The Truth About Hydrogen
Wild promises abound, but can the simplest element in the universe really power our homes, fuel our cars and reduce our contribution to global warming? PM crunches the numbers on the real hydrogen economy.

A fuel cell is an electrochemical energy conversion device. It produces electricity from various external quantities of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.
Fuel cells are different from batteries in that they consume reactant, which must be replenished, while batteries store electrical energy chemically in a closed system. Additionally, while the electrodes within a battery react and change as a battery is charged or discharged, a fuel cell's electrodes are catalytic and relatively stable.Many combinations of fuel and oxidant are possible. A hydrogen cell uses hydrogen as fuel and oxygen as oxidant. Other fuels include hydrocarbons and alcohols. |
| More than 2500 fuel cell systems have been installed all over the world — in hospitals, nursing homes, hotels, office buildings, schools, utility power plants - either connected to the electric grid to provide supplemental power and backup assurance for critical areas, or installed as a grid-independent generator for on-site service in areas that are inaccessible by power lines. Fuel cell power generation systems in operation today achieve 40 percent fuel-to-electricity efficiency utilizing hydrocarbon fuels. Since fuel cells operate silently, they reduce noise pollution as well as air pollution and when the fuel cell is sited near the point of use, its waste heat can be captured for beneficial purposes (cogeneration). In large-scale building systems, these fuel cell cogeneration systems can reduce facility energy service costs by 20% to 40% over conventional energy service and increase efficiency to 85 percent. |
Is it possible for hydrogen to compete with oil in a global market?
Hydrogen fuel can be implemented as a renewable energy medium with immense potential. When utilized properly, it has the potential to entirely replace fossil fuels altogether. Transforming our largely oil based economy, to a new hydrogen economy, which will provide sustainability throughout the 21st century, and beyond, for as long as the sun continues to shine.

Hydrogen is the simplest element known to man. Each atom of hydrogen has only one proton. It is also the most plentiful gas in the universe. Stars are made primarily of hydrogen.
The sun is basically a giant ball of hydrogen and helium gases. In the sun's core, hydrogen atoms combine to form helium atoms. This process—called fusion—gives off radiant energy.
This radiant energy sustains life on earth. It gives us light and makes plants grow. It makes the wind blow and rain fall. It is stored as chemical energy in fossil fuels. Most of the energy we use today came from the sun's radiant energy.
Hydrogen gas is lighter than air and, as a result, it rises in the atmosphere. This is why hydrogen as a gas (H2) is not found by itself on earth. It is found only in compound form with other elements. Hydrogen combined with oxygen, is water (H2O). Hydrogen combined with carbon, forms different compounds such as methane (CH4), coal, and petroleum. Hydrogen is also found in all growing things—biomass. It is also an abundant element in the earth's crust.
Hydrogen has the highest energy content of any common fuel by weight(about three times more than gasoline), but the lowest energy content by volume (about four times less than gasoline). It is the lightest element, and it is a gas at normal temperature and pressure. |
| FST Energy Demonstrates Product that Eliminates Fuel Cell Dependence on Bulky Hydrogen Cylinders
SAN FRANCISCO--July 27, 2006--FST Energy, Inc. (www.fstenergy.com), a hydrogen storage, transport, and distribution company, today announced a significant breakthrough for the emerging fuel cell market by eliminating the need for metal hydrogen storage cylinders. Read More.. |
Hydrogen Buses -
Over the last four years, more than 50 fuel cell buses have been demonstrated in North and South America, Europe, Asia and Australia. Fuel cells are highly efficient, so even if the hydrogen is produced from fossil fuels, fuel cell buses can reduce transit agencies’ CO2 emissions. And emissions are truly zero if the hydrogen is produced from renewable electricity, which greatly improves local air quality. Because the fuel cell system is so much quieter than a diesel engine, fuel cell buses significantly reduce noise pollution as well. |
Planes -
Fuel cells are an attractive option for aviation since they produce zero or low emissions and make barely any noise. The military is especially interested in this application because of the low noise, low thermal signature and ability to attain high altitude. Companies like Boeing are heavily involved in developing a fuel cell plane.

Top Of Pole Racks For 6 sq-75 Modules
These are brand new Top-of-Pole racks There are (3) Three racks available, take one or all your choice. One rack has been opened and looked at and the other two have never been out of the original boxes.
If you have Shell or Solar World modules, or if you are willing to re-drill the racks for other modules (the modules are about the same size as many other modules of this wattage range) you can have brand new Power-Fab racks at way less than wholesale! List Pricing on these racks are $920.00 each. Requires purchase of a new or used 6 inch schedule 40 mounting pipe (purchased locally). Schedule 40 pipe is 6.625 inches outside diameter, so the gimble fits over this size pipe only. Call Tom for mounting tips 888-826-0939. FOB Utah. Can ship UPS to your location, 1 rack is 4 boxes or can ship truck freight (Cheaper) if you want all three racks 499. ech plus freight.
