Everyday uses of hydrogen in industry are numerous:

• Hydrogenation – adding hydrogen to liquid oils converts them to semisolid materials such as margarine, peanut butter, and shortening
• Chemical Processing – hydrogen is a necessary element in manufacturing ammonia through the Haber process and methanol in hydrodealkylation, hydrocracking, and hydrodesulphurization.
• Metal Production and Fabrication – hydrogen creates a protective atmosphere in high-temperature operations such as stainless steel manufacturing. Also mixed with other elements such as argon for welding applications.
• Pharmaceuticals – hydrogen is used to produce sorbitol, which is used in cosmetics, adhesives, surfactants, and vitamins A and C.
• Aerospace – hydrogen is the primary fuel that propels spacecraft. It is also used onboard to produce electricity and drinking water with fuel cells.
• Electronics – hydrogen is used to create a specially controlled atmosphere in the production of semiconductor circuits.
• Petroleum Recovery and Refinery – hydrogen is used to enhance the performance of petroleum products by removing organic sulfur from crude oil as well as to convert heavy crude to lighter, easier to refine, and more marketable products.
• Fuel Cells - hydrogen is the primary fuel used in fuel cells for electricity generation.
• Lifting Agent – hydrogen is lighter than air, therefore it may be contained in balloons .
