How can Hydrogen be used to power a car?

Answer 1

Yes it is used in Iceland

Answer 2

because it is being already used.... hydrogen is flammable and you can convert that energy to move your vehicle. but i think it is not safe to use hydrogen as fuel since its highly, highly flammable.

Hydrogen (H2) releases energy when it is combined with oxygen; however in practice, production of hydrogen from water requires more energy than is released when the hydrogen is used as fuel.

Free hydrogen does not occur naturally, and thus it must be generated by electrolysis of water or another method. A reduction in carbon dioxide emission connected with hydrogen fuel is directly achieved only if the energy used to make hydrogen is obtained from non carbon-based sources. Nowadays (2010) the majority of hydrogen produced on earth comes from fossil fuels.

• hydrogen is not freely available
• hydrogen is a gas at most temperatures, and particularly difficult to handle
• hydrogen is more dangerous than most substances; equipment owned by consumers would have to be checked periodically
• hydrogen production requires resources, and ultimately leads to energy loss.

hydrogen is an energy carrier, not a primary energy source

Answer 3

Hydrogen is a very powerful fuel that is also the basis of what we already use as far as fuel goes. It is the separation of these hydrogen atoms from the fossil fuel that is the source of our energy. Powering automobiles from hydrogen would be very easy, although fuel tanks would be mounted on the top of the cars for safety reasons.


The downside of hydrogen fuel is that it is far from being a green fuel as advertised. Virtually all hydrogen is generated from natural gas and the byproduct is sent into the atmosphere. Net result is that you have a car fueled by natural gas when you are using hydrogen.

Answer 4

Hydrogen has the potential for providing a clean, efficient fuel source. This raises the question, how is it used? There are two processes that can be used to take hydrogen fuel and create useful work, combustion and in fuel cells. Combustion simply uses the hydrogen in an internal combustion engine or gas turbine instead of a hydrocarbon, like gasoline or jet fuel. A fuel cell is an electrochemical device and is a big reason hydrogen is seen a great potential fuel source.
