Let's see, NOEM Green Hydrogen Company (currently building the largest green hydrogen plant, current planned capacity 600 tonnes daily). They planned to export hydrogen globally. I doubt it will be by pipeline. They will need more than one tanker.
I assume some of the companies planning on giga-Watt electrolyzers will need large tankers.
I see a couple of Toyota Mirais a day ( probably the same ones). They don't seem to have a problem finding hydrogen.
You seem to be more fixated on hydrogen than me. You post here more than I do. As I've mention several time, I consider the a gamble , not an investment. My interest is in green hydrogen. It's a possible solution to a pollution problem, thought about by our use of fossil fuels.
