When I used to work at 3M Central Research, our building was plumbed with
nitrogen. It all came from the evaporation of a huge liquid-nitrogen tank
in the corner of the building. If you wanted dry nitrogen gas, you just
opened the tap in your lab. If you wanted liquid, you would take a dewar to
the big tank and fill it.
I don't know what it costs to get a tank of liquid, but I seems to me that
it would be pretty spendy to use for air tools.
Keeping the compressor and power station separate ought to keep your
electric power cleaner. Still and all, this seems like a lot of stuff to
cart around. Maybe you need Pat Washburn to make you a pit cart with all
this junk built in.
