Cenex has developed a performance simulation tool for fleets looking to operate dual-fuel (gas/diesel) HGVs.

It will enable fleet operators to calculate the cost and carbon emission savings from dual-fuel trucks and compare with their diesel counterparts.

The new software will be incorporated into the existing Cenex Fleet Carbon Reduction Tool.

It follows a three-year R&D project, part-funded by Innovate UK, as part of the government’s Low Carbon Truck trials.

Steve Carroll, senior technical specialist at Cenex, said: “The real benefit is that we can assess gas vehicle performance before the onset of costly vehicle trials or purchases. The truck model allows us to show the cost and carbon benefits of operating gas trucks in a bespoke fleet environment.

“We record GPS data from fleet vehicles and run this through our model, which allows us to estimate the total cost and emission savings, not only for the fleet but also on a per route basis.”

Throughout the three-year R&D project, Cenex managed the performance evaluation of 40 natural gas trucks for a major UK distributor.

It led the testing and validation work that reported on truck performance during the trial including economics, fuel consumption, carbon emissions, noise performance, air quality performance and driver perceptions and attitudes towards gas vehicles and refuelling stations.

Chris Walsh, head of technical support at Cenex, said, ‘Working on the deployment and evaluation of the gas trucks has given Cenex valuable understanding of vehicle performance in real-world scenarios and allowed us to develop the tools necessary to support the economic roll-out of gas vehicles into heavy duty fleets.”
