Hydrogen for Transport
The advantage of hydrogen liquefaction is that a cryogenic hydrogen tank is much lighter. Hydrogen's physical properties means hydrogen ... , liquid hydrogen turns into pure para hydrogen over the course of a few days. The process releases enough heat to turn the liquid hydrogen to gas in a few days. Liquid hydrogen can ...
