Prospective life cycle assessment can help identify solutions that can minimize environmental impacts of hydrogen production along transition scenarios. Guidance should consider existing and emerging technologies, possible temporal and regional differences, and broader socio-economic scenarios that determine the context of these developments.
Yet it is still unclear how the hydrogen economy will evolve and which environmental impacts it will cause. Prospective life cycle assessment can help identify solutions that can minimize environmental impacts of hydrogen production along transition scenarios.
So far, there are no assessments that investigate the sustainability of different technological options for forecasted hydrogen production levels in a global context, comparing impacts to geophysical limits, such as the Planetary Boundaries (PBs) proposed by Rockström et al. [ 33] or known impacts of human activity in the present.
Valente et al. (2021) investigated the environmental impacts of hydrogen production via wind-powered electrolysis, biomass gasification and natural gas-based SMR, and found large variations in the impact values according to the applied production pathways with biomass gasification having the least global warming impact.
Yet, the full range of environmental consequences of large-scale hydrogen production remains unclear. Here, prospective life cycle analysis is used to compare different options to produce 500 Mt/yr of hydrogen, including scenarios that consider likely changes to future supply chains.
They examined the environmental impacts of a nuclear-based hydrogen production via thermochemical water splitting using a copper chlorine cycle. The parametric studies demonstrate that the effect of plant lifetime on the environment per kg hydrogen production diminishes at large-scale production capacities.
