Energy for free - solar farm at sea

[Dave]

Not free energy, but renewable energy you don't need to pay for the
land, because it is on the high seas. i.e. no licences or fees, just
pirates and whales to look out for.

Basically a general purpose freighter with about 100 containers ready
for liquid hydrogen (cryogenic). Anyway from the freighter, the crew
deploys inflatable self steering barges with lightweighted solar panels
about 100mx40m big. Nothing on these should be particularly toxic.
After deployment, a man with a bandana on his head and a curly earring
in his left ear goes along and plugs them together.

They are all connected electrically to the ship. So far so good and the
electrolysis begins. Then if it gets rough they unplug themselves and
with the smart steering capability get back to the mothership general
location. Too rough, and then the smarter architects need to work out
the risk of losing non-toxic kit against the costs of robustification,
or bringing them all in, and lost production.

Nor sure how easy it is to transfer the filed containers of hydrogen
back to the port, or if you can transfer them to another ship at sea.
If not, you would sail back, and maybe another takes its place.

With like 1.2GW of generation should get a good return on investment at
current price of green hydrogen, if development is subsidised.

This is an active area of research:

No, it is not, it is a report on how badly seawater and salt spray screw
up solar panels on ships and has nothing to do with pie in the sky solar
farms at sea.

Only if you are more than 200 nautical miles out.

So where is the big liquidation plant needed to liquify the hydrogen and
where does the 3.3 kWh/kg of energy needed to do it come from?

Why would these barges leave the area of the mothership for any reason
other than transport?

Leaving the area of the mothership conflicts with the concept of
everything being connected electrically.

Yep, you really have this all thought out, don't you?

Everything gets a good return on investment if subsidised enough, which
is how a German company made lots of money selling solar power at night
that came from rented diesel generators, until someone noticed the at
night part.

Yet another childish pipe dream with no understanding of the physics,
logistics, legality's or finances involved.
