Looking for information on domestic hydrolysers, H2 storage and gas
burners. [For when the sun doesn't shine and the wind doesn't blow and
its time to eat]

How would hydrogen help ?

You ARE aware of the problems with H2 storage right ? Like the porosity of
most (all ?) materials to the tiny H2 molecule giving rise to H2 losses
and potential accumulation of explosive vapour mixes, not to mention
hydrogen embrittlement of steel. Oh and then there's the pressure of the
storage tank to consider or the 'boil-off' losses if you go for liquid H2.
Oh AND the energy losses associated with either highly compressed or
cryogenic storage of H2.

It's 'lose, lose, lose' all the way !

Thermodynamic fundamentals GUARANTEE this ain't gonna happen.
Ever.

There's also the DOT orange book requirement to keep the hydrogen at

least 2600 feet away from any occupied structure.

Your problem is that you appear to be insane.
WTF has any of what I want got to do with "gasoline"?
It's about powering a home that is miles from any grid, either water,
gas, sewage or electric.
The location has an average all-through-the-year windspeed of 15mph ie
windpower is more than cost competitive with UK domestic electricity
prices.

And I should add that excess wind electricity generated will also be
dumped into the water heating system, esp in winter months.

Because no means of doing so is known that is not a huge gasoline

Yes Don, And since gasoline is now so damn expensive, we should destroy it!
We should destroy the whole concept of petroleum energy. In fact we should
quit using it all together and switch to biofuels, wind, solar geothermal,
nuclear, etc. with all possible haste. It's pure folly to remain on this
OPEC merry-go-round where we have no control and are subjected ever
increasing prices fueled by insane demand and greed. Petroleum is a finite
resource and it is suicide to continue our societies idiotic reliance on it.
Let's destroy all gasoline and move on!

BTW, please explain how the OP's hydrogen idea is a "net energy sink" from
his vantage point. If his wind turbine idles at night it produces no energy,
none, nada. If he make hydrogen he stores some energy. It makes no
difference what the efficiency is because he is comparing what he gets to
zero, nada, nothing. He is not comparing it to gasoline, the grid or U235
for that matter.

Even if wind electricity was the same price as grid, it would still be
outrageously too expensive to waste on electrolysis.

Instantly and irreversibly destroying most of its value makes no sense
whatsoever.

Install more batteries and use electric?

Stop talking bollocks and tell me the most cost effective way of cooking

Don, while I agree with most of your posts, in this case the
considerations may be different, although of no significance to most
of us.

Assuming that this guy evidently believes that he has a cost-free
energy source to produce his hydrogen, and if so inefficiency or
energy loss is not an issue for HIM. For most of us energy effiiciency
is in fact a major issue, and a vast majority of us harvesting energy
from nature cannot afford to waste it on the inefficient production of
hydrogen.

For those fortunate enough to have a fast moving stream on their
property, energy is easily available to capture and store over brief
intervals. For this purpose storage batteries and thermal heat
reserves in rock or solution are common methods. Conversion to
hydrogen isn't.

I would love to have a completely energy efficient home powered by
solar energy, but not surprisingly can't afford the price of
admission. I have no doubt that you could build a grand solar powered
home, if you have $1,500,000. to spend in addition to the usual
construction cost. Sadly, I don't have this amount of pocket change
available, but know someone who does.

Email Brainard Holmes, ex CEO of Raytheon, who owns such a home in
Lexington, MA, and sometimes takes tours through it. Treat him kindly
because, like me, he is an old and sensitive guy. Still, Brainard has
though his life's efforts achieved what many of us would wish to
achieve. Brainard has in the past posted extensively on some of the
environmental oriented newsgroups, and is truly a very nice and
dedicated person.so tread carefully when approaching. At last count,
he would love to give you a tour, because he is desirably proud of his
environmentally responsilble home (damn, only wish that I could afford
to build one).

Brainard, forgive me, but your lamp is so very bright that it is
difficult to hide under a basket. You likely don't remember me from
some years back, but I remember you.

Use a natural gas kitchen oven. Compared to electrical heating, this
saves about 50% of the energy cost. Natural gas in cheap in comparison
to electricity, because what do you think it is that they use to
produce electricity? Yes, natural gas and coal, unless you are
fortunate enough to have a nuclear plant in your local.

So letting the wind generator idle at night and shipping in propane is
going to be cheaper somehow? Why's that?
