Owing to the urgent need for reducing energy-related CO2 emission, the demand for alternative fuels and gases, which help in reducing these emissions, is on the rise. Liquid hydrogen is one such source of energy. With the use of hydrogen, economies can significantly contribute to the decarbonization in the atmosphere. The process of decarbonization of energy is one of the major drivers of the market. At present, liquid hydrogen is in demand for its wide ranging applications, including high level of purity. It is commonly being used across end-use industries, including transportation, electronics, refining, chemicals, metals, glass, and others. Liquid hydrogen is also used in large volumes in the space industry as rocket fuel for combustion and as a propellent for space vehicles and nuclear-powered rockets. In addition, liquid hydrogen is used to avert oxidation and decrease the use of metal oxides during heat treatment of certain alloys and metals. It is used as a raw material ...
