The Energy Technologies Institute (ETI) has suggested that hybrid vehicles may be necessary to bridge the gap to zero emission Heavy Goods Vehicles (HGVs).
Published on 29 August, HGVs and their Role in a Future Energy System noted that, while HGVs account for 4% of total UK carbon emissions, this could rise to a 15% share under certain scenarios by 2050. Electrification of the HGV fleet was determined as being the most promising long-term solution but owed to the fleet duty cycle and both cost and packaging requirements, this will pose challenges for existing technologies.
The report explained that gas-electric plug-in hybrid vehicles could serve as a bridging solution from 2025 to 2040, allowing time for zero CO2 tailpipe emissions options to be fully developed.
Jonathan Wills, Chief Executive Officer of the ETI, said: “The HGV sector is a difficult area to decarbonise and the share of UK carbon emissions from HGVs is set to rise by 2050 if no action is taken. Through this research we have identified plug-in hybrid HGVs as a viable next step if overall energy system transition costs are to be minimised. Changing the purchasing behaviour of fleet operators will also be really important to help investment in new technologies.”
