Hydrogen is a colorless, odorless, flammable gas and the lightest known gas. Hydrogen is generally non-corrosive, but at high pressures and temperatures, hydrogen can cause embrittlement in some steel grades. Hydrogen is non-toxic, but not life-sustaining, it is a suffocating agent.
High purity hydrogen finds widespread usage in the electronics industry as a reducing agent and as a carrier gas.
Hydrogen is most frequently produced for on-site usage by steam reforming of natural gas. Such plants may also be used as sources of hydrogen for the merchant market. Other sources are electrolysis plants, where the hydrogen is a by-product of chlorine production, and various waste gas recovery plants, such as at oil refineries or steel plants (coke oven gas). Hydrogen is also produced by electrolysis of water.
Ultrapure hydrogen is mainly used in the manufacture of large-scale and very large-scale integrated circuits to provide a reducing atmosphere. High-purity hydrogen is used as the base gas for the preparation of mixed doping gases such as SiH4/H2, PH3/H2, B2H6/H2, etc.
Hydrogen finds some usage in the welding and cutting of metals.
Hydrogen is used in large quantities, (bulk supply or on- site generation) for the hydrogenation of vegetable and animal oils to produce margarine and other fats. Extremely pure hydrogen is used in the chemical industry for fine reduction processes.
Hydrogen in large quantities is used in petrochemical processes that include hydrodealkylation, hydrodesulphurization, hydrotreatment.
Hydrogen is used extensively in the metals industries because of its ability to reduce metal oxides and prevent oxidation of metals during heat treatment. It may be used ether pure, as is often the case when heat treating stain- less steel, or in a mixture with inert gases, argon or nitro- gen. It is used in the production of carbon steels, special metals and semiconductors.
Hydrogen is used as fuel in fuel cell applications. In electrical power plants hydrogen is used as a coolant gas in turbogenerators.
Liquefied hydrogen is used as a rocket fuel. In the laboratory liquid hydrogen is employed for solid physics research.
In the nuclear industry para-hydrogen is employed to fill bubble chambers.

The molar mass of hydrogen is 2 g/mol.
The most common use of hydrogen is to fill hydrogen balloons and hydrogen airships; when hydrogen reacts with oxygen, it releases a lot of heat, which can be used for welding or cutting metals and high-energy fuels; hydrogen is also an important chemical raw material.
Half of the hydrogen comes from natural gas, coal mines and other natural sources. The method of electrolysis of water can produce hydrogen, but it consumes a lot of electricity. High temperature and high pressure of carbon and water also generate carbon monoxide and hydrogen.
An important use of hydrogen is in the hydrogenation of fats in margarines, cooking oils, shampoos, lubricants, household cleaners, and other products.
The electronics industry can use hydrogen to produce high-purity silicon, a semiconductor material. Utilizing the property that hydrogen can extract oxygen from oxygen compounds, metals can be smelted in the metallurgical industry. Hydrogen is also an important chemical raw material. For example, hydrogen can be used to produce ammonia and further produce fertilizers.
