1.   Hydrogen is used extensively in industry for the production of ammonia.

2.   This may be explained by the fact that more hydrogen was used in a metabolism other than methanogenesis in these subjects even on the basal diet.

3.   And could you use hydrogen to run cars, for example?

4.   Another study is looking at how to develop a new rocket fuel using solid hydrogen and other light fuels with high energy output.

5.   Cheney was briefed yesterday on fuel cells, a technology in which electricity is produced using hydrogen.

6.   Fuel cells use hydrogen to create electricity.

7.   Fuel cells use hydrogen from various fossil fuels to drive an electrochemical reaction that produces electricity, with water the sole byproduct.

8.   Hydrogen principally is used today in the chemical industry and the space program.

9.   In October, the partnership decided to use hydrogen created from natural gas as the first fuel source to be tested in its demonstration vehicles.

10.   In the nearer term, hydrogen would be used in fuel cells for cars, trucks and industrial plants, just as it already provides power for orbiting spacecraft.
