And when you consider the heat of compression is still in the cycle of a gas turbine you see the problem with using compressed gas. The refrigeration at expansion has to be input from the environment or you see a loss on both ends.

Hi Jeromie,
Do your have more info on this, I love the idea. Maybe a good web link.
Would a system like this be hard to set up? and materials / separator?
The reason I ask is that my family and I will be moving to an eco-village
next year. We are required to put in one alternative form of energy

that could run a home.

Hi all
You don't need to compress the hydrogen, there are electrolisers which work
a 200 bar (3000 psi, yes threethousand psi) and are being used in the UK
to produce hydrogen from excess wind genaration and feed it through a fuel cell
in calm periods, to produce electricity.

Yes I have also heard of using a wind turbine to turn an air compressor
and store energy in compressed air. I don't know about the efficiency
though.

I really like the idea of flywheels as opposed to batteries for wind/solar storage, I'm suprised no one has mentioned them yet.

The storage of energy by lifting water has a long and successful
history. I think it's common for hydropower companies to use excess or
off-peak power to push water up into the reservoir, increasing head
pressure for peak demands. Hmmm... kinda stinks of perpetual motion eh?
Windmills have
Take a look at CaO
It is made by heating CaCO3
In sailing ship days fires were started when barrels of CaO got wet.

The other thread [Solar panals or wind] is discussing the viability of an air car and made me wonder of excess wind energy can be stored as compressed air.

Compressing air has an enormous loss due to heating. THe heat is soon lost and the attendant energy with it. If you could compress it without raising its temperature then it would resemble water energy stored in a reservoir on a hill.

Jim,
Lead-acid batteries 80% efficiency (real) and I think that other
types have a slightly better efficiency. This is however not the main
point for them, life and maintenance are.
