Water H2O convert to Hydrogen peroxide H2O2

SUMMARY

The discussion centers on the conversion of water (H2O) to hydrogen peroxide (H2O2) and its potential use as a fuel. Participants highlight that while hydrogen peroxide can be produced through methods like electrolysis and UV light exposure, the energy required for its synthesis often exceeds the energy gained from its combustion. Alternatives such as hydrogen fuel cells are recommended for reducing petroleum dependency, as they utilize electrolysis to produce hydrogen efficiently. The feasibility of using hydrogen peroxide as a fuel is questioned due to safety concerns and inefficiencies in energy recovery.

I know someone who had about 15 years ago a small factory producing hydrogen peroxide, I think they were using peroxodisulfate method. If they could manage it, it must be relatively simple. But - sorry - I am not going to ask about details.

Fact is you people seem to be missing the point. It may be about energy on demand.

It does not matter what the efficiencies are or where the power comes from but that H2O2 is a concentrated form of energy and that this energy can be very effectively released on demand. And that storage is usually not a problem.

He/She who said burning H2O2 produces pollution is nuts: H2O2 + silver = H20 + 0 + heat! - It's clean
fuel cells are not!

Also when it comes to efficiencies take note that enough energy passes over every square meter of land (on average) to power up an entire household BUT converting it to something useful, and to be available at the right time is the catch!

There are a number of methods available to produce H2O2 - chemical (industrial) and electrical (hobby (: )

Then there are a number of methods available to concentrate the mixture (scientific, industrial, hobby) p.s. try freezing it, H2O and H2O2 freeze at different temperatures. Otherwise if you can afford it the Brazilian made stills are the best high grade concentrators.

Some nut job in New Zeeland has figured out a car battery sized gadget that does the conversion as well. - no details.

P.S. H2O2 is dangerous - reacts like acid to the skin. Keep it in a cool place, Must be able to breath. If you want to make a bomb just put some in a sealed container and place it out in the direct sun (heat increases the decomposition and that releases more heat = bomb)

H2O2 is the answer to depleted fossil fuels. and currently the Chinese can produce it at 1/3 the cost of Petrol.

I research this topic several years ago and the closest that I got was a process similar to electrolesis,

In that you had a tank of water, and positive and negative electrodes, in the water, but what put me off was the use of specialized materials such as platinum... I do remember that while this system did produce H2 and O2 at the electrodes it also produced H2O2 between the electrodes. There was also a pipe feeding O2 in between the two electrodes. The trick was knowing exactly where the H2O2 was forming and to siphon the H2O2 out of the tank directly at that point. I never did find "that point"

how to detect H2O2? - another interesting topic.
