Its applications [ Return towards  Hydrogen  ]

Hydrogen’s mainly used is to eliminate the sulfur that is naturally contained in oil, in order to produce clean fuels: this is desulfurization. The hydrogen supplied by Air Liquide supplies to refineries all over the world makes it possible to avoid the release of about 780,000 tons of sulfur oxide a year into the atmosphere, or more than the quantity emitted each year by a country like France (450,000 tons).

Hydrogen is also used to fuel rockets and space launchers like ARIANE V.

It is also used: 

• In chemicals to make textile fibers like nylon, polyurethane foam and plastic material; 
• In the glass industry, to make flat glass; 
• In electronics, as a carrier gas; 
• In metallurgy, for the thermal treatment of steel.
