Storing large amount of hydrogen to fuel cell car Is there a tendency for the car to become a hidden car bomb?

Question

we know that hydrogen gas is very volatile and even a small spark can ignite it and the reaction is a very violent explosion. Is this the problem while hydrogen technology is not advancing. Try look at the past. The one that happened to the hindenburg disaster. the hindenburg suddenly ignite and rapidly burned and all the crew where died in that accident. the hydrogen has really many negative feed backs.

Answer 1

I know I'm wasting my time answering this question but.....the truth needs to be defended at all times and all places.

No!  Hydrogen's energy density by volume makes it a very poor bomb material.  Sure the 'H' bomb is a great bomb but the process is thermal nuclear fusion which is carried out at temperatures 3 orders of magnitude greater than hydrogen combustion.

Hydrogen is less volatile than gasoline, it does burn through a wider range of air fuel mixtures though.

Hydrogen technology is advancing all around the world.   Many very good hydrogen production methods and storage practices where developed over a hundred years ago.

Please look at the past, watch the hindenburg film, watch the hydrogen gas go up, watch the skin and diesel fuel fall and burn.  Also, get it right 97 people were on the Hindenburg when it burned and 62 of them survived.  2 who did not where burned and most who did not make it jumped out or fell to their deaths.   The survivors apparently rode down with the descending craft and ran away to safety.

Where did you learn all these incorrect notions you are spreading?   Hydrogen does need to be handled with care just like any fuel product.   Hydrogen may not be the fuel for you but it is a wonderful option to gasoline.

Answer 2

Not just the Hindenburg, look at what happened to the Space Shuttle Challenger.  Hydrogen also leaks.  Look how much time NASA engineers spend finding leaks that delay the launches.  Imagine your local shop trying to chance down hydrogen leaks.  Imagine the cost!!!!

No, hydrogen isn't the answer - Nuclear Batteries are!

Answer 3

let me start off by saying Hydrogen is a great option for the concept of free energy.     I built my first hydrogen cell about 5 years ago. Have converted over 50 vehicles in the last 10 years (gydrogen and EV) and now currently run 2 trucks (and another EV), 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 www agua-luna com 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 www agua-luna com

    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. the following were actually taken out of my $5 guide available at www agua-luna com

    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 www agua-luna com

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  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 4

Hydrogen, being such a light element, burned up in the air over the Hindenburg.  It was the burning magnesium paint on the cover of the blimp that destroyed it.

There are several ways to counteract the perceived "Hindenburg effect."  Researchers at the Univ. of Bath (England) have discovered that a compound of 6 rhodium atoms and 12 hydrogen atoms will store two extra hydrogen atoms at room temperature and normal atmospheric pressure.  Apply an electric current and the extra atmos split off, ready to power a car.

ECD Ovonics is working on carrying hydrogen in solid form in tanks filed with powered metal.

Energy Conversion Devices is also working on carrying hydrogen in metal hydride solid pellets.

In its Corporate Citizenship Report for 2007, ExxonMobil says they are conducting research and development of an on-vehicle hydrogen production system, which has the potential to improve vehicle efficiency by up to 80% while improving safety and eliminating the need for a hydrogen distribution infrastructure.

I sure hope Exxon is not lying to us.

Answer 5

Hydrogen is hard to store without leakage, and to store it we have to choose a storage medium that allows a lot of it to be stored in a compact space.

There are metal lattice structures that can store hydrogen in a way that it will not expand rapidly should the container be broken. This will still burn, much as will gasoline, but cleaner.

When there are leaks, it is best those leaks not be contained, as in a garage, where a large volume of hydrogen and oxygen get together.

If we attempt to merely compress hydrogen into a strong, thick steel chamber, we have a chamber which, on rupture will cause a lot of damage, regardless of burning. We would like to make accidents impossible for such vehicles.

But, hydrogen released from a very high pressure chamber is extremely cold, cold enough to kill by being cold. And by being extremely cold it does inhibit combustion.

Hindenberg does not disprove that statement. It was not a high pressure container. Its hydrogen was at air temperature, and oozing out through the skin. It also did not explode, it just burned, albeit with a poof when it started.

This is similar to liquid propane which when poured onto the ground is very hard to light on fire. It is just so cold!

The cloud as it evaporates does become combustible, and even the puddle of propane on the ground will support combustion,

If we use hydrogen it should not be in a container inside the vehicle where it can collect.
