Not a problem as they just are designed to carry
it. Also in 5 or so years lithium batts should be
availiable.
Also H2 storage weigh about as much as lead batts.
They could recharge them from a wind gen or regen
from the prop while under sail.
There is a neat sail rig called a Plane Sail that
controls itself and doesn't have to be reefed in
storms that would be perfect for them. Lots of wind up
there. No H2 needed.

I'm amazed you would bring this up. There is no
such thing as free electricity. If you waste it it
costs for the plant size and whatever you could use it
for but didn't. Very bad design and what has given us
the problems we have now.
H2 loses 1 to 20% per day in transport, storage.
It leaks right thru several inches of steel!!! And
causes the steel, under 4,000psi to weaken, not good.
Best, most eff way is to ship it as electricity in
wires and store the energy behind a dam in Iceland.
Besides hydro they have a LOT of geothermal power
plant possibilities.

About 900 miles. The cable has been made and
probably laying it now. 1 conductor in the cable and
earth for the other. There's going to be some really
big ground rods ;-).

But why if batts are 2 to 3 times as eff. By then
Lithium batts should be reasonably priced.
Even ICE's running steady state can be more eff
than Fuel cells at 1/10 the cost or less.
With less than 1 million people I doubt they can
afford much research.
Maybe once the money comes in from selling the
electricity, fuels.

H2 and CO are known as syn gas and are basic
building blocks of many processes. C can come from
volcanic vents, garbage, fish parts, ect and even the
air.
Combine H2, CO, heat,pressure, catalyst(Ni) and
you get methane ( nat gas). Add O2 and you get
methanol. You already have the pure O2 from making H2.
Also several prototype plants now make a much
cleaner subsitute diesel, gasoline fuel from syn gas.
Some are the size of a car. It's a similar process to
the Coal- liquid fuel plants from WW2.
