Emissions Analytics has just completed its part in the three-year project, entitled ENTRIS (Evaluation of Natural Gas Trucks and Refuelling in Swindon) which was part-funded funded by Innovate UK.

The trial involved a total of 55 heavy duty vehicles retrofitted with dual fuel diesel/compressed natural gas systems. The trial vehicles covered over 11,374 miles in a total of 34 tests over 246 hours, and generated more 2.5 million data points.

In total, said Emissions Analystics, the trial showed a six per cent average reduction in fuel operating costs although this was sensitive to the changing relative price of diesel and gas.

The analysis of the data collected also found that on average there was a nine per cent reduction in CO2, along with 16 per cent reduction in NOx emissions and lower NO2. Methane slip was also identified and the government is funding further investigations into this issue.

ENTRIS was one of several projects under the Low Carbon Truck Demonstration Trial.

Starting in January 2013 and finishing in March 2016, the projects’ consortium members include three truck operators: Howard Tenens, John Lewis Partnership and Lenham Storage. In addition, telematics specialist CMS SupaTrak provided the link between Emissions Analytics’ data and the tracking of vehicles as they travelled the country.
