Costs of Storing and Transporting Hydrogen
The cost of hydrogen storage and hydrogen transportation
Hydrogen energy is also a clean energy source today. However, it is widely used, and the cost of hydrogen storage and hydrogen transportation is a major problem.
The methods of hydrogen storage include high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, solid hydrogen storage, etc. High-pressure gaseous hydrogen storage has simple equipment and slightly lower cost, but its hydrogen storage density is small and transportation efficiency is poor. To store enough hydrogen, high-pressure containers are required, which increases equipment costs and also raises safety concerns. Low-temperature liquid hydrogen storage has high hydrogen storage density, but the liquefaction process can consume a lot of energy, resulting in a significant increase in costs. Liquid hydrogen storage requires low-temperature thermal insulation equipment to maintain its liquid state. The construction and maintenance of this equipment requires financial resources. Solid hydrogen storage is safe and the hydrogen storage density is expected to be high. However, the technology is not mature, the material cost is high, and it is difficult to use it on a large scale.
As for hydrogen transportation, pipeline hydrogen transportation and vehicle transportation are common methods. Pipeline hydrogen transportation has high efficiency and low cost. However, the construction of a hydrogen pipeline network requires a huge investment. The pipeline material needs to be specially selected to prevent hydrogen embrittlement and other problems, which increases the construction cost. And the regulation of the pipeline network can not be completed in a short time, and it requires long-term planning and investment. Vehicle transportation is flexible and convenient, but the transportation volume is limited. High-pressure gaseous hydrogen vehicle, the cost is relatively low, but it is limited by the density of hydrogen storage; liquid hydrogen vehicle, although the volume can be increased, the cost of liquefaction and heat preservation is high.
Overall, in order to reduce the cost of hydrogen storage and hydrogen transmission, technological innovation is required. Develop efficient and low-cost hydrogen storage materials, optimize hydrogen storage equipment, in order to increase hydrogen storage density and reduce energy consumption. For hydrogen transmission, it is necessary to build a scientific regulatory network to improve the efficiency of vehicle transportation. In this way, the cost of hydrogen energy can be moderate, and it can be widely used to help the clean transformation of energy.
