dc.description.abstractTransporting hydrogen in liquid state holds promise as a cost-effective solution for long-distance and large-scale distribution. This paper investigates the feasibility of the application of a membrane-free water electrolyser for liquid hydrogen production. Both conventional alkaline and membrane-free water electrolysers are considered for hydrogen production. The hydrogen produced by these electrolysers are used as the feedstock for subsequent purification and liquefaction processes. Aspen HYSYS is used for systematic investigation of the impact of electrolyser operating conditions and hydrogen purity on the total power consumption for liquid hydrogen production. The findings reveal that, if the safety concerns of the membrane-free water electrolysers can be addressed, they can offer an energy-efficient alternative to alkaline water electrolysers, potentially reducing power consumption by approximately 4 %–10 %.
