Abstract:
In the future, centralized hydrogen production methods have greater potential for scale compared to on-site hydrogen production and utilization. The traditional hydrogen transportation methods are difficult to meet the requirements of safety and efficiency. There is an urgent need to develop hydrogen transportation technologies such as hydrogen compression, liquefaction, and new hydrogen-carrying materials to solve the technical problems in hydrogen transportation. Using the Hydrogen Delivery Scenario Analysis Model (HDSAM), taking Ordos, the green hydrogen city in Northern Xinjiang, as an example, the total storage and transportation costs of four hydrogen transportation modes including the tube trailer, liquid hydrogen tank truck, pipeline and a combination of pipeline and tube trailer under different hydrogen transportation scales were calculated and predicted. The key factors influencing the total storage and transportation cost of hydrogen was analyzed, the specific costs under different transportation modes and distances was refined, and low-cost hydrogen storage and transportation plans in the near future (2023—2030) was explored, in order to put forward feasible suggestions.The results show that regardless of whether the hydrogen refueling cost is included in the total storage and transportation cost, the transportation cost of the trailer (33.43-34.77 yuan/kg) is the lowest when the hydrogen transportation scales are
8000 tons and
42000 tons per year. If the refueling cost is not included in the total storage and transportation cost, the storage and transportation cost of liquid hydrogen tank trucks (37.32-46.16 yuan/kg) within the distance of 200-400 km is the lowest under the hydrogen transportation scales of
8000 tons,
42000 tons and
118000 tons per year. The combined transportation mode of tube trailer and pipeline has the lowest total storage and transportation cost (32.29-35.18 yuan/kg) under the scale of hydrogen transportation of
118000 tons per year and the transportation distance of 100-400 km. If the cost of hydrogen refueling is not included, the cost of liquid hydrogen tankers is the lowest within 400 kilometers. The pipeline transportation mode is not comparable to the economy of the other three modes within the scale of
118000 tons of hydrogen transportation per year. When the annual hydrogen transportation scale exceeds
416000 tons, the total storage and transportation cost of pure pipelines over a long transportation distance of
1000 kilometers will be lower than that of tube trailers and slightly higher than that of liquid hydrogen tankers.
