Experts say that renewable gas will be available to buy via the grid in the next two to three years.
According to the Anaerobic Digestion & Biogas Association (ADBA), there are 20-30 schemes in the pipeline to inject gas in to the grid from organic waste materials.
This will be available on the ‘green gas’ tariff in the same way that renewable electricity is available to businesses and households.
Addressing a meeting of the Major Energy Users Council recently, energy demand manager at National Grid, Marcus Stewart, hailed biomethane as ‘the most deployable solution for renewable heat’. He also said “The opportunity is significant. Look out for renewable gas: it’s coming.”
Chief executive of the ADBA Charlotte Morton said the UK could produce up to 40TWh a year worth of biogas, adding “It can be scaled up quickly and relatively cheaply.”
Anaerobic digestion is growing rapidly, but government support is needed to help other sources, she said, in particular the gasification of industrial and municipal waste.
