The Energy Economy : Big Oil's Hydrogen Future
An article in Forbes magazine describes how natural gas may well become the cleanest, cheapest, and most common source of creating hydrogen for fuel cell cars. Natural gas is the cleanest of all fossil fuels, since it contains one carbon and four hydrogen atoms per molecule. That molecular structure also means that hydrogen can be produced cheaply from natural gas using a process known as “steam reformation,” which separates the carbon from the hydrogen. Natural gas’s wide availability, coupled with its suitability as a hydrogen source, means the gas is likely to become indispensable in producing hydrogen for fuel cell cars, which run on an electrochemical reaction that occurs when hydrogen is used as a fuel and oxygen as an oxidant.

Fuel Cells 2000
Fuel cells run on hydrogen, the simplest element and most plentiful gas in the universe. Hydrogen is colorless, odorless and tasteless. Each hydrogen molecule has two atoms of hydrogen, which accounts for the H 2 we often see. Hydrogen is the lightest element, with a density of 0.08988 grams per liter at standard pressure, yet it has the highest energy content per unit weight of all the fuels – 52,000 Btu/lb, or three times the energy of a pound of gasoline.
Hydrogen is never found alone on earth — it is always combined with other elements such as oxygen and carbon. Hydrogen can be extracted from virtually any hydrogen compound and is the ultimate clean energy carrier. It is safe to manufacture. And hydrogen's chemical energy can be harnessed in pollution-free ways.

National Geographic's Fuel Cells
Energy Source of the Future. According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of devices we use every day. A fuel cell is a device that uses a source of fuel, such as hydrogen, and an oxidant to create electricity from an electrochemical process.
National Hydrogen Association
Hydrogen fuel is on the brink of becoming a common and affordable source of energy for powering homes, vehicles, and industry. The National Hydrogen Association (NHA) is leading the transition from a fossil fuel-based energy infrastructure to a hydrogen-based one. Since its inception, the National Hydrogen Association, through its members, has guided the hydrogen community’s efforts to create a shared vision for the hydrogen energy infrastructure.

Running on Vapors
Honda Motor chose a good week to introduce its new hydrogen-powered car. With gas prices rising above $4 a gallon, we could hardly be more eager for an alternative energy source, especially one that claims to have no bad effects on the environment. A car powered by a ubiquitous, inexhaustible gas that emits nothing worse than water. New York Times Editorial, June 20, 2008.
