Hydrogen uses


NASA has used hydrogen for years in space program. Hydrogen fuel lifts the space shuttle into orbit. Hydrogen batteries-called fuel cells-power the shuttle's electrical systems. The only by-product is pure water, which the crew uses as drinking water.

Hydrogen fuel cells (batteries) make electricity. They are very efficient, but expensive to build. Some day,small fuel cells could power electric cars. Large fuels could provide electricity in remote areas.

Because of the cost, hydrogen power plants won't be built for quite a while. Hydrogen may soon be added to natural gas, though, to reduce pollution from existing plants.

Soon hydrogen will be added to gasoline to boost performance and reduce pollution. Added just five percent hydrogen to gasoline can lower emissions by 30 to 40 percent.

An engine that burns pure hydrogen produces almost no pollution. It will probably be 20 years, though, before you can walk into your local car dealer and drive away in a hydrogen powered car.

Hydrogen would also be a great jet fuel. It's high in energy, so jets would need less fuel. And it's weights less than the fuel today, so jets could carry more cargo. It's also non-polluting. If the price of jet fuel continues to rise, you might see planes converting to hydrogen in the near future.
 

 
Before hydrogen can take its place in the U.S. energy picture, many new systems must be built. We will need systems to make hydrogen, store it and move it. And consumers will need the technology to use it.

The goal of the U.S. department of energy's Hydrogen program is for hydrogen to produce ten percent of our energy by the year 2030. Hydrogen will reduce our dependence on foreign oil and provide clean, renewable, energy for the future.
