Our Business Model

GFD is rethinking the way that anaerobic digestion is integrated into progressive farms. Unlike other developers, our business model is based on creating fully funded, complete end-to-end biogas projects with no requirement for capital investment by the farmer. Our fresh approach to long-term AD partnerships includes site identification, planning, development, funding and construction, as well as operation of the plant once commissioned.

It’s time to rethink AD. Here’s what makes us different…

Our innovative hub-and-spoke model allows plants to be built wherever feedstock – such as slurries, manures, agricultural waste or food waste – is plentiful, even if sites do not have a viable gas grid connection point. At the same time, we maximise the valuable outputs of the AD process including renewable energy (biomethane gas), heat, carbon dioxide and digestate biofertiliser, to support progressive farmers on their journey towards net zero.

6 steps to AD success

Site Qualification

Farmer or land agent who believes their site meets the criteria for a biogas project contacts GFD. We work with them to determine project feasibility, such as location, access to feedstock, etc.

Regulatory and Planning Management

We design the plant and manage the planning application process, including compliance with all necessary local and national regulations, to ensure approval first time.


Project funding is a key priority from day one – not an afterthought. We source full investment in partnership with our preferred funding partner: SWEN Capital Partners.

Feedstock and Energy Planning

We work with the host farmer (and neighbouring farmers if necessary) to secure reliable feedstock supply and ascertain local energy demand.

Construction and Commissioning

Working with our team of renowned technical suppliers and partners who specialise in on-farm AD, the plant is constructed and tested, before full commissioning takes place.

Operation and Maintenance

Using our experience in asset management, we can appoint an experienced O&M manager to run the plant, leaving the owner to get on with the job of running their farm. Energy and digestate is sold locally and biogas is either transported to one of our nearby hubs or upgraded and injected into the local gas grid as biomethane. Where viable, other products such as clean CO₂ are supplied to relevant markets, maximising revenue potential.

The GFD hub-and-spoke model

Our innovative hub and spoke model ensures that sites with limited or no viable gas grid connection point can still benefit from on-farm AD.

Hub = A central AD plant with good gas grid access.
Spokes = Smaller on-farm sites with abundant feedstock and no gas grid access.

Surplus biogas is upgraded to biomethane, compressed and transported from remote on-farm plants (the spokes) using low carbon, biomethane-fuelled tankers to the master AD plant (the hub), where it is injected into the gas grid.
