Abstract
Abstract The production of green hydrogen from renewable energy produced from wind and solar resources is deemed a more promising solution due to high energy quality, comparatively easy storage compared to electricity, and the prospect of using it at the time of use. Hydrogen has increasingly emerged as a potential energy carrier, making a global hydrogen mobility infrastructure essential to accelerating the transition to a hydrogen economy. Therefore, this work presents a cradle-to-gate life cycle assessment (LCA) for four hydrogen delivery pathways: compressed gas via tube trailers (CGH 2 -TT), liquid hydrogen (LH 2 ), liquid organic hydrogen carrier (LOHC), liquid ammonia (LNH 3 ). The LCA results depict that for short distance of 100 km CGH 2 -TT is the most eco-friendly option with the lowest global warming potential (GWP) of 1.81 kgCO 2 -eq/kgH2. Whereas, the LOHC pathway has shown the worst results with the highest GWP of 3.58 kgCO 2 -eq/kgH 2 . Likely, delivery via LNH3 also showed significant emissions of 3.14 kgCO 2 -eq/kgH 2 and remained the second worst candidate or hydrogen delivery.
