What are the industrial application of mass produced hydrogen and oxygen? |
Assume if somebody invents a magic catalyst which help reduce the cost of
breaking down water
into H2 and O2 by 50%. Where are the currently tappable destination for
these two gases? How
does the hydrogen plant seperate the two gases?
Thanks.

There was an interesting article in one of the science mags last year. It
discussed what we should use Hydrogen for _first_ if it suddenly became
cheap and easily available. I recall they said we should use it to for heat
and power in our houses NOT in our cars. I think they reached this
conclusion after looking at the total impact each source of energy has on
the environment after all factors are considered.

Electrolysis will separate the elements from the molecule.
By placing electrodes in the water, gas bubbles form at the
electrodes and will rise to the surface, where they can be collected.
The catalyst is sodium chloride (common table salt).
It will not reduce the cost, the energy out is equal to the energy in.

Sodium Chloride is _not_ a catalyst in this case. Electrolysis isn't
influenced by any catalysts at all[0]. What the salt does is provide free
electrons, making the solution conductive. This is a very poor choice of
electrolyte for routine electrolysis, because the sodium and the chlorine
come out of solution at the electrodes, and create a terrible mess.
Use H2SO4 if you need to make your water conductive. (one drop of
battery acid will make 55 gallons of water conductive enough to
electrolyze.)
And, unless you really have figured out how to do real magic, you will
_never, ever, ever_ get as much energy back as you put in.
Cheers!

So, use platinum plates.

A better catalyst.

Too true, but "Sea Squid" wanted "a magic catalyst" which helps "reduce
the cost" of breaking down water into H2 and O2 by 50%, which betrays a
teenage underlying lack of knowledge of economics, chemistry and
physics, so it seemed appropriate that he could conduct a safe
experiment in his mother's kitchen using some AA cells without spilling
battery acid
on the floor or work surfaces, and his question was how to collect the
gas. I gave him the same answer I'd give to my own grandson.
Cheers!

Have a nice day, Rich. It's his mother that will be coming after YOU
when her wedding band is sawn in two and the place stinks from a
mix of H2SO4 and oven cleaner instead of some spilled salty water.

Oxygen is used in hospitals, chemical processes, and spacecraft.
Hydrogen is used in chemical process, spacecraft, and horribly expensive
alternative fuel vehicles.
How

They strip hydrogen from hydrocarbons. A whole lot cheaper than breaking
down water.

There is also a gang in Canada who claim to be working on a method of
dissociating water using solar energy to drive a catalytic process,
but we have not heard much from them for a while.

And when we do see it, it's rarely more than about 30 degrees
above the horizon.
Catalytic process be damned. The problem with dissociating
water to get H2 and O2 is simply the energy you have to put
into the stupid thing. If we had the energy available to make
scads of H2 out of water, we'd not have problems with energy.

This actually took/takes place here in Tempe Arridzona. But we have still
had phenomenal amounts of cloud cover and rain.
The link worked. For long links, I have had good success adding the
following:
<

all together, and not on separate lines (I did this so that Outlook didn't
munge it all). This seems to make Outlook behave a little more friendly

It occurs at elevated temperature, and they "trap" the oxygen. Not quite a
plasma, but even at room temperature water dissociates just the tiniest bit
(pH). I'll just be sad to see all the hydrogen spills being cleaned up...
sky mops are hard to handle. ;>)

1) It must work.
2) It must generate a profit as it works.
3) It must work generating a profit for 20 years.
4) Ain't no such, even on paper.
BTW, building your physical plant in a nice flat arroyo seco is an
empirically bad idea when the vagaries of weather deliver an arroyo
mojado. California is enjoying the wettest year since 1883-4, thereby
confirming the devastating heat and desiccation brought forth by the
Greenhouse Effect and Global Warming. It's bloody cold, too. It will
be great year for wildflowers and blooming cactus in the deserts.
We're hoping everything in the dry land ecology drowns, opening the
areas for development.

Sometimes an arroyo can flood in an instant from a storm so far away you

The consensus is that there should be an interesting fire season this year,

Agreed. If it were 100% efficient, or even 60+% efficient, wouldn't it
still be a preferable method of storing energy? Batteries are not terribly
efficient, and capacitors have similar issues (either very large, or just
batteries in disguise).

How
does the hydrogen plant seperate the two gases?
Thanks.
By supplying energy to dissociate water. Actually, the best technology
for electrolysis turns out to be nuclear power plants. Europe has a
much higher fraction of energy supplied by nuclear power than does the
US, and China is on a path to quickly surpass the US in capacity, as
well. Despite Chernobyl and 3-Mile Island, nuclear power plants are
beginning to re-emerge in power planning in the US.
A catalyst that reduced the energy threshold by 50% AND could produce
in quantity AND did not cost more than the energy cost saved, would be
a boon worth tens of billions of dollars.
