That is why town gas contained water and drain points had to be fitted in
gas runs in homes.  Some would freeze in winter.

 I doubt most of us want to drag trailers full of uncompressed hydrogen
around just to get to the corner store and back. Hydrogen contains very
little convertible energy per volume size.

Come on, folks.  The detractors are saying that Nocera has claimed to
invent electrolysis. The evangelists are saying that this is the solar
breakthrough we've been looking for.

Neither of these are the case. Nocera is only claiming to have
developed a catalyst for the oxygen electrode that provides excellent
(he's claiming nearly 100%) efficiency without the use of toxic
materials or a pressurized vessel.

That's all.

It's a step in the right direction.

No, it doesn't have much to do with PV, other than as a potential high-
efficiency energy storage mechanism.  You're still stuck with the low
efficiency of conversion from solar flux to electricity.  And it's
almost certainly going to be more expensive than lead-acid batteries
-- but this solution (pardon the pun) probably scales up better.

Stop pooh-poohing or bowing and scraping.  Neither are warranted.
It's just another technology development that MAY be applicable to the
problem.

Personally, I'm hoping for someone to come up with a high efficiency
photo-electrolysis solution. Go directly to H2 and O2, and then always
generate your power from a fuel cell.  THAT would be the big
breakthrough.  (Well, that and an inexpensive, durable, high capacity
fuel cell.  And safe, high capacity H2 storage.

I would have been more impressed with
