Hydrogen from Renewable Resources
Hydrogen is the simplest and most abundant element in the universe. On Earth it is found combined with other elements to form things like water (H₂O), and many organic compounds, such as the hydrocarbons that make up fuels (like gasoline, natural gas, methanol, and propane). In its pure form, hydrogen is a high-energy fuel that, for example, is used for launching rockets into space.

Fuel cells can be made to produce electricity with no noise and emit only pure water.

Every major automobile manufacturer is currently researching fuel cell technology, including the fuel cell hybrid concept vehicle by Toyota.

     Renewable hydrogen may be used in stationary fuel cells to produce heat and electricity for homes and buildings and in mobile applications to power vehicles. A fuel cell combines hydrogen with oxygen from the air, and their only byproduct is pure water. They can be thought of as batteries that use hydrogen to create an electric charge. Fuel cells run on pure hydrogen or can reform the hydrogen found in other liquid or gaseous fuels. They can be made in any size to provide electric energy for appliances, cars, houses, hospitals, and even whole neighborhoods. All the major car manufacturers are currently researching and designing fuel-cell-driven electric vehicles to be on the market within the next decade or so.
