As part of the Low Emission Freight and Logistics Trial (LEFT), the Dedicated to Gas project evaluates the viability of Euro VI gas heavy goods vehicles (HGVs) as an alternative to diesel.
The project deployed 20 Euro VI vehicles running on biomethane, in a combination of compressed natural gas (CNG) and liquified natural gas (LNG).
Cenex analysed fuel economy, range, greenhouse gas (GHG) emissions, vehicle reliability, driver perceptions and emission testing results.
The trial vehicles travelled over 2.2 million kilometres saving over 1,400 tonnes of WTW CO2e; the same distance as 56 times around the globe and equivalent to the CO2 saved in the lifetime of 3,150 trees, which would occupy a forest equivalent to the area of 18 football pitches.
The project results show that, when compared to diesel, vehicles would make at least 17% GHG emission savings with a 25% biomethane blend (B25), and 100% biomethane (B100) yields savings of at least 76%.
The trial drivers from the project fleets reported that gas vehicles perform better than diesel comparators in engine noise, vibration, overall drive comfort, engine braking and environmental performance.
