But ZF, hydrogen is still a half-baked energy storage medium, no? You would be better off compressing air with the energy it takes to make hydrogen. I mean folks throw the term "renewable hydrogen" around, but the typical plan is a very inefficient use of electricity.
And, speaking of x-prize, ZF, how is making Carbamide from natural gas "zero fuel" anyway? It is an interesting way to carry energy, I will give you that much, but the hard part in making it "renewable" is left undone for the x-prize competition AFAICT.
i.e. How do you plan on separating the N from the O coming out of the industrial plant?
and How do you plan to make "renewable hydrogen"?
I do think it is a very interesting and unique approach, but would like to see how efficiently it compares to, say, LiFeP04 storage of "renewable" energy.
ob chicken: I wonder if I put a steam boiler on my rocket stove and started cramming feathers in there if it would burn anywhere near clean and make my bike move?
