Never considered the idea of generating hydrogen (rather than electricity)
with nuclear power and transporting it via pipeline.
Think the transport can really be made lossless (economically that is)? H2 is
much smaller than any hydrocarbon and would be more prone to diffuse through
the pipe and compound that held the pipe segments together. No idea if
diffusion would be a significant source of loss though. Also wouldn't the pipe
have to be significantly larger (or under much higher pressure) since the
energy per unit volume of hydrogen (at some pressure) significantly less that
natural gas?
