Hydrogen cars usually run in one of two ways.

There are cars like the Honda FCX Clarity, which uses a compressed gas form of hydrogen. The hydrogen is converted into electricity inside the car by fuel cells, which in turn powers the cars. So, these car types would still be considered electric in part because that is what is really powering the car, it is just that the hydrogen is the source of the electricity, rather than having to plug in your car at the end of the day.

Then there are also cars like the BMW Hydrogen 7 Concept, which utilize the hydrogen via ICE (Internal Combustion Engine), the traditional engine type. The hydrogen, like gasoline, is used in the engine to power the car. The hydrogen in this case is a liquid form. Currently, BMW has given the Hydrogen 7 a modified V12 engine, which can use both gasoline and hydrogen at the same time.

There is no clear "better way" when it comes to hydrogen, it is relatively new to cars. Both produce water vapor as their only emissions though, and serve as an alternative fuel in the future, if the hydrogen can be produced in an efficient way.

How do you make a car run on hydrogen?

It's just called a modified engine. But the device used to convert hydrogen and oxygen into water is called a fuel cell, so that's probably what cars that run on hydrogen gas use to operate.


Is hydrogen combustible in car engines?

Yes, hydrogen is transferred into the power to move the car either by fuel cell (resulting in electricity) or a traditional ICE (Internal Combustion Engine). Either way, the end product is water vapor.


How does a Hydrogen powered car work?

Hydrogen gas reacts with oxygen gas to form water and gives off energy in the process. This energy, mostly in the form of heat, can be used as an energy source. Hydrogen fuel cells are specialized to react the hydrogen and oxygen in an optimal way so that maximum energy can be harnessed. The source of the energy is the hydrogen gas that is synthesized in a lab, usually by the electrolysis of water (which means running electrical energy through water causing it to separate into oxygen and hydrogen gas). The energy used to create the hydrogen gas can come from many sources including fossil fuels, solar, hydroelectric, etc.


About how many years does it take for a star to run out of its fuel hydrogen?

It typically takes around 10 billion years for a star like the sun to consume all its hydrogen fuel and enter a different phase of its life cycle. The exact duration can vary depending on the size and type of the star.


Why does a star's hydrogen supply run out?

A star's hydrogen supply runs out because of nuclear fusion in its core. As hydrogen is fused into heavier elements like helium, the star's core temperature increases, causing it to expand and cool. Eventually, the core runs out of hydrogen to fuse, leading to the star's evolution into a different phase.

How can you make your car run on water?

You can make a car run on water if you diffuse oxygen and hydrogen and use hydrogen in your internal combustion engine!But then it is not running on water which was the question. It is running on Hydrogen. So the answer is still NO, you cannot run a car on water.


How to work hydrogen car?

CArs will not run efficiently on hydrogen gas


Is it possible to run a car on water?

no. But they are working on it. They are developing a process to separate the hydrogen from H2O. An engine can run on hydrogen.


Could a car run on hydrogen?

no because it needs fuel and hydrogen does not have everything in the combustion triangle


Is there a car that runs on water?

They are working on that. They have machines that can separate the hydrogen from the oxygen. An automobile can run on hydrogen.


How much hydrogen is needed to run a car engine?

hydrogen has three times the potential energy of gas, but it has four times the volume. It would take less hydrogen by weight but it would take more by volume to run a car


Can a car be run on hydrogen gas?

There are a couple ways you could run a car on hydrogen. First is to just burn the hydrogen, but you would need a LOT of hydrogen to power a car--about 2 cubic feet of it at 3000 psi (which is the pressure in a tank from a welding shop) per each gallon of gasoline you don't want to use. The other is to make an electric car with a hydrogen-powered fuel cell.


Can a car run on hydrogen gas?

Yes, they can but most cars don't.

Is it legal to run a hydrogen car in the US?

Yes, it is legal to run a hydrogen car in the US. However, access to hydrogen fueling stations may be limited compared to gasoline or electric charging stations. Currently, there are hydrogen fueling stations primarily in California with plans for expansion to other states.
