In the little village of Nether Stowey, nestled in the Quantock hills, a birthday party was under way in the village hall.
It is an unusual cake, for a quirky celebration. The village’s gas plant has turned 10, so locals made a cake shaped like the two domed gas tanks.
The primary school children who came to the party have been raised almost entirely on gas from the nearby plant.
This one is not fed with cattle manure, but human food waste. This is collected by local councils and fed into a digester, and once again the bacteria get to work.
The cake is part of a campaign. Wales and West Utilities run the national gas grid in Somerset, and the company is keen to get more biomethane produced.
Already the West Country is a “hotbed for anaerobic digestion and biogas”, according to Matt Hindle, head of Net Zero at Wales and West.
There are 20 biomethane plants in the south-west of England, but the firm wants more.
“We think biomethane could be a really significant part of our gas mix and could work with hydrogen, and electrification, as part of a whole system approach to decarbonisation of the heating system,” said Mr Hindle.
