Evaluation of Natural Gas Trucks and Refuelling in Swindon (ENTRIS)

A new natural gas refuelling station in Swindon will power 34 dual-fuel heavy goods vehicles while onboard sensors track their real-world emissions and fuel efficiency. This matters because heavy goods vehicles are a major source of carbon emissions and air pollution in the UK, yet most emissions data comes from laboratory tests rather than actual roads. The project fills a gap in understanding how natural gas performs as a diesel substitute under real driving conditions—including stop-start traffic, motorway speeds, and varying loads. If successful, the research will provide hard data on how much diesel natural gas can replace, and what the actual exhaust emissions look like. This could help fleet operators, local authorities, and logistics companies decide whether to invest in gas-powered trucks and refuelling infrastructure. The Swindon station will be open to third parties, meaning other operators can test the technology without building their own facilities. The findings could quietly reshape supply chains and urban air quality by giving decision-makers reliable, real-world evidence rather than manufacturer claims or lab estimates.
