John Lewis chooses Prins dual-fuel for low-carbon trucks 17 November 2014

John Lewis Partnership is now running the Prins Autogas Dieselblend 2.0 dual-fuel conversion on 38 new DAF CF distribution trucks as part of its programme to reduce CO2e emissions using bio-methane.

The deal to convert its diesel tractor units followed three months of trials and means that John Lewis' distribution fleet is now using CNG (compressed natural gas) blended with diesel and will soon be achieving up to 36% reduction in carbon emissions.

Prins Autogas UK received confirmation of the order after it met John Lewis' requirements, which included less than 8% efficiency slip for diesel engines using the CNG and diesel dual-fuel blend.

With the Prins dual-fuel conversion, John Lewis' DAF CFs are expected to have a range of 600—700 miles, and if the CNG runs out, the engine automatically switches back to 100% diesel for another 200 miles.

"We have big ambitions to reduce the carbon footprint of our fleet, and the use of low carbon fuels, especially bio-methane, is fundamental to this," comments Justin Laney from John Lewis.

"We see dual-fuel CNG as a good pathway to using greater quantities of bio-methane in our heavy truck feet," he continues.

"The Prins conversion met our performance criteria, and we now have 38 trucks running this system, delivering to both John Lewis and Waitrose branches," he adds.

"We are delighted to have been able to achieve the parameters and operating efficiencies JLP set us for its HGV fleet and to reduce its carbon footprint," comments Will Putter, commercial director at Prins Autogas UK.

"The Prins Autogas Dieselblend 2.0 system has been developed to be used in a variety of vehicles and engines as a practical way to achieve emissions reductions for an existing fleet."

Its dual-fuel system is suitable for all diesel engines and works by using a computer-controlled injection system to replace an optimum amount of diesel with gas (CNG or LPG). It communicates directly with the vehicle's ECU (via CANbus).
