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.
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.
Biomethane Day is becoming Green Gas Day for 2019. As usual it will be a great place to network and get up to date with what's happening in the biomethane sector, but it will also be looking beyond the horizon at other types of Green Gas...
