Yes it is used in Iceland
Yes, dramatically. Especially if we switched to hydrogen fuel cell cars and produced the hydrogen in the nuclear power plants by direct thermal conversion without generation of electricity.
Before I list the advantages and disadvantages, it is important to note that Hydrogen is simply a medium with which to store energy, it is NOT an energy source, such as wood, gasoline, or atomic energy. The reason for this, is that Hydrogen does not exist in nature in large quantities, except in molecular compounds of one form or another... thus, to get Hydrogen, you must first extract the Hydrogen atoms from another molecular compound, such as water (Which contains Hydrogen and Oxygen) or even from Gasoline (which contains Hydrogen, Carbon, and Oxygen). In fact, a gallon of gasoline even contains more Hydrogen than a gallon of Liquid Hydrogen. Thus, it requires us to spend energy to create hydrogen to use in a fuel cell or combustion engine, unlike naturally occurring fuel sources like Wood, which grow/form on their own and only require us to release the energy through burning it (or splitting the atom like in Nuclear Fission). Gasoline is considered a fuel source because even though it needs to be refined, the energy it provides is greater than the energy it takes to refine it. The same is not true for Hydrogen. Some of the advantages of Hydrogen: -It no longer requires us to be reliant on Gasoline as an energy source. -It burns MUCH cleaner than other fuels, since it's only by-product is water. -In Fuel Cell use, it requires no combustion, which means fewer moving parts that can break in the engine. -It is in a small list of fuels which are: widely available, stable enough to be transported safely, and has a sufficient energy density so the fuel tank does not need to be larger than the rest of the vehicle. -Hydrogen can be created wherever it is needed, so you will no longer need to "Ship" it from the refinery to the gas station. Gas stations could simply have their own generators on-site, allowing them to ship stable liquids like water to extract the Hydrogen from. Some of the dis-advantages of Hydrogen: -It takes more power to create it than it generates, so the power needs to come from somewhere else, which can be hydroelectric, coal, solar, geothermal, etc. -Its energy density is significantly lower than gasoline, so you need a larger fuel tank to generate the same amount of power. -Much like gasoline, it is flammable, but can be explosive if mixed with enough oxygen, so the fuel tank must be protected extremely well. -The fuel infrastructure in most countries is not set up for Hydrogen, so gasoline stations would need to be converted in large numbers, quickly.
The SCRAMjet was a type of engine that could "suck" the Hydrogen & Oxygen from the air to make a fuel source. This mean it could last forever.
The international space station makes use of solar power.
Water is the benefit of a hydrogen fuel cell ;)
The fuel cell hydrogen is one of the two gasses, that are created by the seperations of a water molecule H2O. A water molecule consists of H - hydrogen, and O - oxygen. A fuel cell hydrogen is the gas created by the separation of a water molecule with the help of a fuel cell.
There are no commercially available hydrogen fueled cars.
No. Hydrogen fuel cell is not a title. You would only capitalize hydrogen if it was at the beginning of a sentence, as I did with this one. Otherwise, you would say 'hydrogen fuel cell'.
No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
yes it type of fuel
Hydrogen Fuel Cell converts the thermal energy released directly into electrical energy.. This fuel cell was used in the Apollo Programe. It also produces water.....
Hydrogen fuel cell cars seem to be the wave of the future. This website gives you links to all of the dealers with available hydrogen fuel cell cars: http://www.fueleconomy.gov/feg/fcv_links.shtml

The fuel for a cell is made up of oxygen and hydrogen. The chemical energy produced by the two is what is converted to serve as fuel for the cell.
Hydrogen gas
Water.
