Abstract

Already in the 1990s, strong decrease of hydrogen content in town gas (45-50% H2, 20-25% CH4, 8-12% CO2, 7-11% CO and 8-10% N2) was observed in the underground gas storage. It was followed by an increase in the methane concentration. The temperature rise and the presence of unusual compounds were noted. The presence of methanogenic archaea, which appeared to be responsible for changes in gas quality, was also confirmed. A detailed survey was related to the planned switch to natural gas storage instead of town gas. At the same site where natural gas is currently stored, we and the authors of the original study conducted analyses with the aim to find out whether this natural environment could be used to the production of biomethane throughout Power to Methane technology. The observed results confirmed the occurrence of microbial methane. Water sampling has confirmed the suitable physical and chemical properties of groundwater for biomethane production.
