Dihydrogen is an elemental molecule consisting of two Hydrogen atoms joined by a single bond. Generally named Hydrogen, it is a colorless, odorless gas. The vapors are lighter than air. It is flammable over a wide range of vapor/air concentrations. It has a role as an antioxidant, an electron donor, a fuel, a human metabolite and a member of food packaging gas. Hydrogen is used to make other chemicals.^[1]

All Products in the Value Chain of Hydrogen

Green	Hydrogen produced by electrolysis of water, using electricity from renewable sources like wind or solar. Zero CO2emissions are produced.
Blue	Hydrogen produced from fossil fuels (i.e., grey, black, or brown hydrogen) where CO2 is captured and either stored or repurposed.
Grey	Hydrogen extracted from natural gas using steam-methane reforming. This is the most common form of hydrogen production in the world today.
Purple Pink	Hydrogen produced by electrolysis using nuclear power.
Turquoise	Hydrogen produced by thermal splitting of methane (methane pyrolysis). Instead of CO2, solid carbon is produced.
Brown Black	Hydrogen extracted from coal using gasification.
Yellow	Hydrogen produced by electrolysis using grid electricity from various sources (e.e., renewables and fossil fuels).
White	Hydrogen produced as a byproduct of industrial processes. Also refers to hydrogen occurring in its (rare) natural form.
