DU: Beware the Hydrogen Economy Lies being pushed by the Fossil Fuel industry.

[longship]

11. First, hydrogen is not an energy source.

There are no natural sources for molecular hydrogen on Earth. NONE!! All hydrogen comes from (electro-)chemical processes. All of it.

Second, is a rather significant issue of the laws of thermodynamics, which I believe physicist Arthur Eddington once wrote about.

Aha! Here it is:

The law that entropy always increases, holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.

If you want a hydrogen economy you are going to have to put more energy into generating the hydrogen than you will get out of burning it (in whatever way you do that).

Hydrogen could be useful for things like jet planes, rockets to outer space, etc. But a hydrogen economy must be built upon an already existing green energy economy or it is utterly useless.

Hydrogen is not an energy source on Earth because there is zero molecular hydrogen on Earth.

Physics 101!

R&K my friend.
