Like biofuel. biogas is used as a substitute to mainstream fossil fuels. It can either be fed through the grid and used for heating purposes, or burnt in large power stations and converted to electricity.
It can also be compressed and used to power vehicles. In fact, figures suggest biogas could make up 17% of the UK’s vehicle fuel needs.
Biogas can be created through fermentation or anaerobic digestion of biodegradable products. It was first used in Britain’s gas grid in 2010. Sewage from 30,000 homes was treated and sent back to provide gas.
