Hydrogen fueled cars?

Question

I really don’t know, so I mean this in all honesty, Would a car ‘burning’ hydrogen not still put off ‘co2’ like anything else, its still ‘burning’ isn’t it? So why would this not add ‘greenhouse gases’

Answer 1

The burning of hydrogen does not produce CO2, because there is no carbon in the fuel to be burned.  But, the most efficient way to produce hydrogen is by steam reforming of hydrocarbons (which is the process used for almost all commercial scale hydrogen production) and this does produce CO2.

Answer 2

i have an audio link to a short interveiw with bob lazar

Answer 3

Hydrogen cars don't release CO2 their exhaust is water. Hydrogen cars don't actually "burn" anything, they utilize energy from oxygen bonding with the hydrogen to form water. I'm not exactly sure what really happens but its something like that but I do know for a fact that hydrogen cars do not release any type of CO2.

Answer 4

Both water and heat come from "burning" hydrogen.  Nothing chemically bad for the environment but the additional heat exhausted, on the projected scale of auto usage, is a bad thing.  

Hydrogen cars are not really zero emission, they will accelerate the greenhouse effect via heat.

Answer 5

Wonderful and Fearfuly made!

Hydrogen is a great option for the concept of free energy.     I built my first hydrogen cell about 5 years ago and now currently run 2 trucks, my home hot water heater, home stove and home generator on hydrogen for free with caught rain water and the help of a $10 solar panel.  I offer a step by step DIY guide to walk anyone interested threw the process. You can find it at http://www.agua-luna.com/hydrogen.html or you can email me.

There are basically 3 safe ways to make and use it... chemically, electrically and molecularly, the first 2 being easier so I'll only discuss them here. The fallowing steps were taking directly out of a DIY guide I offer to those who would like to run their vehicles or home on hydrogen safely. The entire guide is available at http://www.agua-luna.com/guides.html

    On demand h2 generators are a bit different from the Hollywood versions like seen Chain Reaction with Keanu Reeves, that tend to explode violently every time a film is being made. However when used in an on-demand system there is no storage of hydrogen and oxygen in its gas form, only liquid (water) and is only transformed into gas “on-demand” in small cylinder size amounts. It’s actually safer then gasoline as it doesn’t evaporate, creating explosive fumes in the tank like gas.

    Chemically

    1. You’ll need a 6inch x 1ft schedule 40 pvc pipe. With pvc cement glue a cap on the bottom and use a s***w on cap for the top. Drill a small hole (1/4inch or so) in the side close to the top, s******g in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).

    2. Now crunch up a couple aluminum cans (beer cans, soda cans etc) and drop them into the pvc pipe, along with a couple cups of lye (Red Devil drain opener has lye in it, some Clorox and Drano’s do to).

    3. Then simply add water, s***w on the top and wait a few minutes.

    What happens in simplicity is that aluminum and lye don’t really get along so they battle, and as always the innocent civilians (water H2O) that the most casualties, by giving up its hydrogen and oxygen. This then builds up in the void of the pipe and is ready to be vented into your engine, by opening the valve. You may need to start your engine on gas then switch it off after the hydrogen starts burning.

    Electrical is a bit easier then Chemically.

    1. Simply take a small solar panel 1.5 amps is what I use ($9 at harborfreight.com), connect the 2 wires from the panel +- to 2 conductors (carbon cores of batteries work well, just be careful removing it from the jacket), but any conductive material will work ie. Copper, aluminum, steel, etc.

    2. Drop the wires into a water tank (I use 55gal drums), make sure they don’t touch each other.

    3. Drill a small hole (1/4inch or so) in the side close to the top, s******g in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).

    4. Then simply add water, s***w on the top cap and wait.

    After a few hours tiny bubbles will form and rise off one conductor (that’s hydrogen) and even smaller bubbles that just looks like foam will rise off the other (oxygen). I don’t remember which likes the positive and which likes the neg hydrogen or the oxygen.

    The third method is more complicated and is what I use for my vehicles. It’s just a modified Joe’s Cell, there’s a step by step DIY guide available to walk you threw the process here http://www.agua-luna.com/hydrogen.html It also covers the other 2 methods described in more detail.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at http://www.agua-luna.com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Answer 6

There's a couple possiblilities here.  You can burn the hydrogen, but as there isn't any carbon, or oxygen, for that matter in it, it does not produce CO2.  Or, you can produce electrochemical energy by reactions with oxygen.  The byproduct of that, is water.  

It is phenomenally expensive to produce either type at this point, and distribution is not possible with our current infrastruction.  I think you won't see hydrogen vehicles on a large scale basis.  

Bio-diesel and ethanol are stored and pumped in pretty much the same way as regular gasoline and diesel fuel, so you'll see a very expensive trend in this direction for a while, before it becomes obvious that it isn't viable with the production methods currently in use.  

I saw an article recently about electric cars and distribution of changeable batteries and high speed chargers at gas stations.  No special storage, transport, or infrastructure changes required for that.  It could end up being the way of the future, with oil prices the way they are, especially if nuclear takes off, which it may have to, given the current consumption environment.  

Eventually, it will come down to nuclear power, or drilling our own oil.  Whichever the environmentalists hate the least.  Solar and wind are fine small scale, but they can't keep up with demand unless there's some major breakthroughs.  But I digress.  

Using hydrogen fuel does not produce CO2.  Producing hydrogen fuel does, at this point, but it may be to a smaller extent than burning petrol in the cars.

Mind you, there's no proven reason to believe that CO2 has any harmful effect on the environment.  But since you asked about it, I figured I'd answer.  

I'm all for nuclear, myself.  Freedom through fission!  Anyway, good luck with your hydrogen interest.

Answer 7

the fuel is nothing but Hydrogen(H2)

and its combustion would be

H2 + O2 = H2O(water)

as only product is water and nyhg else

hence no green house gases

and no pollution

Answer 8

because everything that comes out of the car is water vapor

Answer 9

And to add its obviously better for mother nature and reducing global warming.

Answer 10

The trick about hydrogen is that it doesn't occur free in nature in much quantity; you can't just go out and drill a hydrogen well.  Hydrogen has to be made using some other source of energy.

Right now, the major ways of producing hydrogen are by steam-reforming natural gas (CH4 + ½O2 + H2O -> CO2 + 3 H2) and gasifying coal and reforming the carbon monoxide in the syngas (CO + H2O -> CO2 + H2).  All of these processes yield carbon dioxide.

So no, burning hydrogen does not yield CO2.  But the making of the hydrogen does.

Answer 11

When burned in an engine, hydrogen produces effectively zero emissions; when powering a fuel cell, its only waste is water.

Answer 12

Hydrogen reacts with Oxygen to form water vapour. The reaction generates energy and water vapour. Since there is no carbon in Hydrogen, there is no Carbon Dioxide.
