The Spanish government adopted a royal decree last week to establish the system of guarantee of origin for gases coming from renewable sources, such as green hydrogen, biogas or biomethane, which will allow marketers and consumers to differentiate themselves from gas of fossil origin.
The system will function similarly to the scheme for renewable electricity, with a guarantee issued for each megawatt-hour of 100% renewable gas produced, together with information on where, when, and how the gas was produced, according to the Spanish Ministry for the Ecological Transition and the Demographic Challenge.
