General FAQ |
| Question: Is a hydrogen powered vehicle like a hydrogen bomb? |
|
| Answer: No, a hydrogen bomb generated a tremendous amount of energy from the fusion of hydrogen atoms to form helium. A hydrogen powered vehicle uses a fuel cell or internal cumbustion engine to generate energy in a controlled and safe manner. |

| Question: Is hydrogen dangerous? |
|
| Answer: Pure hydrogen is indeed flammable, but due to its low atomic weight hydrogen tends to dissipate quickly if released from a storage vessel like a fuel tank in a vehicle. Also, hydrogen is non-toxic. Ultimately, hydrogen is no more dangerous than the chemicals we live with today and with appropriate public education and awareness on handling and use, hydrogen may prove to be safer than conventional fuels we use today. |

| Question: How does hydrogen compare to gasoline as a fuel? |
|
| Answer: By weight hydrogen has three times the energy content of gasoline, but by volume hydrogen is low in energy. Therefore, hydrogen stored onboard a vehicle must be kept under tremendous pressure or at very low temperatures. The energy generated from hydrogen run through a fuel cell is 2 to 3 times as efficient as burning gasoline in an internal combustion engine. Therefore, you may travel about twice as far per unit of fuel in a fuel cell vehicle powered by hydrogen than you will with internal combustion engine vehicle powered by gasoline. |

| Question: Where do we get hydrogen? |
|
| Answer: Hydrogen is the most abundant element in our universe although, here on Earth it is tied up in numerous everyday compounds all around us such as water(H2O). Today, the majority of hydrogen comes from using steam to strip the hydrogen out of natural gas in the presence of a metal-based catalyst. Unfortunately, in addition to hydrogen this process releases carbon dioxide, which is a gas that contributes to global warming. A goal of the hydrogen economy is to extract hydrogen from water by using electricity from renewable resources in the process of electrolysis. |
