Cost & Carbon Reduction

The G-volution Optimiser dual-fuel technology will deliver significant economic and environmental benefits to the Vehicle Operator.

In simple terms the G-volution Optimiser replaces a proportion of  the expensive and carbon-intensive primary fuel (diesel) with a less expensive and lower carbon-content secondary fuel, for example Natural Gas (CNG or LNG) or LPG

In road transportation the benefits already proven by major UK Fleets are:






  • Immediate 10-20 % reduction in Fuel costs depending upon choice of secondary fuel

  • 8-15 % reduction in CO2 (depending on the choice of secondary fuel and up to 50% reduction with biomethane)

  • No reduction in vehicle range when compared to diesel-only vehicle

  • Installation does not affect integrity of base vehicle, the vehicle can be configured back to original diesel-only specification at end of period or contract if required

  • Vehicles reverts back to 100% diesel-only operation if secondary fuel is unavailable
