H2

H₂, or molecular hydrogen, is a simple chemical compound composed of two hydrogen atoms bonded together. It is a colorless, odorless, and non-toxic gas that is the most abundant element in the universe. H₂ plays a vital role in various industries, such as fuel for clean energy, chemical manufacturing, and refining processes. Its high energy content and potential as a zero-emission fuel make it a promising option for reducing pollution and reliance on fossil fuels. In nature, it also occurs in small amounts and can be produced through natural or industrial processes.
