It is now possible to buy gas that is 100% renewable under the Green Gas Certification Scheme from two suppliers. Most of the gas is generated from anaerobic digestion (pictured, an AD plant).

Prince Charles was the first customer for the green gas last month, purchasing gas to supply the eco-town Poundbury. Now the scheme has taken on a new registered supplier and two more users.

Ceres Energy has just signed up to become the Scheme’s second registered gas supplier, jockeying with existing sign-up Barrow Shipping to supply green gas. Gas Bus Alliance and Brit European have bought Green Gas Certificates worth a total of 6 GWh of biomethane.

Ciaran Burns, GGCS Certification Manager, said: “We are delighted with the upsurge of interest in the Scheme and the Green Gas Certificates. While Prince Charles’ colleagues were buying green gas to improve the environmental performance of their offices, the latest GGCS customers are reducing the environmental impacts of running a commercial vehicle fleet.”
