In the midst of anthropogenic climate change, demand is high for hydrogen fuel because it doesn’t emit CO2; however, commercialisation of hydrogen has been restrained because it is difficult to transport. One new solution is liquid organic hydrogen carriers (LOHCs). As the name suggests, LOHCs are liquids that carry hydrogen! Unlike compressed or liquified hydrogen, LOHCs can leverage existing global infrastructure (pipelines, tankers and pumps) that already exists for petrol distribution. This thesis investigates the separation of used and fresh LOHCs, by creating specialised materials with molecular pores. It aims to improve LOHC efficiency for cheap and safe hydrogen distribution.
