Evaluated field trial of bio-gas trucks using SRF Logger data, telematics data, refuel data and modelling. Compared transport performance and total cost against baseline diesel trucks.
Cost of fuelling gas trucks is approx. 30% lower per tonne.km of transport work, compared to diesel trucks.
When running on CNG, their equivalent carbon emissions are approximately 19 % lower than the baseline diesel, and when running on bio-gas, their equivalent carbon emissions are approximately 74 % lower.
Considering the total cost (capital cost and refuel cost), excluding the labour and maintenance costs, compared to a baseline diesel truck, the break-even period of a gas truck fuelled by bio-gas is approximately 2 years.
% fuel saving
30 % lower fuel cost
19 % lower CO2e for CNG (74 % lower for bio-gas)
Cost of implementation
A gas tractor costs approximately £30000 more than a diesel tractor. Payback period of approx. 2 years.
CNG is ready for implementation now. However, the amount of available bio-gas is not sufficient to convert all diesel tractor units in the UK with gas tractors fuelled with bio-gas.
