This report compares the transport of hydrogen by pipeline as compressed gaseous hydrogen with three shipping pathways: ammonia, liquid hydrogen and liquid organic hydrogen carriers (LOHC). The focus is on hydrogen transport rather than the transport of commodities made using hydrogen (e.g. iron), noting that ammonia can be both a hydrogen carrier and directly used as a feedstock or fuel for different applications. Carbon-containing carriers (such as methanol or methane) are excluded since they would need a sustainable carbon source (biogenic or directly from air) to be considered renewable, and the cost advantages are not sufficient to compensate for this downside. The scope covers transformation from gaseous hydrogen to a suitable form to allow its transport and storage, its use in the transport step itself, and its reconversion from the carrier back to pure hydrogen (if needed). There are two main parameters that define the transport cost: the size of the production
