19. When I think of industrial processes ...

just off the top of my head I think of heat, heat transfer, and motion. Those things are now pretty well handled at the least cost by fossil fuels making heat and electricity. Yes, both of them could be done using H2 in the process, but at added cost and complexity, so why bother if not mandated by some law?

I don't know much about chemical processes that use pure hydrogen as an input, but I suspect there must be some. Currently hydrogen is most cheaply made by reforming natural gas. You can make it from electrolysis, but why bother if it is less efficient and more expensive? Again, unless there is some law forcing it.

At some price of natural gas electrolysis will be competitive with steam reforming, but I don't know what point that is. And still, nat gas will always be easier to transport than H2. which affects price in different places.

I don't know, just stream of consciousness on my part.

I am interested in the prospect of using hydrogen for industrial manufacturing StevieM Jun 2014 #13
I really have a hard time seeing how this wins over regular EVs caraher Jun 2014 #14
But what about using hydrogen for other purposes? StevieM Jun 2014 #15
I can certainly imagine other uses caraher Jun 2014 #16
What do you mean by industry and manufacturing? oldhippie Jun 2014 #17
I'm not totally certain myself, which is why I was asking. I think the best examples StevieM Jun 2014 #18
