Future Biogas Produces 680 Gigawatt-Hours of Biogas a Year Across 11 Sites
Key Facts
Future Biogas produces about 680 gigawatt-hours of biogas a year across 11 sites, according to 3i Infrastructure’s portfolio page. 3i describes the company as one of the UK’s largest developers of anaerobic digestion facilities and biogas producers. The figures come as the company expands its portfolio of gas production facilities, which includes operating projects and others that have received planning approval. 3i said Future Biogas outperformed expectations during the year. It attributed this to higher gas export volumes and improved gas yields at the company’s owned facilities.
One earlier milestone in building the portfolio came in 2024, when Future Biogas announced an agreement to acquire a majority stake in a portfolio of 6 anaerobic digestion facilities from JLEN. The facilities had combined gas production of 333 gigawatt-hours, according to the announcement. The company also put the deal’s value at 68.1 million pounds sterling. Future Biogas said it had developed 5 of the 6 facilities and operated each for an average of 8 years before the agreement. This positions the company as both operator and developer, alongside its role in expanding the portfolio.
On operating conditions, 3i said lower wholesale gas prices during 2025 did not fully flow through to performance. It said near-term hedging across the portfolio mitigated the impact of falling prices. In contrast, higher gas export volumes and improved gas yields supported Future Biogas’s results during the year. This is part of 3i’s explanation for the company’s outperformance. The portfolio page did not specify the increase in earnings or the scale of the hedging impact.
Operating developments included Future Biogas’s acquisition of the Burton Agnes facility in East Yorkshire, which was completed in February 2026. The facility produces about 40 gigawatt-hours of biomethane a year, according to 3i Infrastructure. The company also said the Gonerby Moor facility had reached full operating capacity. The facility is linked to a 15-year gas sales agreement with AstraZeneca. 3i added that gas injection rates in recent months had exceeded budget.
The company is continuing to develop new projects alongside operating its existing facilities. Two new anaerobic digestion projects received full planning approval during the 6 months before 3i’s 2026 announcement. The approvals brought the total number of sites with planning approval to 4. This gives the company a pipeline of projects that could support future capacity expansion, in line with the development path announced by 3i. The announcement did not specify when construction on the two projects would begin or when they would enter operation.
The UK government is considering support for the biomethane sector beyond 2028 and ways to address barriers to investment, according to a roadmap update published in July 2026. The update links this to an assessment of biogas’s role in the energy system. Meanwhile, the Green Gas Support Scheme provides financial incentives for new biomethane plants using anaerobic digestion, according to Ofgem. Under the scheme’s current timetable, the window for new applications in the first phase closes on 31 March 2028. These dates form part of the regulatory framework within which the sector’s projects operate.
