| Abstract: | In this study, the environmental aspects of H2 pathways are analyzed according to plausible H2 production methods, production capacity, and distribution options in Korea, using life cycle assessment (LCA) methodology. The target H2 pathways analyzed are H2 via naphtha steam reforming (Naphtha SR), H2 via natural gas steam reforming (NG SR), H2 via liquefied petroleum gas steam reforming (LPG SR), H2 via water electrolysis with wind power (WE[Wind]), and H2 via water electrolysis with Korea electricity mix (WE[KEM]). The results are then compared with those of conventional fuels (gasoline, diesel, and LPG) to identify which H2 pathway has less environmental impact than the conventional fuels. |
