Green Gas Support Scheme

The biggest incentive in the United Kingdom to invest in renewable energy and biogas upgrading has been the RHI – Renewable Heat Incentive. Introduced in October 2011 and growing demand in renewable energy incentives, it was time to review and renew this incentive program. As of 2021 (fall), the RHI will be replaced by the Green Gas Support Scheme, an incentive that focusses on biogas upgrading. It supports biomethane produced from anaerobic digestion (AD) of biomass feedstocks injected into the gas grid. Our biogas specialist can help you with your questions concerning the Green Gas Support Scheme.
