Depends on the efficiency of the production process. I doubt that any gasifier reaches the levels of efficiency they quote (though those are likely to go down as the process is scaled up).
"Hydrogen in general is produced where it is used."
Gee, you need to tell Air Products that, they might want to switch from the thousands of cylinders of hydrogen they ship out on a daily basis. In METAL TANKS, no less. Gosh, I wonder why those tanks haven't "gone all brittle" and "lost their hydrogen", since the problems with hydrogen storage are so severe. Excuse the sarcasm, but I get really tired of seeing that bullshit trotted out on every thread about hydrogen. I'll say this one more time---at room temperature, these things are NOT A SIGNIFICANT PROBLEM. At elevated temps, yes, but at ambient temps, the rates are so low that any significant effect would take decades, if not centuries, to show up.
Bottled hydrogen in a very small part of the hydrogen market.
There is not enough energy in a bottle of hydrogen to be feasable for fuel use.
The hydrogen bottles are designed for hydrogen. Black pipe infrastructure is not.
Hydrogen has many disadvantages and only one advantage. If you believe that man made CO2 is causing global warming then hydrogen allows you to move the CO2 production from the tail pipe to a plant where you can capture it.
Your sarcasm was noted and ignored.
