Driven by a desire to produce a step change reduction in fleet carbon dioxide (CO2) emissions, Coca-Cola Enterprises (CCE) contracted Cenex to evaluate and compare the emissions, fuel consumption, economics, reliability and operability of a 26 tonne Iveco Stralis gas vehicle with that of a diesel Stralis vehicle.
Gas vehicle operation reduced NOx and PM emissions by 85.6% and 97.1% respectively. The gas vehicle achieved a 50.3 per cent saving in well-to-wheel GHG emissions, compared to the diesel Stralis vehicle. However, this was achieved using a temporary filling station – a more efficient permanent station being installed at the CCE depot raises the GHG saving to 60.7 per cent. Additionally, operating the gas vehicle on biomethane reduced the fuel costs by 12.8 per cent.
