The Role of Hydrogen in the World Economy

ByRyutaro Hino, Kazuaki Matsui, Xing L. Yan

Hydrogen, though the most abundant element in the luminous universe (helium comes in distant second), is rarely found on Earth.

Notable compounds containing hydrogen include organic matters and water. In fact, the oceans are the largest terrestrial reservoir of hydrogen.
