tvoivozhd---there would certainly be hydrogen leakage, and as reported 
last year, 10-15% damage to ozone layer likely.  A possibility of it 
being sequestered in soil, but no definitive study on the matter.  There 
is sufficient time for study however---in the past it took fifty years 
to switch from one fuel to another.  I see no reason why hydrogen would 
be an exception

Denmark took over fifteen years to drop fossil fuel dependence to 2%, 
utilizing a mini Manhatten Project crash program.
With the oil superbribees in charge here, we will see no Energy 
Manhattan Project crash program in the U.S., regardless of consequences.
