Green hydrogen is pivotal for transforming China's clean energy systems, yet analyses of various carriers and green electricity transmission remain limited. This study investigates cost dynamics supply across six pathways from production to refueling within China, encompassing such as liquid (LH2), organic carriers, methanol (CH3OH), ammonia (NH3). These are categorized into the pathway (I) (II), wherein delivered renewable-rich regions demand centers on-site production, considering potential risk associated with storage transportation large volume hydrogen. The results show that (II) yields lowest at 12.07 USD/kg. In contrast, CH3OH most expensive option 30.70 Operational expenditures primary drivers costs, while capital significantly influence conversion delivery phases, especially NH3 LH2. Transportation distance critically affects overall cost. Pathway remains economical over 500–5000 km. LH2 preferred beyond 700 km; surpasses LOHC 2150 km pipeline 4300 Furthermore, longer annual operating hours shorter distances can greatly reduce costs. For example, drops by 92% increase 1000 5000 decreases 500 Regional variations primarily attributed spatial distribution renewable resources. findings highlight importance developing region-specific strategies upgrading infrastructure enhance cost-efficiency chain.
