Abstract
To better align the fluctuating offshore wind power with stable hydrogen demand, this study develops a demand-driven hydrogen supply chain optimization model incorporating hydrogen production strategies. Under a cost-minimization objective, the model evaluates and compares the cost and carbon emissions of different supply chain configurations. Two production strategies are proposed: partial grid-connected and fully off-grid electrolysis, applied to a case study in Guangdong, China. Results indicate that the average supply chain cost for electrolytic hydrogen ranges from USD 6.6–8.2/kg. Due to spatial distribution and operational characteristics, the off-grid mode shows greater station concentration, leading to about USD 1.4/kg higher transportation costs compared to the grid-connected mode. In the short term, partial grid-connected electrolysis serves as a feasible transition pathway. In the long term, with declining electricity prices and carbon trading, the overall cost of off-grid electrolysis could decrease by 12 %–21 %, offering greater cost reduction potential.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
