Well we dont use natural gas to move things around I suppose is the point. My last foray into this was almost a decade ago, but when I did the work, I know that the physical movement of things (in the case I was working on it was jet fuel from oilseeds) was a very significant factor in the overall analysis. The moving of thing A from location X to location Y to convert it into product B, then to move product B to location Z to convert into product C ended up being more than enough to flip the whole thing over. I think the next biggest factor was the grid mix for the conversion steps. I think another conclusion was that if we could do it all on-site, it did pan out. If farmers could use marginal land, didn't have to move the seed offsite, and had the additional equipment to convert from oil -> bio-diesel, it might make sense for some growers. All of that understanding may well be obsolete now. TLDR: Moving heavy stuff around burns a lot of fuel. If you have to move things from place to place, its just not worth it.
