ETI – PHEVs needed to help decarbonise HGV fleet

To bridge the gap to zero emissions vehicles, plug-in hybrid vehicles (PHEV) heavy goods vehicles while pure electric technology catches up according to the government-backed Energy Technologies Institute (ETI).

The ETI report, ‘HGVs and their role in a future energy system’, looks at decarbonising heavy road transport as part of the wider energy system in an attempt to achieve an 80% fall in greenhouse gas emissions and then the eventual target of net zero.

It shows that HGVs account for around 4% of total UK carbon emissions. If not properly addressed this could hit 15% by 2050. Electrification of the HGV fleet is the most promising long-term solution, but the fleet duty cycle and cost/packaging requirements pose challenges for existing technologies. Gas-electric plug-in hybrid vehicles could act as a bridging solution from 2025 to 2040 while fully zero CO2 tailpipe emissions options are developed.

ETI Chief executive Jonathan Wills 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.”
