Hi Guys. . .

I have a hydrogen powered bicycle, and now I want to create my own
Hydrogen from home.

1. I live in Australia with plenty of sun and plenty of water.

2. I do not want to use batteries, or recharge an electric powered

3. I have loads of money.

So, now I want to build a solar powered hydrogen production plant for
home. I can build cells easily, not really rocket science (or I
suppose it really is). . .


a) Can Hydrogen be easily stored in aluminium tanks ? I can weld these

b) What would be the most effective achieveable solar ampage/voltage
for creating the days hyrogen for the next day's use?

Replace it with lithium batteries

Lithium batteries can be charged by any DC outlet

Even with plenty of sun,
You need for the same only 1/3 of power charging lithium batteries
instead of hydrogen

Typical case of brain washed by the hydrogen nonsens

That's really necessary for an exotic hobby

Look, while I agree that most of the hydrogen stuff is extremely
premature hype, why not take the fellow at his word and suggest
solutions instead of throwing rotten tomatoes?

So what if using hydrogen to power a bike isn't "sensible".  You can
still learn something from it.

Hey, my grid-connected, battery-backed PV installation isn't exactly
"sensible" either. It's been running for 7 years, and it might yet
break even in another couple of years -- which is silly from a
financial point of view.  The only real need it supplied is the
provision of energy regardless of brownouts and rolling blackouts, and
that could have been taken care of by installing a whole-house UPS for
a lot less money.  But I still wanted to have the PV system because
it's fun and interesting, and I might learn something from it.

Give this guy a break!

Me, I don't know much about solar hydrogen production or efficient
storage. It sounds like a research project to me. There are
straightforward, brute force, inefficient solutions that might get you
started (electrolysis, compressors, aluminum tanks).  Presumably there
are better options.  I've always assumed that direct solar hydrolysis
will eventually be the way to go, but I don't know how you get there.

Lead batteries have been the death for many
electric car projects.

Lead batteries are far to expensive for their performance

Imagine lithium batteries with 20 years, 30.000 full cycles
for 300.-EUR per kWh.

This will even outperform pump storage power plants.

Every grid connecte house a
solar power plant and a
storage power plant

I just study the theme, the data are from the most advanced
lithium battery resarch company.

In some days, I will give a link to the caculations based
on the basic data from the new lithium batteries.
