The Case of Hydrogen Technology

The hydrogen atom is the smallest and hghtest of all elements and also the most abundant element of the universe (75% of the visible mass of the universe is composed of hydrogen). It is found in a large variety of compounds such as in water, hydrocarbons such as methane, and biomass, but it is rarely found as a diatomic molecule of Hj. When this flammable gas is burned in oxygen, it forms water and also releases energy. [Pg.284]

Hydrogen is mostly produced from natural gas or coal through reforming with steam to produce syngas—a mixture of carbon monoxide (CO), hydrogen (H ), carbon dioxide (CO ), and water vapor (H O). It can also be formed by the electrolysis [Pg.284]
