Gas Bus Alliance and Brit European have both become the latest recipients of Green Gas Certificates.
While Ceres Energy has signed up to join existing member Barrow Shipping as a registered gas supplier for the scheme.
Both Gas Bus Alliance and Brit European represent a combined total of 6 GWh of biomethane and have purchased the certificates in order to progress their commitment to operating sustainable transport fleets running on compressed natural gas (CNG).
The first two Green Gas Certificates were presented to the Duchy of Cornwall and the Office of the Prince of Wales last month.
Green Gas Certification Scheme certification manager Ciaran Burns 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. This demonstrates the variety of applications for both biomethane as a fuel and for the Green Gas Certification Scheme itself.
“We are also very pleased to welcome Ceres Energy as the GGCS’ second registered supplier. We look forward to welcoming more producers, suppliers and customers into the scheme as word spreads in the coming months.”
Meanwhile, Barrow Green Gas, which is the trading name for Barrow Shipping, has announced that it is to form a biomethane producers club to share technical, operational and commercial information to optimise plant efficiency and financial return for biomethane producers.
