3. Available Gases
3.6 Hydrogen (H2)
Hydrogen is essential in aerospace as fuel for rocket engines, and energy supply to computers as well as life support systems in space. It is also used to improve plasma welding and cutting operations. Additionally, itis usually mixed with Argon to weld stainless steel and can be used as a propellant for any type vehicle. Hydrogen is also offered as a pure specialty gas under the brand ALPHAGAZ™, which is suitable for critical laboratory and analytic applications.
