The talk is about liquefied gas. Bottled gas has way too low density to put it on a tanker. The losses are due to boil-off, not due to leakage.

- jillesvangurp 4y agoIn gas form, hydrogen is much worse. You need about 18 truckloads of hydrogen stored at 200 bar to match a single truck load of diesel in terms of energy.

Renders it inert, no losses and it doesn't even count as dangerous goods for land and sea freight. Seems to be pretty easy to get the H2 out of the oil for use or transfer.
- theshrike79 4y agoThe man in the keynote I linked was "Michael Liebreich, Chairman and CEO of Liebreich Associates, through which he provides advisory services and speaks on clean energy and transportation, smart infrastructure, technology, climate finance and sustainable development. In September 2020, he became an official adviser to the UK’s Board of Trade". ...and he didn't know of any better ways of transporting H2 than liquid form. If it would be "pretty easy" to absorb it to oils, I'm sure that would've been tried already. the industry's goal seems to be hydrogen->ammonia - transport - ammonia->hydrogen, because ammonia is orders of magnitude easier to transport.

And, in the low to mid volumes, the easiest way, which included distribution to smaller sites, was using carrier oil and standard oil tank containers. I would have to look the exact oil up again. Also true, as soon as one hits high volumes nothing beats liquified gas or pipelines.
