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.
What else can I help you with?
Could the US reduce its use of oil by increasing use of nuclear power plants?
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.
Which is better new or old cars?
depends, old cars are based on power but new cars are based on technology like computers
Does the subway work when the power's out?
no the subway cars use electricity to run
Do cars also have DC motors?
yes car is using dc motor like in wipper / wipper pump motor a/c motor etc' and you can also use ac power by using a dc / ac inverter on your car and you plug your tv/pc/personal refgigerator etc' or even you power tools, you can buy that inverter at your nearest electronic or electrical shop. hope this messege helf you.
What are Nickel-metal hydride batteries used in?
the electric engines of hybrid cars. that's where the hybrid engine is getting its power from.
What fuel will cars run on in the future?
Many alternative fuels, and there can also be air-powered cars, hydrogen powered cars, electric cars, and many more. The best part about using air, hydrogen, and electricity to power cars is that it produces 0 carbon emissions.
Is there a different way to power your cars?
You can power cars through electricity or Hydrogen fuel cells (only available in california)
What does hydrogen power?
it powers something,i think it powers cars
Is using hydrogen as a fuel in cars?
Hydrogen can be used as fuel in carsbecause it don't cause any pollution
What are the benefits of hydrogen cars?
Some benefits of hydrogen vehicles are: less pollution, less dependence on foreign oil, less vehicle costs, and not having to purchase gasoline. These vehicles are great for the environment.
What are fuel-cell cars powered by?
Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and compressed hydrogen.
What fuels fuel cell cars?
Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and compressed hydrogen.
Is using hydrogen as a fuel in cars a chemical change?
To get Hydrogen as a fuel to be used in electric vehicles, the hydrogen combines with oxygen giving of 2 electrons which powers the application. The waste product is H20 (water!). If you want a simple yes or no, then the answer is Yes, because you are converting Hydrogen into Water to produce electricity.
How are hydrogen cars powered?
Generally, a Hydrogen powered car runs by using hydrogen and oxygen to create electricity in a fuel cell, which is then used to power an electric traction motor that runs the car. Direct ignition-engines are more difficult and dangerous to 'run'.
How does cars work?
=cars work by using a special power but not the same as house power or anything like that=
What is a challenge to using hydrogen as a fuel because hydrogen powered cars create less pollution than gasoline powered cars?
New fueling stations that can handle hydrogen would have to be built.
What is two ways hydrogen is used?
Hydrogen is used as a fuel in fuel cells to produce electricity for vehicles and stationary power applications. It is also used in the production of ammonia for fertilizers and in the petroleum refining industry to remove sulfur from fuels.
