Hydrogen's Job
~Below are the uses for hydrogen in our life one Earth:
- The fire that destroyed the Hindenburg back in 1937 gave hydrogen a misleading reputation. Hydrogen was used to keep the airship buoyant, but hydrogen did not cause the fire. NASA scientists have found that the Hindenburg's outer shell was coated with a compound similar to what is now used in solid rocket fuel. When the ship docked, an electrical charge ignited the coating. Hydrogen, as a fuel, was not the cause of the tragedy.commercial fixation of nitrogen from the air in the Haber ammonia process
- hydrogenation of fats and oils
- methanol production, in hydrodealkylation, hydrocracking, and hydrodesulphurization
- rocket fuel
- welding
- production of hydrochloric acid
- reduction of metallic ores
- for filling balloons (hydrogen gas much lighter than air; however it ignites easily)
- liquid H2 is important in cryogenics and in the study of superconductivity since its melting point is only just above absolute zero
~Below information are from Hydrogen Highway
- The lightest and most common element in the universe, hydrogen has been safely used for decades in industrial applications. Currently, over 9 million tons of hydrogen are produced in the U.S. each year and 3.2 trillion cubic feet are used to make many common products. They include glass, margarine, soap, vitamins, peanut butter, toothpaste and almost all metal products. Hydrogen has been used as a fuel since the 1950s by the National Aeronautics Space Administration (NASA) in the U.S. space program.
- Hydrogen has another use - one that can help our nation reduce its consumption of fossil fuels. Hydrogen can be used to power fuel cell vehicles. When combined with oxygen in a fuel cell, hydrogen generates electricity used by the vehicle's clean electric motor to create a smooth, quiet ride - and the only emission from the tailpipe is water vapor.
- Hydrogen is an excellent vehicle fuel for many reasons. The U.S. Department of Energy compares hydrogen very favorably to other fuels. Hydrogen is not toxic, poisonous or corrosive. As a result of hydrogen's benign nature, it doesn't harm the environment or public health. If hydrogen were to leak it would disperse into the air almost immediately because it is so light. Contrast that with the effects of oil and gasoline spills, and it's easy to see why hydrogen offers such an exciting future!
