Electrolysis Hydrogen sepperation,from H2O?

Question

Does anyone know where to find the best technology,for that process and the names of individuals who developed system using less energy to derive the Hydrogen,than that is produced. Not extracted from natural gas,but from water?

Answer 1

Not sure I believe it, but http://Keelynet.com might have what you're looking for.

Answer 2

No  matter how efficient you desire this process to be, you just can't get more energy out of this process than you put into it.

It takes more energy to break up water into hydrogen gas and oxygen than you get when they combine.

Answer 3

Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water. This electrolytic process is used in some industrial applications when hydrogen is needed.

An electrical power source is connected to two electrodes, or two plates, (typically made from some inert metal such as platinum or stainless steel) which are placed in the water. Hydrogen will appear at the cathode (the negatively charged electrode, where electrons are pumped into the water), and oxygen will appear at the anode (the positively charged electrode). The generated amount of hydrogen is twice the amount of oxygen, and both are proportional to the total electrical charge that was sent through the water.

Electrolysis of pure water is very slow, and can only occur due to the self-ionization of water. Pure water has an electrical conductivity about one millionth that of seawater. It is sped up dramatically by adding an electrolyte (such as a salt, an acid or a base).

Historically, the first known electrolysis of water was done by William Nicholson (chemist) and Anthony Carlisle in about 1800.

In the water at the negatively charged cathode, a reduction reaction takes place, with electrons (e−) from the cathode being given to hydrogen cations to form hydrogen gas:

Cathode (reduction): 2H2O(l) + 2e− → H2(g) + 2OH−(aq);    

At the positively charged anode, an oxidation reaction occurs, generating oxygen gas and giving electrons to the anode to complete the circuit:

Anode (oxidation): 2H2O(l) → O2(g) + 4H+(aq) + 4e−;    

Combining these two reactions yields the overall decomposition of water into oxygen and hydrogen:

Overall reaction: 2H2O(l) → 2H2(g) + O2(g)

The number of hydrogen molecules produced is thus twice the number of oxygen molecules. Assuming equal temperature and pressure for both gases, the produced hydrogen gas has therefore twice the volume of the produced oxygen gas. The number of electrons pushed through the water is twice the number of generated hydrogen molecules and four times the number of generated oxygen molecules.

Answer 4

You cannot produce hydrogen and oxygen from water using less energy than you get out of the hydrogen as a fuel.  This would be a perpetual motion machine and is forbidden by thermodynamics.  

It is simply impossible to do that, both in theory and in practice.  If it was possible, we could have plants generating electricity out of nothing.

Of course you've heard about it.  History has so many stories of people who invented perpetual motion machines and were killed to suppress them.  Conspiracy theories o' plenty.  

It is total bull, but this doesn't stop there from being new stories like this.
