Power-to-gas

Power-to-gas: costly – but not doing it is costly too. For those of you who have been following developments in power-to-gas in Europe, the new report by Martin Lambert of the Oxford Institute for Energy Studies, Power-to-gas: linking electricity and gas in a decarbonizing world?”, will probably not contain much news. But for those of you who have not been paying much attention and who would like to catch up, it presents an excellent overview of the projects that are taking place across Europe and of their economic potential, as far as current knowledge goes (which is not that far). As Lambert reminds us, natural gas demand will “need to decline at an accelerating rate” after 2030 “if carbon reduction targets are to be met” in Europe. “If existing natural gas infrastructure is to avoid becoming stranded assets, plans to decarbonise the gas system need to be developed as a matter of urgency in the next three to five years, given the typical life expectancy of such assets of 20 years or more”, notes Lambert. There are three alternatives to natural gas being developed by industry at this moment: Large scale conversion of the gas network to hydrogen, with hydrogen production by methane reforming with carbon capture utilisation and storage (for example, the UK’s Leeds H21 project4 ). Greater use of biogas and/or biomethane (discussed in an earlier OIES report). Production of hydrogen or renewable methane via power-to-gas. The new report focuses on power-to-gas (i.e. production of hydrogen or methane on the basis of renewable energy), but Lambert warns that “the commercialisation of power-to-gas technology is at a very early stage of development, with a limited number of pilot and demonstration plants in operation or under development.”
