Large-capacity high-pressure hydrogen tank

Solving the wall penetration problem of high-pressure hydrogen gas and hydrogen embrittlement.

At atmospheric pressure, the weight of 1000 liters of liquid hydrogen is 70.8 kg. The weight of 1000 liters of hydrogen gas at room temperature and atmospheric pressure is 0.0899 kg. At room temperature and atmospheric pressure, 1000 liters of hydrogen gas is compressed to 1.25 liters at 800 atmospheres. Therefore, the weight of hydrogen at room temperature and atmospheric pressure (1000 liters) and the weight of hydrogen at room temperature and 800 atmospheres (1.25 liters) are both 0.0899 kg. To compare with the weight of liquid hydrogen, it is necessary to convert the hydrogen gas at room temperature and 800 atmospheres to 1000 liters. 1.25 liters of high-pressure hydrogen gas at room temperature and 800 atmospheres becomes 1000 liters when multiplied by 800. Therefore, the weight of 1000 liters of high-pressure hydrogen gas at room temperature and 800 atmospheres is 800 times 0.0899 kg, which is 71.92 kg. The weight of liquid hydrogen (atmospheric pressure, -253 degrees) is 70.8 kg. Thus, the high-pressure hydrogen gas compressed at 800 atmospheres (71.92 kg/1000 liters) has a greater density than liquid hydrogen (70.8 kg/1000 liters). It can be seen that when transporting hydrogen in tanks of the same size, high-pressure gas can transport more hydrogen than liquid hydrogen.
