved at many other reservoirs all over the world. The striven results are therefore of outstanding importance for a successful energy transition.
