Abstract
Hydrogen produced from renewables works as an energy carrier and as
energy storage medium and thus hydrogen can help to overcome the
intermittency of typical renewable energy sources. However, there is no
comprehensive environmental performance study of hydrogen production and
consumption. In this study, detailed cradle to grave life cycle
analyses are performed in an isolated territory. The hydrogen is
produced on-site by Polymer Electrolyte Membrane (PEM) water
electrolysis based on electricity from wind turbines that would
otherwise have been curtailed and subsequently transported with gas
cylinder by road and ferry. The hydrogen is used to provide electricity
and heat through fuel cell stacks as well as hydrogen fuel for fuel cell
vehicles. In order to evaluate the environmental impacts related to the
hydrogen production and utilisation, this work conducts an
investigation of the entire life cycle of the described hydrogen
production, transportation, and utilisation. All the processes related
to the equipment manufacture, operation, maintenance, and disposal are
considered in this study.
