The role of hydrogen in heavy transport to operate within planetary boundaries

Abstract

Green hydrogen -i.e., produced from renewable resources- is attracting attention as an alternative fuel for the future of heavy road transport and long-distance driving. However, the benefits linked to zero-pollution...

Environmental sustainability assessment of large-scale hydrogen production using prospective life cycle analysis

“…Such contextualization is important to determine how problematic certain outcomes for the planet are [34]. Examples in the literature include assessing the reduction of pressures on the PBs for switching from diesel to hydrogen in heavy road transport [35], determining the true cost of hydrogen production methods (i.e., cost of production plus environmental externalities) [30], and comparing the human health impacts of negative emission technologies to common diseases [36].…”

Environmental Sustainability Assessment of Hydrogen from Waste Polymers

“… 33 These limits can be derived from the planetary boundaries (PBs) framework, introduced by Rockström et al 34 and later updated by Steffen et al, 35 which represent ecological limits on nine Earth-system processes delimiting a safe operating space (SOS) for humanity. A recent study by Valente et al 36 employed the AESA method to showcase the potential of green H 2 in the heavy transport sector, which could help the latter operate within the SOS for humanity.…”

Absolute environmental sustainability assessment of renewable dimethyl ether fuelled heavy-duty trucks

“…47 Furthermore, Valente et al assessed hydrogen fuel cell trucks relative to the PBs. 48 For the rst time, here we investigate whether DME from fossil and renewable carbon is sustainable in absolute terms using seven PBs. We nd that, although renewable DME could reduce impacts substantially, most routes would still exceed at least one PB, which calls for optimised portfolios of renewable fuel technologies to decarbonise the HD road activities effectively.…”
