1) In the earliest days of fracking in remote North Dakota there were no pipelines in place to carry the crude so it got trucked to rail centers, loaded on tank rail cars and sent to refineries. Several of those rail cars blew up. The crude was not chemically what the cars were designed for (conventional, non fracked crude is not identical to fracked crude). This got addressed with rail car upgrades. So explosions CAN happen.
2) Any time you cryo cool natgas you start to get loss. Storage is never perfect. It boils off and disappears into the atmosphere. This is a significant reason why LNG ships carrying nat gas cannot price like piped gas. The ship’s fuel cost and the lost product enroute. This will be no different with rail cars. We should not be knee jerking support for LNG rail transport. It is not admirable.
3) Yes the envirowhackos will oppose anything at all. But no, this is not the hill to die on because LNG transport sucks. Gas transport is pretty damn good. LNG, nope.
Hmmmmm, it seems to me that most of the boiled off nat gas could be used to supplement the fuel used to drive the ship.
