Thermodynamics_Solar Hydrogen vs. Central Electricity Generation

Centralized Electricity fired by fossil fuel, two thirds of the energy
lost
up the stack, more lost in transmission, Ten Percent buffer for surge
protection, which averages out to less than twenty percent fuel efficiency
at the end user site before use_ fossil fuel to electricity back to heat
with all the losses and inefficiencies?

Solar Hydrogen uses the sun, converts to electricity, to Hydrogen. The
cogen
gives the sun more efficiency than the fossil fuel in conventional power
plant and it is free. It is collected with facilities way less capital
intensive than any fossil fuel power or nuclear plants. The tens of
thousands of square miles destroyed by fossil fuel leases and coal mining
is
a moot point when the land use is concerned.

With the modular strategies using Concentrator solar collectors the heat
can
be used directly rather than conversion for many uses. If the Solar
Concentrator electricity is converted to Hydrogen the hydrogen can be used
directly as heat rather requiring very little electricity re-conversions
and
the original conversion medium is free energy from the sun. Hydrogen in
the
existing natural gas grid as H85 is less fragile than electric
transmission
lines in extreme weather.

When we incorporate sewer gas, dump gas, mine gas, other natural gas and
methane producing sources
we have the beginnings of a back to town gas that is still being used in
Europe.
We can add the Solar Hydrogen as we gear up the production and use all the
compatible
gases which would pollute without benefit if left to vent to the
atmosphere.

Your efficiency numbers are way off of the mark, but even if they were
correct which they are not, it's not about efficiency at least thermal
efficiency. It's about economic efficiency; i.e. dollars per installed kW of
capacity and operating efficiency, dollars per kWh generated. In otherwords
it's ALL about MONEY and hydrogen is NOT cost effective no matter how you
slice it. Today there is no such thing as "Solar Hydrogen" at any cost. If
you run the numbers, you will see why.
