LPG solution for carbon cutting

Published:  21 March, 2011

UK: Lafarge is looking to further cut its carbon footprint with the introduction of new LPG dual fuel systems for its tipper truck fleet.

The new initiative follows the company’s investment in nine new lighter vehicles which offer improved load potential, to reduce delivery movements and carbon output.

The initiative, undertaken in partnership with LPG fuel specialists Flogas and dual fuel systems firm G-volution, is expected to bring additional carbon savings and further strengthen the firm’s commitment to sustainability.

John Dargie, dead of distribution and transport for Lafarge Aggregates & Concrete UK, said: “We estimate the dual fuel system will offer an immediate saving of 10% on carbon emissions as well as a similar level of reduction in fuel costs thanks to the introduction of an LPG tank.

“Clearly this makes sense from an economic and environmental perspective. Going forward over the next 10 to 20 years we will all need to look at alternative ways to fuel our fleet so this is a good start.”

Initially, one truck is being fitted with the dual system G-volution the experts in developing and installing Multi-fuel control technology, with a view to more vehicles being converted if the trial is successful.

The dual system features an optimiser which delivers a precise fuel mix of more than one fuel at the point of combustion while maintaining the OEM power and torque ratings.

Simon Pickess, commercial sales director at G-volution, explained: “As the fuels are combusted simultaneously, rather than one at a time, the optimiser continually adjusts the relative ratios of the two fuels when operating in dual-fuel mode. This ensures optimal operation at all times with net fuel cost and carbon output savings virtually unaffected by changes in operational conditions, load or driver behaviour. The driver himself experiences no change in the vehicle’s operation apart from having to fill up with two fuels rather than one.”

In addition to a regular diesel tank, the vehicle will also feature an LPG tank, which will enable the company to benefit from the low carbon properties of the fuel.
