Hydrogen energy is a green energy source and is being increasingly appreciated. Hydrogen is the lightest atom known, and its density is extremely low at room temperature and normal atmospheric pressure, and it needs to be stored with its density increased for application to vehicles. There are two methods to increase density: 1. compression: it is now common practice to compress the hydrogen to 35 mpa or 70 mpa. This requires a high strength storage tank and therefore the weight of the tank far exceeds that of hydrogen, in the 1 ton hydrogen 10 ton tank. In addition, 35/70 MPa is a very high pressure gas, which is very dangerous to store or transport. 2. Liquefaction: the hydrogen gas is cooled to-252.67 ℃ to obtain liquefied hydrogen gas, and the density of the liquefied hydrogen gas is 845 times of that of the liquefied hydrogen gas at the normal temperature. The disadvantage is that the liquid hydrogen will vaporize due to the influence of the ambient temperature, limiting the storage time and transport distance of the liquefied hydrogen. The second method is generally adopted in the existing hydrogen storage and transportation, but liquid hydrogen is affected by the ambient temperature in the transportation process, the liquid hydrogen can be evaporated and vaporized, the internal pressure of the storage and transportation device is increased, danger is easy to occur, and long-time storage and transportation cannot be realized, so that improvement is urgently needed.
