Preference for CH4 Pipelines, Ships (fossil or not)
If a Methane pipeline has a leak - its flows "UP" into
the Air - not into the ground. It may even catch on
fire and burn explosively. BUT, when all is over, no
real local environmental damage is done.
Same goes for shipping in sensitive coastal areas
(such as the Georgia Strait, BC)
Once the fire is out, you only repair human construct.
