London Borough of Hackney
Refuse Collection Vehicle Engine Testing at Millbrook Proving Ground. Comparison of Emissions with Three Fuels:
Diesel, Hydrotreated Vegetable Oils and GREEND+
At just over 470 vehicles, London Borough of Hackney (LBH) operates one of the largest local authority fleets in London. LBH aims for all of its commercial vehicles to be ultra low emission vehicles (ULEVs) by 2028. Ideally this will be achieved by using electric vehicles which have zero tailpipe emissions. However, current vehicle technology does not currently support this vision, particularly for the heavier vehicles, so LBH is using renewable fuels to minimise its emissions.
LBH trialled and deployed GREEND+ HVO supplied by GBF across its commercial vehicle fleet of Refuse Collection Vehicles. Analysis undertaken by LBH has found that this fuel offers well-to-wheel CO2 emissions savings of 80% compared to conventional diesel. The fuel has performed well from an operational point of view. HVO requires no additional maintenance or changes to operational procedure as it is used as a direct replacement for conventional diesel so there is no additional capital expenditure. It represents a cost-effective option for reducing fleet carbon emissions and improving local air quality.
The improvements in Local Air Quality through using GREEND+ were very significant with reductions in NOx of 29% and Total Particulate matter of 85% over standard diesel on a EuroVI Refuse Collection Vehicle.
