Customer case study: Future Biogas
Future Biogas gets grid-ready with propane enrichment
Turning agricultural waste into gas for the national grid
A Future Biogas anaerobic digestion (AD) plant in Norfolk is generating enough grid-ready biogas to heat 4,500 homes – thanks to simple, reliable and cost-effective propane enrichment from Flogas.
With enough capacity to process 4,000 tonnes of organic waste material at any one time, Future Biogas’s Methwold AD plant was the biggest facility of its kind in the country when built. It uses locally-sourced agricultural waste and purpose-grown energy crops to generate high-quality biogas, in a 45-day process. After production, the biogas – which takes the form of pure methane – undergoes propane enrichment to upgrade it and ensure it is suitable for injection into the national gas grid.
When developing the site, Future Biogas needed to find a propane supplier that could meet its exact requirements, ensuring optimum system performance and long-term gas-to-grid success.

Optimum performance and long-term success
Having worked together on several biomethane projects in the past, Future Biogas approached industry leader Flogas for a bespoke, turnkey propane enrichment solution.
Neil Bushell, Head of Engineering at Future Biogas, says: “The success of Methwold is a prime example of our strong working relationship: we rely on Flogas to handle the propane enrichment, so we can concentrate on generating first-rate, grid-ready biogas.”
Flogas Service Excellence
Turnkey propane injection system
The Flogas project management team specified, designed and installed a complete propane injection system to enrich the biomethane produced at the Methwold plant. The system comprises a propane injection skid (or vapouriser) and six propane storage tanks.
It is backed by dependable, ongoing LPG supply from Flogas’ well-established national delivery network. Now fully up and running, the Methwold plant consistently delivers high volumes of gas back to the grid, and has also registered to receive ongoing tariff payments under the government’s Renewable Heat Incentive (RHI).
We’re very proud to have provided a custom-designed propane injection system that not only allows the Methwold plant to generate enough grid-ready biogas to heat thousands of homes, but also means it is eligible for ongoing commercial returns through the RHI.

A long-term partnership
Greg Brown, National Account Manager at Flogas, says: “Here at Flogas, propane is our speciality – and we understand that without effective enrichment, biomethane simply can’t go to grid. The UK’s biogas industry has gone from strength to strength in recent years, and companies like Future Biogas – whose plants are equipped to supply high-quality gas to the grid – have an even brighter future ahead.”
