What is Biogas?

What is biogas and it’s use in transport
Biogas is a renewable gas produced when organic materials such as food waste, slurry and crop residues break down through the process of anaerobic digestion.
Upgrading biogas by removing co2 and impurities creates biomethane, a high purity methane chemically similar to fossil natural gas but made solely from waste.
It can power heavy goods vehicles (HGVs) as compressed natural gas (CNG) or liquefied natural gas (LNG), offering fleets a practical, lower-carbon drop-in alternative to diesel. In the UK, the Renewable Transport Fuel Obligation (RTFO) incentivises the supply of renewable fuels, such as biomethane for road transport thereby accelerating their adoption across logistics and haulage.
How Biogas is Produced and Stored
From waste to wheel
Biogas is produced through anaerobic digestion and then upgraded to biomethane, which meets strict European standards for grid injection and vehicle fuel quality.
Storage & formats
- CNG is typically stored at 200–300 bar (most commonly 200 bar at 15°C in European NGV standards) and dispensed at forecourts for day-to-day HGV operations.
- LNG is methane cooled to -160 °C, reducing it’s volume up to 600 times. This extends the range for long haul operations.
Advantages of Using Biogas as a Vehicle Fuel
Independent UK trials show 84% well-to-wheel greenhouse gas savings for trucks running on 100% biomethane versus diesel. When biomethane is produced from waste (e.g., manure). The overall lifecycle impact becomes carbon negative when biomethane is produced from waste.
The UK’s RTFO recognises and rewards sustainable renewable fuels in transport, supporting the business case for fleets to transition now.
Environmental Benefits of Biogas over Diesel or Petrol
- Up to 84% WTW CO2e saving on dedicated biomethane which becomes carbon negative when derived from certain waste sources.
- Lower fuel lifecycle risk by converting unavoidable wastes into energy rather than flaring or venting methane.
