the nitrogen oxides are a huge problem, so the O2 must be saved and reused.

H2 storage is a huge problem, there are small tanks for cars and some 
refueling stations, but not for large factories from what I can tell.

If you liquify it, how much more energy does that take ?

and if you have 100,000 of liquid H2 in a large underground tank, in 
downtown Anaheim could that be a safety hazard?  would people think it 
is a safety hazard ?

(just pump the water uphill)
