What will be Australia’s biggest electrolyser – a platinum-using proton exchange membrane or PEM electrolyser – is on order to provide green hydrogen Down Under at a time when the planet’s lightest molecule is being highlighted as the ‘slam dunk’ of heavy-haul transport in a decarbonising world. Viva Energy Australia has ordered the PEM water electrolyser from Nel Hydrogen US. When installed, it will provide green hydrogen to a fleet of heavy-duty fuel cell electric vehicles (FCEVs), which also use platinum group metals (PGMs) to catalyse the conversion of hydrogen into electricity for vehicle mobility and, if needed, also stationary power.
