The Prince of Wales has opened an anaerobic digester and biomethane plant in Dorset.
The plant at Rainbarrow Farm, Poundbury, is the UK’s first commercial scale plant to inject renewable biomethane directly into the gas grid.
It is owned and operated by J V Energen, a joint venture between local farmers and the Duchy of Cornwall.
Anaerobic Digestion & Biogas Association chief executive Charlotte Morton said the plant demonstrated the ability of the AD industry to deliver large volumes of green gas into the grid for use today.
“Biomethane, one of the few sources of truly low carbon and renewable gas, is strategically important for the UK economy and energy markets, delivering on the government’s key objectives for both energy security and economic growth.
“The Poundbury plant demonstrates that biomethane to grid technology works at commercial scale now. With 10 more plants scheduled to come online in the next 12 months, biomethane from AD should be recognised as the serious commercial energy proposition that it is.”
Biomethane is formed from the decomposition of organic matter under controlled, anaerobic conditions, which produces the gas alongside a renewable fertiliser. It is extremely low carbon, and once upgraded is close to pure methane and very similar to natural gas.
