What is Hydrogen?

Hydrogen (H₂) is a highly combustible gas produced by separating it from water and fossil fuels. We offer hydrogen in a variety of supply modes for several applications.

We offer compressed and liquid hydrogen in various grades specific to different applications, such as:
• A welding gas for stainless steel
• An aid in processing crude oil
• A carrier gas in gas chromatography
• A propulsion gas in rocketry

Industrial Applications

Manufacturing & Metal Fabrication
Often mixed with argon, hydrogen is used for welding and cutting stainless steel.

Chemical

In refineries, hydrogen is used to process crude oil into refined oils, such as gasoline and diesel, and to remove contaminants. Hydrogen is also essential in chemical processing such as creating sulfuric and hydrochloric acids.

Automotive
Hydrogen has become an ideal alternative energy source because of its tendency to produce lower unwanted emissions. Today, hydrogen fuel cell technology is being developed to power various vehicles like buses and industrial machinery.

Aerospace & Defense
Hydrogen gas is essential for rocket propulsion as well as powering and maintaining spacecrafts. It’s also becoming a popular alternative to fossil fuels used to support internal furnace combustion when manufacturing turbines and jet engines.

Primary Materials
Glass manufacturers rely on hydrogen to create a pristine furnace flame that produces less emissions, resulting in the production of cleaner and clearer glass.

Analytical Chemistry
Hydrogen is sometimes used instead of helium as the carrier gas in gas chromatography (GC).

Supply Modes

High-pressure & Liquid Cylinders
We offer hydrogen in high-pressure gas cylinders and liquid dewars—available in a variety of sizes—to meet any and all low-volume needs.

MicroBulk
For those who have outgrown cylinders and dewars but lack the space for bulk storage, we offer hydrogen through Airgas MicroBulk—a safe, clean and efficient solution for higher-volume users.

Bulk Deliveries
Hydrogen is also available in bulk gas and liquid delivery—as well as in a full range of purities and tank sizes.

Pipeline
If you regularly consume gas in large volumes, your needs might be best fulfilled with our pipeline supply systems—a more economical and reliable option to other supply modes.
