The entire industry chain of hydrogen energy includes key links such as production, storage, transportation, and application. Among them, the cost of the storage and transportation link exceeds 30%, making it a crucial factor for the efficient and extensive application of hydrogen energy [3].Therefore, the development of safe and economical
For instance, a research study was conducted to evaluate the cost of hydrogen production from wind energy [18] and found that while the cost of electricity ranges from 0.063 to 0.079 $/kWh, the cost of hydrogen is 2.118–2.261 $/kg. However, it did not consider the cost of hydrogen storage and transportation. The layout of the
In July 2021 China announced plans to install over 30 GW of energy storage by 2025 (excluding pumped-storage hydropower), a more than three-fold increase on its installed capacity as of 2022.
