    规模化氢运输方式的技术经济性比较

    Comparison on tech-economic analysis of large-scale hydrogen transportation modes

    • 摘要: 未来集中式制氢方式相较于就地制氢用氢的方式,更具规模潜力。传统的氢气运输方式难以满足安全高效的要求,亟需研发氢气压缩、液化、以及新型载氢材料等氢运输技术,以解决氢气运输中的技术难题。本文利用氢气运输场景分析模型(Hydrogen Delivery Scenario Analysis Model,HDSAM),以北疆绿氢城鄂尔多斯为例,对不同运氢规模下管束拖车、液氢罐车、纯管道及管道和管束拖车相结合的四种运输方式的总储运成本进行计算,分析影响氢气总储运成本的关键因素,细化不同运输方式和距离下的具体成本,探究近期(2023—2030年)的低成本氢气储运方案,并提出可行性建议。结果表明不论是否将加氢成本包含于总储运成本当中,每年0.8万t和4.2万t的运氢规模下,100 km距离之内管束拖车的运输成本最低,约为33.43~34.77 元/kg;若不将加氢成本包含在总储运成本中,每年0.8万、4.2万t以及11.8万t的运氢规模下,液氢罐车在200~400 km距离之内储运成本(37.32~46.16 元/kg)都是最低。管束拖车和管道相结合的运输方式在每年11.8万t的运氢规模和100~400 km的运输距离下,总储运成本(32.29~35.18 元/kg)最低,若不计入加氢成本,则液氢罐车在400 km以内成本最低。纯管道运输方式在每年11.8万t运氢规模内,和其它3种方式的经济性,尚不具有可比性。当每年运氢规模超过41.6万t时,纯管道在1 000 km的长运输距离下,总储运成本会低于管束拖车,稍稍高于液氢罐车。

       

      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.
