Hi !
Well if you want to test electrolyzer designs and fiddle with it during some months until you get a tiny amount of H2, go with the electrical one .. It's the way to go in my opinion, because the probability that there is a method to increase the efficiency is high, but you have to find the caracteristics of the driving circuit that will provide the best gas output ..
Some here pretend to have done it, Bob Royce, AlaskaStar .. It's not clear what is the role of Thrival in all that, I think he's just fiddling with this.. And surely, the ones that knows how to do it don't want to give us the opportunity to test their work . . Go figure ! ..
And there is the method that really works but that consume Aluminum and tiny amounts of NaOH ..
I've done it and the method generates HUGE amount of H2 !! ..
I call it the chemicalyzer ..
You don't need Power Input .. You just have to design a leak-free unit that
is very sturdy with a mecanism to input Aluminum and Water ..
You need to keep separated the trash that the reaction will create from the NaOH/Water solution ..
The NaOH/Water will "eat" the Oxide Layer that creates on the Aluminum so AL will be exposed to Water and it will reform it's oxide layer by taking O from Water and letting out H2 from water . .
It is simple .. You mix NaOH and Water together, in a +20% concentration (- That's what I have done, you'll have to test -) and you drop Aluminum flakes or any Aluminum in the solution ..
I've used Aluminum Cans and Aluminum Foil and some Aluminum scrap, everything worked .. Than, the reaction takes some time to start, maybe 1-2 minutes to get a good amount of gas .. I think it's because the reaction is best at a certain temperature .. The reaction will cause heat in the unit, so you'll need to find a way to get the best Temperature Ratio ..
And if you put some of these units together, you have a HUGE amount of H2 ..
Oh, and the rate of consumption of AL is NOT that much ! .. I have a unit that worked for a week and 1 pound of AL wasn't all consumed .. Well it didn't work at full gas output, because it consumed some NaOH ..
Anyways, it takes about 6 KWh of power to generate 1 pound of Al (- I think it was 1 pound, have to verify -) .. So you might get some stored power out of this . .
Now the problem comes with implementation .. You'll have to find a way to regulate gas output before putting it in a Carb ..
Regulating the AL drop might do it .. but I would go for storing some amount of surplus H2 and injecting in a carb . .
