Natural Gas/Biomethane

CNG vehicles run on Compressed Natural Gas, the same gas we use to power our central heating boilers and cookers. CNG is stored on the vehicle in pressurised cylinders and used in a spark ignition engine, which is the type of engine used on petrol vehicles. CNG is a fossil fuel; however a renewable and sustainable version is also available, known as biomethane. Biomethane is produced from organic waste and can be directly used in CNG vehicles.

Fit for purpose

  • CNG vans can undertake similar duties to regular diesel vans due to the long range available between refuelling.
  • Payload is often reduced by about 10% due to the weight of the gas tanks. Load space is not affected.
  • A limited but growing number of public CNG refuelling stations are available across the UK which are capable of filling the fuel tank in a few minutes. Smaller home or depot based refuelling units can compress natural gas from the gas network directly into a vehicle’s tank overnight.
  • CNG vehicles can have a reserve petrol tank in case you run low on gas away from a refuelling station.

Operational performance

  • Up to 300 miles on a full tank, plus petrol reserve.
  • Ideal operation: city, suburbs, motorway. Back to base. High mileage.

Environmental performance

CNG vehicles are good for air quality; they are quiet and emit similar levels of CO2 to diesel vans. If operated on biomethane, fuel life cycle CO2 savings of over 60% are available.

Compared to diesel:

  • Tailpipe CO2 – similar
  • Fuel life Cycle CO2 – similar for CNG, over 60% if using biomethane
  • Good for air quality
  • Low noise.
