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. To achieve this, green hydrogen (produced from solar or wind power and water) is injected into an existing (porous) natural gas reservoir together with carbon dioxide. Naturally occurring microorganisms will then convert these substances into renewable gas which can be stored in the same reservoir, withdrawn as needed at any time, and transported to consumers via the existing pipeline network.
