About 10 to 20 times. The storage and transportation cost of hydrogen energy is four times higher than that of gasoline, and the cost of hydrogen energy production is higher than that of gasoline and electricity. The safety of hydrogen energy storage and transportation is also a concern for the industry.
At present, it is mainly focused on technical research and has not yet formed related industrialization. It's just an experiment now, and we won't see the results until ten years later. Some people make money by shorting BYD, exaggerating facts, ambiguity, and confusing the public. Only electric vehicles will be developed first, and then hydrogen energy will be developed later.
It is understood that the working principle of hydrogen fuel cells is to combine hydrogen and oxygen to generate water, converting chemical energy into electrical energy and a small amount of heat energy. The heat generated by hydrogen energy per unit mass is three times that of gasoline. , the theoretical conversion efficiency is as high as over 90%.
At present, the application of hydrogen energy in the aerospace industry is very mature, and the fuel that propels rockets into space is liquid hydrogen. This also fully illustrates the characteristics of hydrogen energy such as high energy density and sufficient power.
The hydrogen energy supply chain has three links: production, storage and transportation, and filling. However, every link faces high cost issues, especially the filling link.
At present, the cost of a fixed hydrogen refueling station capable of filling 500 kilograms of hydrogen per day is between 7 million and 12 million, which is equivalent to three times that of a traditional gas station. Coupled with the high costs of equipment maintenance and labor, the price of terminal hydrogen will add an operating cost of 14 yuan/kg to the station price.
