Coca-Cola HGV Trial

By

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.

The trial vehicles – one operating solely on biomethane gas, and one diesel powered – were highly comparable. Both were new registrations at trial commencement and met Enhanced Environmentally friendly Vehicle emission standards.

Iveco

Temporary gas vehicle refuelling infrastructure was installed at the CCE depot in Enfield, UK where the trial vehicles were operated from.  Vehicle activity data from the Enfield depot was logged via onboard telemetry and a drive cycle (a speed versus time cycle) was produced.  The CCE drive cycle was a 30 minute 19.5 km cycle statistically representative of vehicle distribution patterns from Enfield. Testing vehicles over the CCE drive cycle in an emissions testing facility allowed air quality performance as well as tailpipe CO2 and fuel consumption to be measured in a controlled and repeatable environment.

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. On conclusion of the trial CCE invested in a fleet of 14 gas Iveco Stralis vehicles and a gas station which is due to be operational at the Enfield depot in June 2012.   The new CCE gas fleet will consume approximately 168 tonnes of biomethane saving  over 300 tonnes of CO2, 1590 kgs of NOX and 33 kgs of PM emissions per annum.
