Liquid Hydrogen

Liquid hydrogen is the lightest fluid (at temperature of -250 °C, one litre of liquid hydrogen weighs only 67 grams) and solid hydrogen is the lightest solid (density 0.076 g/cm3). Hydrogen atoms are the smallest of all atoms. It is a colourless, odourless liquid, which gains explosive components with an ignition coefficient of 4-75% when mixed with air.

Liquid hydrogen is widely used in the industry as gas storage and in the aerospace industry as rocket fuel for internal combustion engines. The advantage of using hydrogen as fuel is obvious – its combustion product is water! Since the 1980s, Messer Group has in active cooperation with BMW been developing and improving the use of hydrogen in the automotive industry. Hydrogen is used for annealing high alloy steels and sintered parts as well as for oxide reduction in molten metal. It is used as an efficient fuel in glass polishing.
