In this sense, dhydrogène denotes the simplest and most abundant element in the universe, existing throughout space primarily as molecular hydrogen, while on Earth it is mainly present in compounds such as water and hydrocarbons rather than as a free gas under ordinary conditions.
Dihydrogen is a colorless, odorless, and highly flammable gas at room temperature. It has a molecular weight
Industrial production mainly relies on steam methane reforming and electrolysis of water, with growing interest in
Safety considerations emphasize that hydrogen is extremely flammable and can form explosive mixtures with air; leaks
