Na + H2O2 (50%) -> H2?

[David Harper]

Hi Dave,
I'll concede. In the light of the information you have provided, my
original comment should be considered wrong.

But at the least, they had a science to grind on.

You're correct. It wasn't all unknowns. There was some science for
them to build on.

What I don't see is a
hydrogen science with mysteries to solve. And I've been all over the
hydrogen thing. So, at least without new information, I don't believe
hydrogen can be made part of an energy solution. There may be some kind
of material science breakthrough to conquer the storage problem, but
that just a rather small 'if' from here.

You do make many good points. Hydrogen isn't a viable option right
now, nor will it be unless certain tech advances allow it to become
practical. Like I said before, If I were a betting man, I'd place my
money on something else other than a hydrogen.

Thanks, Dan.

Dave

When the coal is used as the only energy source, it makes no dif (ignoring
some possible differences in efficiency)whether you produce H2 only or HxCx,
you still use all the energy that was in the carbon. It is probably a better
process from a CO2 perspective, to produce hydrogen from some alternative
source, then use all the carbon in making a fuel oil, but in that case, you
would not want to use the coal at all to make hydrogen. This would, of
course, "waste" all the carbon in the coal, eh?

Anyone else seen the recent research about the PSII (photosynthesis
II) protein. I would assume that mass production of this protein, or a
simpler version tailored to our needs, could begin within the next
decade. This would provide the most fuel efficient set up I can think
of. You could have water stored in a tank (that's easy) and have a
panel on the roof of the car similar to a solar panel filled with the
protein and run water through it to get hydrogen. However the storage
of the separated components is still an issue.

Can anyone provide more details about the above reaction? Is the Na
consumed? What are the other products?

Doing anything with concentrated hydrogen peroxide is fundamentally
insane.

Even the X-prize candidates are not allowed to use it.

I'm not sure that statement is accurate.

Armadillo Aerospace is a contender (soon not to be by tomorrow, if SS1
does well), and they use H2O2 propulsion.

Concentrated H2O2 is not child's play, but then again, neither is
ammonium perchlorate, H2, or nitrous oxide,

Last I heard, no supplier was willing to sell hydrogen peroxide to
X-prize candidates because of the liability.

Don't be absurd. H2O2 is just too way low an energy to mass ratio to be any
good except for some odd tasks like small positioning rockets where a lot of
short pulses may be needed (and you don't want to use something really nasty
like hydrazine), or like the steam rocket belt where you really don't want a
high energy fuel and a very hot flame. The stuff is a lot easier to handle
than LOX and LH2.
