Ther is no cheap way to produce hydrogen gas. What ever energy you have, would be best spent to provide heat in the first place, because you will loose energy in the conversion.

Welcome to CR4 space clown.

The more information you can provide, the more we can help you.

We are a pragmatic lot here, firmly based in proven science, with literally many hundreds of thousands of years of practical experience. But we need something to go on. Please give us you situation, that is, what you have to work with, and, perhaps we can help.

Listen to Bricktop's #1 post. He speaks the absolute, clear, can't-be-changed-soon truth. As of today, hydrogen is more expensive than natural gas, propane, electric, coal, you name it. In order to make hydrogen, you must have electricity (current technologies) which has an average cost of about $33.00/million BTU (source: DOE, current on December 18). Even if you could make the hydrogen with 100% efficiency (you can't), that would be the cost of the hydrogen. Natural gas is half that. Propane, fuel oil, and kerosene are a little less than electricity. Wood and coal are a lot cheaper.

Location, location, it is all about location...

I agree that all common energy sources are cheaper than Hydrogen.

On the other hand, here in Quebec, electricity is far cheaper than petrol sources, and unless you cut your wood yourself and or use a very efficient wood burning scheme, there is not much to be gained.

Still, you would be at loss using our cheap electricity to produce hydrogen from water. Hydrogen/Oxygen bonds are just too strong.

If you have enough electricity to produce hydrogen for heating, you have enough for direct electrical heating.

Sciesis: the way that I been able to produce hydrogen is to Aline water molecule's once that was accomplished then split the molecule's with a sound board.but I do it a 110volts 4amps. and do not convert to Dc current that causes a lot of other problems.

Your reference to "wickum" in another post drew a blank.

When you find a cheaper way, forget about heating your shop... Put the hydrogen and oxygen through a fuel cell and sell the electricity. Save up the money and buy an over unity device and use the heat from the bearings to heat your shop.

What about using solar energy, converted to electricity by PV cells, then use hydrolysis to split into hydrogen and oxygen. That way, the cost is that of the PV cells and other equipment, but which can be amortized. The ongoing energy is free. What kind of equipment do you need to hydrolyze, and what pressures are required to contain and store the hydrogen?

chrisq288: at present we do not store the hydrogen we use the unit is design to produce the same amount that is being consumed. the type of equipment we use is call the wickum unit. its taken a great deal of time to get it right,as I said before the unit runs on 110 volts 4 amps.

Back in 2004, George Bush granted 1.2 Billion in Hydrogen research, which in my book is a massive amount of money, and what results has anyone seen, other than a rise in interest by individuals. Was this money used to research, or simply to control all available patents? Where are the results???? was the 1.2B completely wasted? Where are the spinoff technologies?

Wasted never. Paid consultants most likely got it , like back during the Synfuels days of the Carter Adm. , they were paid over 90% of the 26 Billion dollar budget. So, It would be in step with all other government programs, that the H2 money was well spent also ; don't you think ?

Forget H2 its a waste of time for the moment as the storage question and cost of splitting enough to do work is out of scale with needs. I say , Make methane , it worked for hunderds of years as the home / farm and some cities, main fuel very well.

Best Regards

Joe

Re: can anyone tell me the cheapest way to produce hydrogen gas?

The cheapest way to produce hydrogen gas is to strip the loose ones out of propane. There are several commercial producers of this equipment.

Since I assume throwing propane over your shoulder to get to hydrogen doesn't meet some unstated goal I'll throw out some more options:

1. Ebay build it yourself hydrogen generator instructions for electrolysis. Presumes REALLY cheap electricity. Solar panels?

2. Gasification techniques from the turn of the century allow almost any carbon containing stock (coal, wood, corn stalk) to be turned into "coal gas" - probably high hydrogen content.

eh, I'm out of ideas. A little help here?

Well, flatus is mostly hydrogen. Maybe use bacteria to convert corn into hydrogen.

Gordie.

BTW for those who would 'inform' me that flatus is mostly methane:

Not unless you're a farmer. Most people produce hydrogen, a bit of carbon dioxide, and swallowed air.

Maybe you should invest in methods to retain the heat as far as possible. (or recycle heat)

In a (machine) shop there may also be many sources of heat that can be utilized instead of disposing of it. (What type of shop do you have?)

Hendrik,yes your correct in storing heat,then recycled back to were it is needed,and I do the very thing that your reply has suggested.Still the question remains,the unit that I have developed will produce a cheap form of gas than acetylene for welding and heating metals.

If one can separate the hydrogen and oxygen by just looking at it it would be a winner. But unfortunately producing it will cost more than it is worth.

How? As a kid I did.

Drop a piece of zinc into an acid - very cheap , my dad were paying for it.

At school we connected the electrodes to a positive and negative pole. I saw the hydrogen coming off. I don't know were the electricity came from I think the school were getting it for free.

I once really overcharged a lead/acid battery and a lot of hydrogen were released. The battery were replaced by the supplier. still cheap.

It sounds like you have an excellent alternative to arc welding. Stick to welding and leave the heating to the HVAC people.

It will be a lot cheaper to use the electricity to heat your shop directly than to generate hydrogen for burning.

I have to agree with TVP here. Even if you could electrolyze water at 100% efficiency (doubtful), the ICE could never be as efficient as an electric motor.

The Correct way to do electrolysis is to use a PWM (pulse width modulator).

Use a 9-12 volt DC power source and connect the PWM and use stainless steel rods or stainless steel wire in the water tank. Then adjust the PWM until you get the maximum amont of Hydrogen and Oxygen bubbling. That's what I use in my car to produce HHO and then feed that to my air intake to get a mileage increase of 10-15%.

But, you can also use it to heat a shop or home.

did you ever thought of the safety hazards of using hydrogen gas we already have sufficient problems in in the acetelynes for welding, cutting (we have pipe lines running through our factory with a central generating station and we rarely use cylinders for it). This is already our prime identified hazard for OHSAS. Why do you want to use hydrogen for shop heating.

Hmm, does hydrogen spontaneously and explosively decompose at a few dozen PSI? Acetylene does. Is hydrogen poisonous? I can't remember, but I'm pretty sure acetylene is. Can you generate just as much acetylene as you want, where you want it with the flip of a switch? ...form water?

It sounds to me like space clown has a real winner here.

I don't understand why he's bothering himself with heating, though.

To Bricktop and the rest of you Guys who really know what is what:-

this Guy does not have any idea at all, so either you inform him from Chemistry 101 onwards, or you just say he is wasting his time and should rethink his project!!!

Which is what I feel I have started to do to a small degree with this post, hopefully......

The cheapest way to make hydrogen is reforming it from 103 proof alcohol. The problem comes from: the cost of the lab and the materials to make the reformer; The cost of the alcohol ( the major savings is to not remove much more than 51.5% of the water).

The reformer frees up 160% of the hydrogen from the alcohol (100% of the alcohol and 60% more from the water).

This DOE document has some cost targets, expressed in terms of equivalent gasoline prices. If I read it correctly, current cost is at, or above $4.00.

the DOE is smoking dope. The cost to manufacture H2 is more than twice the cost of the energy used to make it. Clown, give it up. My God son, you are making are consuming 440 watts, if the heater ran 24 hours per day, thats only $1.50. Your net energy released from burning the H2 is just under 200 watts. A hair dryer will put out more heat.

Don't worry. The whole topic is off-topic.

And hydrogen sulfide as well: that's what gives the gas its distinctive fragrance.

Did you say HYDROGEN sulfide? You may actually have his answer there. :-)

Nope, it's hydrogen. People produce hydrogen. Only people who spend a lot of time around livestock produce methane.

Hello S.C. ,

We always suggest to our clients that want nearly free gas, to produce their own methane and forget trying the production of hydrogen, on the non commercial scale. It's just not feasible .

Oh, there is some hydrogen in there too but, in a digester pond situation, that and most of the impurities are swept way by the pond digester water, most being metabolized in the water and you will make more useable gas this way, than what you will use, if your feeding the thing properly. A 10 foot deep pond digester should be a standard at every home place, with the room to operate one.

I Hope that helps you,

Best Regards.

because H2 isn't a fuel, now to you understand?
