The demand for synthetic, climate-neutral energy sources such as hydrogen and its derivatives could increase in the future energy system. The exact mix of energy sources is currently still uncertain. One possible energy source could be synthetic natural gas (SNG).
SNG is a substitute for natural gas and can be used in current infrastructures and end applications without the need for technical adaptation. This could enable short-term integration into the energy system. Thanks to the existing natural gas infrastructure in Germany, SNG offers the potential for avoiding investments and emissions.
SNG is produced by methanation from hydrogen and CO2. So far, methanation has only taken place in individual demonstration projects. In addition, providing CO2 in various processes still has high costs and a low technology readiness level. The costs of CO2 provision and the regulatory framework conditions influence the future economic use of SNG compared to other climate-neutral energy sources such as hydrogen.
