Blue fuel Systems H2o gas Great stuff Steve .....I think that if you have access to double valve tank one on the top and the other in the bottom , in this way you connect the inlet Hydrogen connection to the top valve and connect the purity analyzer to the bottom valve and when you reach the right purity you just close the bottom valve . That is 100% safe because the Nitrogen and Oxygen are heavy than the Hydrogen and you can drain the condensate water from the tank in the same time so you catch 3 rabbit's with one shot . Hopefully my idea will help your Amazing job .
Good stuff, I'd bet that would also help maintain the structural integrity of the tank. The internal pressure pushing evenly across the metal helps keep the tank rigid (think of how unopened soda cans can support 100+ pounds) so keeping it pressurized could prevent it from weakening or imploding after repeated vacuum/pressure cycles
You seem to have most of it sorted out quite well but what I’m concerned with is you must bear in mind the weight of oxygen and hydrogen therefore you can clear your system of oxygen far better
@Steve - Appreciate the video. We do vacuum distillation, and you can pull down that big tank in less then a few minutes no problem with a cheap little 4 CFM vacuum from ebay, for under $100.
When you connected the tank hose fitting to the output, there was a hiss of air rushing into the evacuated hose, that means you are mixing air and hydrogen, very dangerous. Also, attaching/removing the fittings might create a spark if they are not rated for flammable gases. It might be better to fill the tank with another inert gas like argon to dilute the inevitable air that comes in. If you fill with nitrogen as others suggested, you might end up making some NH3 (ammonia), look up the "Haber process". Fun fact: liquid ammonia and liquid hydrogen contain the same mass of hydrogen per unit volume, and cost about the same amount of energy to convert between gas and liquid. Hydrogen atoms are so small they can permeate through plastic and metal, so all of the rubber hose and plastic containers are probably venting hydrogen into the room. Hydrogen storage is a huge engineering challenge, and just having hydrogen sitting in your tank, it will eventually leak through the walls of the tank. That's why automotive companies are trying to design sophisticated hydrogen fuel cells, and ways of chemically bonding to the hydrogen to stop it from leaking.
Steve: I'm sure a lot has changed in 2 years. but I have a suggestion based on what I have been seeing. You can only pull a partial vacuum on the tank the way you are doing it but your main goal is to Pull all the oxygen. Hydrogen is lighter than Oxigen. When pulling the vacuum turn the tank upside down. residual air/oxygen will sink to the bottom and be pulled out first. Residual hydrogen should be the only gas left. Upside down for vacuum and filling. Turn right-side up when drawing off Hydrogen to compress into a smaller tank.
Hey, great videos! But hydrogen is lighter than all the other gasses, why didnt you just empty the tank of all the non hydrogen gasses upside down? That way the last thing to come out is hydrogen
@ 2:50 I would be purging that line from your gauge to the ball valve with hydrogen. That line is full of air, If you were to add a T between the existing ball valve and add another ball valve and a vent it downwards you could purge most of the air from the line and any in the T as well since the hydrogen is lighter than air. I love what your doing, and your doing a great job. Not intending to Monday morning quarterback, but if you blow yourself up, who am I gonna learn from? Only other thought is to ground bond EVERYTHING that you can. One bit of static can flat ruin your day. Percentages are getting better! ETA not sure why you are no longer making vids on this. It has been a great bit of knowledge that you have been sharing. But thanks for what you have shared.
G'day Steve... been following for a while and waiting for new videos on hydrogen production/ storage. Have you got anywhere with the vac pump and compression...?? I wonder if a spark free gas recovery unit would do the trick as it vacs and compresses...??
Would flushing the storage tanks with nitrogen or other inert gas help with safety? What if you flipped the tank upside down after filling/before testing? I'm not sure if gases work like this but maybe it would promote the removal of impurities since the hydrogen would rise to the top of the tank while everything else sat at the bottom closest to the valve. I'd imagine it would give you a lower initial purity result but might make it easier to get it above 97% since you wouldn't have to pull a vacuum and recompress so many times
On that same note, why was it so contaminated with the valve being on TOP (tank right side up)? Obviously there is a lot of mixing of the gases despite density differences then. That makes me worried of the concentration of the hydrogen closer to the bottom of the bank. I deal with cryogenic liquids and I was thinking it would be neat to add nitrogen to the tank to build up some pressure, then immerse the whole tank in liquid nitrogen, turn it upside down, and open the valve to expel the liquid oxygen from it. Then, do hydrogen / vacuum cycles like in the video to build up the purity. But at least then you know that the contaminant is only nitrogen and not oxygen. HOWEVER, that tank is HUGE!
Maybe just get a hvac vacuum pump and pump air out of tank before us? Also you need to wait few hours before all water evaporates into the vacuum and then make vacuum again. Yellow Jacket vacuum gauges are good to check if you have vacuum in the tank.
Why don't you have 2 valve tank, and you fill it with distilled water and using the H2 gas to pump out the water, that way you will have 100% H2 remaining in the tank before compressing it.
Hi. I am wondering why you would need to run the Hydrogen through a separator when you are producing 99.95% Hydrogen directly from the unit? If you are going for 100% purity, wouldn't a heater connected to the units output eliminate the 0.05% oxygen residue?
Very impressive build!!! What is the duty cycle for the hydrogen electrolyzers and power supply? I'd be inclined to build a system that could refill a tank to a prescribed pressure, shut of the power supply, close a valve separating the generators from the tank, and activate a compressor to compress that into another tank at a higher pressure. Ultimately having a shutoff for the entire system when that tank achieves a target pressure. I would think if you could maintain a sealed system as above mentioned, and adequately purge your tanks, you should be able to achieve and maintain 99.9% purity quite easily.
when you empty the tank if you turned it upside down and let it set for over nite then bleed off the un pure air that is heavy air would that help purify the Hydrogen in the tank
@@Hydrogen4Health I recently got an inch to build one for a generator. Was really interested in the storage process and how long a tank lasts with the degradation that comes with hydrogen storage
Shouldn't you test purity with the tank valve being at the bottom? Tank upside down! That way any oxygen has had a chance to settle to the "bottom" where you have the valve
Hi sir, I am making a 100 plate dry cell and want to ask you should I use 2 water inlet on one side only water inlet for cell. I am using 6"*5" plates 100 plates and 2 gas output port. Please help
@@Hydrogen4Health but sir the problem is that the dc current start traveling from one side of the cell to another side by the water pipe!! 😥 Which cause access heat and low productivity. Current doesn't pass through the plates directly. I am using alternative holes for water displacement. After 15 plates I change holes direction
You should buy a huge high pressure gas cylinder and buy a high pressure compressor. The compressor cost about 400$ on eBay or China and can compress gas up to like 4000psi or a bit more, not sure... that will make your whole set up even more awesome. Screw Airgas company
@@Hydrogen4Health Seperators are easy enough. Your flow rate is so small you could do a number of stages. Even a Dehydrator stage would sop up any vapors I would think.
Can you try to build a container with a spark plug that would be burning off all oxygen content in the flow from the elektrolyzer? The oxygen content in the flow from elektrolyzer is very low so it should produce just a tiny flame when itwould combust and the container will not break or crack during combustion. If this stage would work properly you should be getting 100% pure hydrogen. I would be grateful if you would reply what you think about this idea.
@@protheon always try new ideas on small and safe samples. I might try it myself at some point in the future... Why do you think that this trick would not work?
@@protheon tead the post properly. Pure oxygen or pure hydrogen will not burn in pure composition. They have to mix. Pure hydrogen will not burn in vacuum, same as pure oxygen. You have to mix them togeather
@@Hydrogen4Health perhaps if you teach it as leaning purposes only, do not try this at home as it's extremely dangerous etc. Etc you can avoid liability issues. TNT does a lot of dangerous things and qualifies them.
If dissolves HHO in atmosferic air (78% nitrogen) the chemical bonds makes the misture suport compression, than you dont needs pure Hydrogen. But the mix nust be maked with small atomized portions of gas.

Jay Andrew why not just use the hydrogen as you produce it? No worries of it exploding or storing it!
Thanks Steve for all your hard work !!!
Trying to give out good safety
This is the ideal setup.
Even after drying the Hydrogen you'll want to final-filter the gas before chugging it into storage. Impressive!
You seem to have most of it sorted out quite well but what I’m concerned with is you must bear in mind the weight of oxygen and hydrogen therefore you can clear your system of oxygen far better
@Steve - Appreciate the video. We do vacuum distillation, and you can pull down that big tank in less then a few minutes no problem with a cheap little 4 CFM vacuum from ebay, for under $100.
Turn the tank upside down to purge the heavy gasses after you first fill to 20 psi. It will get your purity up quicker
agreed on the upside down could also add a purge valve plus include a DIY liquid nitrogen system to cool the hydrogen before storage

You can use an ammonia scrubber to eliminate that issue. Marble chips are a primary ingredient in an ammonia scrubber
it would be much easier to have a 2 valve set up similar to when pulling a vacuum on an AC unit before charging with Freon

Have you seen the pneaumatic and hydraulic boosters? Easily take your output from electrolyzer and get it up to and well beyond 7000psi
No, what are they?

Nice setup but why do you not flush with hidrogen your hoses connected to the tank , you would get even lower oxygen contamination in the tank.
I'm impressed by you
You should not only vacume the tank but you should also be flushing the tank with an inert gas like co2
G'day Steve... been following for a while and waiting for new videos on hydrogen production/ storage. Have you got anywhere with the vac pump and compression...??
I wonder if a spark free gas recovery unit would do the trick as it vacs and compresses...??
Turn the tank upside down and drain it...

So why not take this system a step further and use it for electricity?? Super interested in the technology for our dinner cruise boat!
Thx my friend, please, how much is the safe pressure of pure hydrogen that I can reach without warning
Pressure level boom
Tip the tank upside down. It will force the heavy gasses out the bottom.
Smart!
Maybe just get a hvac vacuum pump and pump air out of tank before us? Also you need to wait few hours before all water evaporates into the vacuum and then make vacuum again. Yellow Jacket vacuum gauges are good to check if you have vacuum in the tank.
Just about to say that

Is there a reason you don’t purge w something like argon. I know probably expensive...but better you and your garage are still here

this powersupply is fucking loud. it sounds like an airplane.
Awesome future tech.. What about PEM generators? How much they cost?
I need an update... we're the steaks medium rare?
you are using a refrigerator compressor to pump the h2 into that propane tank??
keep up the great work
Nice way and clear one.
Where is pt. 9 compressing into smaller tank
Did you ever get this pressed up to final target pressure of ~125 psi?
Still want to know what exactly you vdo with the hydrogen?? Oxygen seems way more valuable in a sense
Welding or you can use it to regenerate electricity using a hydrogen fuel cell.
Very impressive build!!!

I would think if you could maintain a sealed system as above mentioned, and adequately purge your tanks, you should be able to achieve and maintain 99.9% purity quite easily.
If the duty cycle of the power supply and electrolyzers are sufficient, you could even build a valve system to operate two buffer tanks.
Will you ever try using a fuel cell with this system? I see that tank of H2 as a big battery.
I would love to but too expensive for me right now.
at 1:32 you connected a hose full of air, which later went in your tank.
If that tank is not Vacuum rated, I would not recommend complete evacuation, it may crush like a beer can.
Nice
where's part 9?
Is this a standard gas tank? I thought Hydrogen cannof be stored in a regular gas tank.
pure hydrogen can
And you are right. It will leak eventually
Heat bottle empty ,more vacume when cool.
Hi can you recommend some compressor for hydrogen to compress it to 30 BAR? I want storage hydrogen in metal hydride tank?
when you empty the tank if you turned it upside down and let it set for over nite then bleed off the un pure air that is heavy air would that help purify the Hydrogen in the tank

Did you ever bump up the voltage to 24 volts? Your website says 5 volts max per converter. 24 would be 6 volts each.
Found out it's best to use a separate power supply for each generator. 5v power supply works the best.
