That isn't hydrogen peroxide production and of the six methods mentioned in that
article for producing hydrogen alone, only the photobiological one is "free" in
the sense that it doesn't need an external artificial power source to work
(sunlight is considered free). The production of hydrogen peroxide would only
add to that because it is a multi-step process that consumes alot of external
artificial power to work.

But is one hell of a lot more efficient than burning petroleum products and
fossil fuels!

Exactly how much more efficient is it? 10%? 20% How much?

And how about production? How much land or water area is required just to
produce one gallon of this stuff? Let's compare that to petroleum.

What about this don't you understand?

Background /Common uses: Free hydrogen is found only in very small traces in
the atmosphere, but solar and stellar spectra show that it is abundant in
the sun and other stars, and is, in fact, the most common element in the
universe. Hydrogen is already used to produce countless products and to
enhance many industrial processes. The U.S. produces 100 billion cubic feet
per year of hydrogen for industry and for the space program. The largest
user of hydrogen is the petroleum industry for converting crude oil into
gasoline and hundreds of chemicals. Sometimes used in welding torches for
welding or cutting metals.

What you are ignoring or not understanding is that it takes energy to
produce and accumulate hydrogen, or hydrogen peroxide. Just because
it makes up most of the universe doesn't mean you get it without
effort.

It takes *energy* to do it. The potential advantage of such uses is
that the energy needed to produce your hydrogen and oxygen, or
hydrogen peroxide, can be produced in centralized, efficient plants
with pollution controls. That has the potential, at least in
principal, to shift emissions from millions of car tailpipes to a few
thousand power plants. Of course, most of these plants still burn
oil, coal, or natural gas.

It's not "free energy". Not by any stretch of the imagination.
