The problem with the comparison is hydrocarbons are the energy source, hydrogen is no it’s just the energy carrier. It is very inefficient to convert energy to hydrogen then convert it back again. Something like 60% round trip efficiency. Not to mention the cost and loss in loading into containers and shipping it around the world. It’s also not a very dense fuel per volume especially compared to oil. It’s just way easier and cheaper to have cables that run from one place to another. They are already building one from Australia to Singapore and if it’s successful that will probably open the floodgates. There aren’t many places that are more than 2000 miles away from large sources of renewable energy even if your thinking places like Alaska which could do hydro if there ever was dense enough populations anywhere that would consume it.
