AND ALTERNATIVE FUELS
particulate pollution that " zero emission " vehicles still
cause. It is therefore vital that energy efficiency is
improved. Active travel is the key to green economic
growth, clean cities, and unlocking the energy saving
potential of public transport.
Unsettled issues regarding power options for
decarbonized commercial vehicles
(EPR2021021)
While direct electrification appears to provide the most
cost-effective route to decarbonization of commercial
vehicles, uptake may be constrained by critical metal
supply. Additionally, it will be many years before hydrogen
power becomes decarbonized or if it can ever compete
economically with direct electrification. An electric road
system (ERS) could offer a highly efficient and costeffective
route to direct electrification that would greatly
reduce the volume of batteries required, but pilot schemes
are urgently needed to provide concrete data on operating
costs for different ERS technologies.
Furthermore, if plug-in hybrid electric vehicles could
obtain most of their power from an ERS, liquid biofuels
and " electrofuels " may prove useful for occasional offgrid
range extension. To achieve extremely long-range
for operation in remote locations, liquid fuels remain the
only viable option. n
decarbonization objectives and ignores the significant
particulate pollution that " zero emission " vehicles still
cause. It is therefore vital that energy efficiency is
improved, and that a wider matrix of energy sources
becomes available so that users and industry alike
take advantage of the best option for each specific
application. n
