Hydrogen can link today's fossil-based energy supply with the renewable energy of tomorrow.

Hydrogen is the most abundant element in the universe and the lightest gas known. It is colorless, odorless, tasteless, and nontoxic at room temperature and pressure.

Hydrogen contains more useful energy per pound than any other fuel. This means hydrogen is more efficient on a weight basis than any of the fuels currently used in air or ground transportation.
