Hydrogen (H2) is the simplest and most abundant element in the universe. It is a colorless, odorless, and tasteless gas that is lighter than air. Hydrogen is a non-toxic and flammable gas. These properties make it a useful gas for a variety of industrial and commercial applications.

Hydrogen gas is used in a wide range of applications, including:

• Industrial: Hydrogen gas is used in the production of ammonia, fertilizers, and methanol. It is also used in the refining of petroleum and the production of synthetic fuels.
• Energy: Hydrogen gas is a potential clean energy source. It can be used to generate electricity in fuel cells and turbines. Hydrogen gas can also be used as a fuel for vehicles and other transportation applications.
• Aerospace: Hydrogen gas is used as a fuel for rockets and other spacecraft.
• Welding: Hydrogen gas is used as a shielding gas in welding operations to protect the metal from oxidation and contamination.
• Food and beverage: Hydrogen gas is used in the processing of food and beverages. For example, it is used to hydrogenate fats and oils and to produce carbonated beverages.

Hydrogen gas is used in a wide range of industries, including:

• Industrial: Chemical industry, fertilizer industry, petroleum industry, steel industry, glass industry
• Energy: Power generation, transportation, renewable energy
• Aerospace: Rocketry, space exploration
• Welding: Metal fabrication, construction
• Food and beverage: Food processing, beverage production

Purity of Hydrogen Gas

Hydrogen gas is available in a variety of purity grades, depending on the application. The most common purity grades are:

• Commercial grade: 99.9% purity
• Research grade: 99.999% purity
• Ultra high purity (UHP): 99.9999% purity

UHP hydrogen is required for some applications, such as semiconductor manufacturing and fuel cells.

Hydrogen gas is typically supplied in cylinders, bulk tanks, and liquid tankers. The most appropriate supply option depends on the volume of hydrogen required and the application.

• Cylinders: Cylinders are the most common way to supply hydrogen for small-volume applications. They are available in a variety of sizes and purity grades.
• Bulk tanks: Bulk tanks are a good option for medium- to large-volume applications. They can be installed on-site and refilled by a gas supplier.
• Liquid tankers: Liquid tankers are used to supply hydrogen for very large-volume applications, such as fertilizer production and hydrogen refueling stations.
