The Green Gas Certification Scheme (GGCS) tracks biomethane, or ‘green gas’, through the supply chain to provide certainty for those that buy it.
Each unit of green gas injected into the grid displaces a unit of conventional gas. So the GGCS tracks each unit of green gas from its injection into the distribution grid, to any trades, to its sale to a consumer, or group of consumers. It tracks the contractual rather than physical flows to ensure there is no double-counting from production to end use.
The GGCS is run by the Renewable Energy Association’s subsidiary, Renewable Energy Assurance Ltd. GGCS participants oversee the way it is run, on a not-for-profit basis.
The GGCS is a simple and reliable way to eliminate double-counting of registered green gas. It provides certainty for consumers who buy the gas, confidence in the green gas sector and an incentive for gas producers to inject green gas into the grid instead of using it to generate electricity.Follow @GreenGasCert
Any-one involved in the green gas supply chain can take part in the Green Gas Certification Scheme. The key participants are green gas producers who register the gas they’ve injected to the grid, and suppliers and other traders who register gas sale contracts they’ve agreed. See The Scheme for more details of the respective roles of participants in the GGCS.
Each kWh of green gas is labeled electronically with a unique identifier known as a Renewable Gas Guarantee of Origin (RGGO). This identifier contains, for each kWh of gas, information about where, when and how it was produced. When consumers buy green gas the RGGO is their guarantee that the gas is authentic and has not been sold to any-one else. The range of RGGOs is listed on the consumer’s certificate and can be validated here.
To celebrate the success of this market and to showcase project developments, UK Biomethane Day 2015 becomes a two day event, giving biogas producers and developers the chance to meet all the main biomethane industry suppliers and to understand how to take full advantage of the new biomethane RHI tariffs. We are expecting over 300 delegates, with exhibition stands from all of the major suppliers of biomethane related plant. If you are considering biomethane to grid this is the one industry event you cannot afford to miss...

The injection of renewable or “green” gas into UK networks has been growing rapidly – and there are now 28 biomethane to grid projects connected to the gas distribution network, transforming food, brewery and agricultural wastes and energy crops into ultra-clean energy. These plants have the capacity to produce 1.8 billion kilowatt hours of gas per year, enough to meet the heating and cooking needs of around 100,000 homes. Biomethane injected into the gas grid, helps decarbonise gas supply in just the same way as renewable electricity decarbonises power generation...
