Under ordinary conditions, hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas composed of diatomic molecules. When hydrogen is generated from renewable sources, its production and use is part of a clean, cyclic process.

He was an English chemist and physicist who spent several years studying the properties of hydrogen and carbon dioxide. In 1776 he discovered that hydrogen was a separate substance. The ultimate goals of chemists studying Hydrogen are to produce cost-effective hydrogen from renewable energy sources and to make it available for widespread use as a clean energy carrier and fuel.
