HOW HYDROGEN LIQUEFACTION WORKS
Hydrogen liquefaction is the process of cooling and condensing hydrogen gas to convert it into a liquid state. This is done by subjecting the hydrogen gas to extremely low temperatures, typically below -253°C (-423.67°F), which is its boiling point at standard pressure.
THE PROCESS TO CREATE HYDROGEN LIQUEFACTION
The liquefaction process involves compressing the hydrogen gas to increase its density, and then cooling it down to condense it into a liquid form. The cooling is usually achieved by a combination of cooling methods, such as by using a cryocooler or a heat exchanger to remove heat from the gas, and then using an expansion valve to lower its temperature further.
THE BENEFITS BEHIND HYDROGEN LIQUEFACTION
Liquefied hydrogen has a higher energy density than hydrogen gas, making it more practical to store and transport in certain applications. It is also used as a coolant in various industrial processes, such as in the production of semiconductors and in the superconductivity research.
