There are currently no hydrogen powered cars commercially available. These cars would be far from green in any event because of the way we make hydrogen currently. Hydrogen is currently made by stripping hydrogen from natural gas and venting the rest of the material to the air.

How much does pure hydrogen peroxide the fuel cost?
Hydrogen Peroxide is not a fuel. It is an oxidising agent. Chemical formula H2O2.
How much does a hydrogen car cost?
The Honda Clarity cost $300,000 each, but hydrogen fuel cells are expensive to produce and some are fragile.
If you electrolyse 1 gallon of water into hydrogen and then run the hydrogen through a fuel cell how much waste water will the fuel cell generate?
The fuel cell will generate about 1 gallon of waste water. The reaction of hydrogen combining with oxygen in the fuel cell produces water as a byproduct. Since the hydrogen generated from electrolyzing 1 gallon of water would similarly combine with oxygen in the fuel cell to produce water, the amount of waste water will be approximately equal to the original volume of water electrolyzed.
How much does a hydrogen fuel cell car cost?

How much less carbon dioxide do fuel cell cars emit?
Fuel cell cars use hydrogen to drive the fuel cell in the car which generates electricity. The only emissions are water and heat. No carbon dioxide at all. (The production of the hydrogen will have a carbon footprint, unless it was produced using renewable energy.)
How much hydrogen does it take to drive a car?
The amount of hydrogen needed to drive a hydrogen fuel cell car varies based on the car model and its fuel efficiency. On average, a hydrogen fuel cell car may require around 1 to 1.5 kilograms of hydrogen per 100 kilometers.
How much does the fuel on a space shuttle cost?
The fuel used by the Space Shuttle, known as liquid hydrogen and liquid oxygen, cost about $1.5 million per launch. This cost is just for the fuel itself and does not include other expenses associated with the launch.
How much do fuel cells cost?
One company commercially offers fuel cell power plants for about $3,000 per kilowatt.
How does the reaction of hydrogen and oxygen to produce energy in a fuel cell differ from their interaction during the direct combustion of hydrogen and oxygen?
In a fuel cell, the reaction of hydrogen and oxygen occurs electrochemically, producing electricity as a byproduct. This process is more efficient and produces less waste compared to direct combustion of hydrogen and oxygen, which releases energy in the form of heat without generating electricity. Fuel cells offer a cleaner and more controlled way to harness energy from hydrogen compared to combustion.
Which is larger a living cell or an atom of hydrogen?
A living cell is much larger than an atom of hydrogen. A living cell can be as much 10,000 times larger in size compared to a single hydrogen atom.
How much hydrogen will be required to produce on 1 kw?
To generate 1 kW of power using hydrogen fuel cells, approximately 0.1 kg to 0.2 kg of hydrogen would be required. The exact amount can vary depending on the efficiency of the fuel cell system and other operating conditions.
How does a fuel cell store electricity?
Fuels cells do not actually store electricity. They generate it instead, using hydrogen and oxygen as 'fuel'. The oxygen is atmospheric, the hydrogen must be stored under pressure and delivered to the cell through piping. So it's hydrogen that is being 'stored', not electricity as in a battery. Inside the fuel cell, atoms of hydrogen and oxygen combine into water across a special membrane which produces electricity from the resulting energy of chemical combination of the atoms. The "exhaust" of a fuel cell is therefore pure water, making them very 'green' to operate. The problem is producing hydrogen is a green manner - much harder to do, unless you're a plant with chlorophyll that can do photosynthesis using sunlight, the ultimate green technology. Another problem is storing and distributing hydrogen gas under pressure. It is very dangerous in some ways, remember the Hindenburg!
