High-purity hydrogen (H₂) for fuel cell applications, petroleum refining, ammonia production, and metal processing.

Hydrogen is a colorless, transparent, odorless, tasteless, and highly flammable gas at room temperature and pressure. As the lightest and most abundant element in the universe, it is insoluble in water and exhibits unique physical properties. Hydrogen serves as a versatile industrial gas and a key enabler of the clean energy transition, widely used in fuel cells for power generation, as a chemical feedstock for ammonia and methanol production, in petroleum refining (hydrocracking and hydrotreating), and as a reducing atmosphere for metal processing and semiconductor manufacturing. It is typically transported as a compressed gas or liquefied cryogenic liquid.
