Grosvenor Green Gas

Heating homes with recycled agricultural waste

Grosvenor Green Gas is our new initiative to produce National Grid‑ready biomethane from recycled agricultural waste, supplying enough renewable gas to heat around 6,000 homes a year, strengthening the UK’s energy resilience.

Building on a track record of innovation and one of the lowest carbon footprints in UK milk production, the project involves investment in an anaerobic digester and integrated biogas upgrading facility, reinforcing our commitment to commercial sustainability and environmental responsibility.

Anaerobic digesters use microorganisms to break down agricultural waste, producing biogas and digestate – a high-quality organic fertiliser that also enhances soil health. The biogas is upgraded to make biomethane, which is injected into the National Grid, and the fertiliser is used on the farm, reducing reliance on resource‑intensive inorganic fertilisers.

We estimate that the facility will produce in excess of 72 GWh of biomethane per year from up to 170,000 tonnes of manure, avoiding around 8,500 tonnes of CO₂ equivalent emissions annually.

In addition to enabling the production of renewable energy, anaerobic digestion improves air quality by capturing pollutants such as ammonia. 

This scheme is a hugely significant investment into the future of farming at Grosvenor, strengthening our commitment to operating in both a commercially sustainable and environmentally responsible way.

Mark Roach, Managing Director, Grosvenor Farms

The locations of our farms provide a unique opportunity to safely connect to the national high-pressure gas network, which runs adjacent to the facility, through underground pipes. Biomethane will be sent directly into the National Transmission System, which acts like a motorway for gas, moving it quickly and efficiently across the country.

CO₂ created during the biogas upgrading will be captured and liquefied for reuse in industry as Bio CO₂. The plant provides the potential to fuel Grosvenor Farm’s vehicles on its own biomethane, in due course. Specialist Netherlands’ firm HoSt Bioenergy Systems, a global leader in renewable energy, has been commissioned to build the facility.

As well as supporting employment during its construction, there will be four new long-term roles created, contributing to the local rural economy.

If you would like to join us at one of the UK’s leading dairy and arable farms, working by the principles of regenerative agriculture and circular farming, to produce renewable gas from agricultural waste – delivering a lasting commercial and social benefit in our local communities and beyond, we would love to hear from you.  

Grosvenor Farms employs more than 70 people in a wide range of specialist positions. Whether you are starting out as an apprentice, an experienced professional, or seasonal roles through the harvest, our people work in a valued, supportive and positively challenging environment where excellence is promoted and opportunities for further training and development are encouraged.
