The Underground Sun Conversion Testbed is a facility to manage methanation of renewable energy in combination with inter-seasonal energy storage - both taking place in a depleted natural gas reservoir.
We inject H2 and CO2 to a depleted natural gas reservoir. There a microbial process takes place, converting those substrate gases to methane and water. Our pending research objective is to flexibilize the process in terms of substrate gas quality as well as the acceptability of off-stoichiometric gas mixtures. The latter seems feasible because of the large available storage volumes in natural gas reservoirs. This leads to an USP towards other methanation technologies.
The Testbed facility was put in operation in 2018. In a previous facility at the same location the interseasonal storage of hydrogen (-admixtures) was tested successfully.
