Used as a power source, hydrogen gas fuels rockets and powers life-support systems and computers in space environments. It is also used for metal sintering and annealing.
As a heat treating furnace atmosphere, hydrogen reacts with oxygen to produce a bright finish on steel parts. It also makes an excellent industrial quench gas because of its high heat transfer properties. When used as an alternate fuel, hydrogen plays a key role in reducing undesirable emissions.
Our hydrogen is used to propel everything from land speed record-breaking vehicles, to fuel cell powered passenger cars, buses and forklifts.
Hydrogen for Fuel Cells
Hydrogen is essential in today’s refining industry for upgrading heavy crude oils into refined fuels, and helping to meet increasingly tight transportation fuel specifications.
Refinery Gas Processing
Used to enhance plasma welding and cutting operations, hydrogen gas is commonly mixed with argon for welding stainless steel.

For smaller, more specialized applications, we offer hydrogen in high-pressure gas cylinders or liquid containers in a variety of sizes.
If you require medium-range amounts of hydrogen, we offer bulk liquid deliveries that are made by truck and stored in hydrogen tanks located at your site. We also deliver hydrogen in high-pressure gas tube trailers to provide flexibility for supply pressure and flow rate.
Praxair maintains sophisticated hydrogen pipeline operations for large volume users in several key geographies with significant refining and chemical activity. We control and monitor each of our hydrogen pipelines to assure purity and to ensure that customers get the flow rate they want at the pressure they need.
As your supply needs grow beyond bulk, Praxair can provide small or large on-site hydrogen supply. Praxair designs, installs, owns, and operates every system, so you don't have to worry about maintenance. On-site plant sizes range from 9,000scfd (10 NCMH) to as as large as 135MMscfd (150,000 NCMH). Our plants, whether small or large can offer reliable supply that meets your exact specifications for purity, pressure and flow.
