@newsfe3-gui.ntli.net:

why not use the cooling water thats wasted in the power plants,
its already warmed up or even evaporated so should
require less energy to produce h2.

Colin =^.^=

It would need trasnported. Either the warm water or resultant H2,
which
itself takes energy.

you cant realy transport warm water very well as it gets cold,
and it would be pointless transporting both the water and the
electricity
from some place to some other place, then transporting the h2 to
somewhere
else too.

theres huges gas pipelines all over the place, presumably these will
eventually end up carrying h2 too when we think weve ruined the planet
enough or ran out of fosile fuels.

either way if the energy needed is renewable and available its not
then an issue.

I gues the hydrogen is easier to transport becuase it is lighter than
the
amont of water used to make it,
although its far more volumous.

if it becomes possible to viably convert h2 into a liquid fuel or a gas
eqv
to todays gas
then it requires little change in distribution.

Colin, Are you a degreed engineer? What university?

...Jim Thompson

I went to uni over 25 years ago here in the UK,
most of what I use has been learnt since then,
or I new as a hobby wich i startyed at 10yrs

I did software for most of my life anyway as
pay was 2x but i never resisted the opourtunity
to get involved in the electronics as I often wrote device drivers etc,
it always bemused the elec engineers when i told them exactly
what was wrong with their hardware and how to fix it lol.

rest of my family is entirly mech eng orientated
so I have a fairly wide range of skills

why do you ask ?

Colin =^.^=


Your misconceptions about piping H2, and what H2 can do to existing
pipes ;-)

I dont realy think I had any misconceptions about it at all,
I offered an idea for discussion.

I know H2 is rather awkard to use,
such as the weight of the storage is
unatractive for vehicle use.

thats why I also added IF it could be converted to an eqv gas
it wouldnt need any change in distribution.

I didnt know just how corrosive H2 was though.
If we run out of gas I gues the existing pipes would have to be
modified or lined before H2 is put through them
or maybe this isnt even an option ?

Ive heard about attempts to convert it to methane and
also to liquid fuels. it might take some energy
to convert but this might be offset by
needing less energy to handle it.

if we realy start to run out im sure this will
have more and more money thrown at it until it is solved.

H2 doesnt realy come into electronics engineeering a lot anyway,
and I never claim to be a chemist,
I consider my skills to be spread out over enough fields without being one
this is after all a
electronics forum, well err sometimes anyway.

it just seems such a no brainer to re-use the cooling water
if the amount needed is going to be a problem,
wich was my original post.
