Hydrogen Fuel Cost Per Kg
On the cost per kilogram of hydrogen fuel
In today's world, the weight of energy is related to the livelihood of the people and depends on the rise and fall of the country. Hydrogen fuel has attracted much attention because of its cleanliness and efficiency, but its cost per kilogram is the key to restricting the popularization.
The way to produce hydrogen fuel is different. First, electrolysis of water to produce hydrogen, which relies on electricity to split water to obtain hydrogen. However, its cost is closely related to the price of electricity. If you take thermal power, although it is convenient, coal procurement and equipment operation and maintenance are expensive in the cost of thermal power, and the risk of carbon emissions from thermal power is contrary to the original intention of hydrogen fuel cleaning. If renewable energy is used to generate electricity by electrolysis of water, although it is low-carbon and environmentally friendly, the initial investment in wind energy and solar power generation equipment is huge, and it is restricted by natural conditions. The power generation stability is not good, and the cost per kilogram of hydrogen fuel remains high.
Second, the reforming of fossil fuels to produce hydrogen uses natural gas, coal, etc. as raw materials. Natural gas reforming technology is relatively mature, but the price of natural gas fluctuates, which has a great impact on the cost of hydrogen fuel. Although coal gasification hydrogen production is rich in raw materials, its process is complicated, and the purification process also requires a lot of resources. Moreover, coal is a high-carbon energy source, and the carbon emission of the hydrogen production process also needs to be considered. The superposition of various factors makes it difficult to reduce the cost of hydrogen fuel per kilogram.
Hydrogen fuel storage and transportation is also Hydrogen has special characteristics, low density, easy leakage, and storage requires high pressure or low temperature conditions. High-pressure hydrogen storage requires extremely high requirements for the material and manufacturing process of hydrogen storage vessels, and the container cost is high; low-temperature liquid hydrogen storage requires a lot of energy to maintain low temperature, and the evaporation loss during storage cannot be ignored. In terms of transportation, if pipeline transportation is used, the construction of pipelines requires a large investment, and special anti-corrosion, sealing and other technologies are required; if it is transported by vehicle, it is limited by the transportation volume and transportation distance, and the unit transportation cost cannot be underestimated.
Furthermore, the construction of hydrogen fuel filling facilities is also a major cost. The construction of hydrogen refueling stations covers land purchase, equipment installation, safety and many other aspects. Its equipment such as compressors, hydrogen storage tanks, filling machines, etc., rely on imports and are expensive. And in the early stage of operation of hydrogen refueling stations, due to limited demand for vehicle hydrogen refueling and low equipment utilization, the cost of hydrogen fuel per kilogram is further pushed up.
To reduce the cost per kilogram of hydrogen fuel, multiple efforts are required. In the production process, accelerate the technological innovation of renewable energy, improve power generation efficiency, reduce costs, and optimize the hydrogen production process of electrolytic water; or explore new hydrogen production paths to reduce dependence on traditional energy. In terms of storage and transportation, develop high-performance, low-cost hydrogen storage materials and transportation methods to improve safety and economy. In the construction of refueling facilities, increase policy support, encourage local enterprises to develop and manufacture related equipment, and promote the large-scale construction of hydrogen refueling stations to dilute costs.
Only by taking multiple measures and promoting coordinated progress can we effectively reduce the cost per kilogram of hydrogen fuel, make it shine on the energy stage, and inject strong impetus into the world's sustainable development.
