Alternatives to natural gas: the legal framework on synthetic natural gas and biomethane

For centuries, natural gas has been one of humanity’s main energy sources. The gas sector is still heavily reliant on natural gas production; however, as natural gas fields contain only a finite quantity of gas, its continued extraction is leading to the resource’s depletion. Furthermore, natural gas production has become a subject of debate, with many considering continued utilisation incompatible with the achievement of international and European climate goals. The need for alternative gases that are less damaging to the environment is becoming increasingly evident. Biomethane has shown itself to be a reliable alternative to natural gas, and if sourced and manufactured responsibly results in no new CO2 emissions. Another alternative, hydrogen, can, through the process of methanisation, be converted into synthetic natural gas (SNG). This chapter discusses the legal aspects of the production and use of biomethane, hydrogen and SNG.
