The engine behind its impact runs on 100 percent renewable biomethane, produced from genuine waste, including food scraps, animal slurry, sewage and grass clippings, through anaerobic digestion. Chemically identical to fossil methane, the fuel can be injected into the UK’s existing gas grid and distributed through established infrastructure. When used in natural gas vehicles, it requires no engine modification or driver retraining, offering a drop-in, low-carbon alternative that’s easy to adopt—available today.
Vehicles running on CNG Fuels’ biomethane cut emissions by more than 85 percent and reduce fuel costs by up to 30 percent. They deliver the same reliability and performance as diesel, without the trade-offs of other low-carbon options, such as long queues, complex refuelling or retraining needs. Refuelling takes just 8 to 10 minutes and supports ranges of up to 500 miles. Stations are open 24/7, unmanned and equipped with up to 14 high-throughput dispensers tailored to real-world logistics demands.
“This is a business where uptime equals credibility,” says Baden Gowrie-Smith, CFO. “We built our name on never letting a truck turn away.”
With over 2,000 trucks refuelling daily at 16 live stations, and three more opening soon, CNG Fuels has laid the foundation for mass-market adoption. Its current capacity exceeds 10,000 trucks per day, and with more than 120 stations in development, the company is scaling rapidly to meet growing demand. Backed by institutional investor Foresight Group, it plans to launch at least three new stations annually, strategically positioned along key logistics corridors.
Low-Carbon Freight That Pays Off
Biomethane’s operational simplicity is matched by its financial clarity. With a typical five-year vehicle lifecycle, many fleets are now onboarding 40 to 50 trucks at a time, finding that switching to biomethane offers a strong return on investment while insulating them from volatile diesel markets and tightening emissions targets.
Unlike crop-based fuels that depend on limited agricultural feedstocks and face cost pressure from cross-sector demand, biomethane stands out for its scalable production, diverse waste inputs and full compatibility with existing infrastructure. As demand intensifies across sectors like aviation, this supply resilience positions biomethane as one of the most dependable and future-proof low-carbon solutions available.
Adoption is accelerating. Once limited to 4x2 trucks, biomethane is now powering a growing number of factory-built 6x2 models from leading OEMs such as Scania and Iveco, opening the door to broader fleet participation. Already fuelling 10 percent of the UK’s 4x2 HGVs, CNG Fuels is well positioned to replicate that reach across the 6x2 segment.
Early partnerships helped validate the model. The John Lewis Partnership, the parent company of Waitrose and John Lewis, began by trialling retrofitted dual-fuel trucks. Their successful experience with these led them to commit to a fleet of dedicated biomethane trucks which in turn helped accelerate CNG Fuels’ infrastructure rollout and paved the way for adoption by nearly every major UK supermarket and parcel delivery provider.
Clean freight doesn’t have to wait. CNG Fuels has built the infrastructure, secured the fuel supply and proven the model. In a sector where change is complex and risk-averse, it offers a rare solution that is commercially viable, low in carbon emissions and easily integrated into existing logistics networks. It is ready to scale today.
