I didn’t think about hydrogen powered shipping container ships. That sounds like a good use case.
My main issue with hydrogen is that most of it is produced using some natural gas / fossil fuel thing I don’t understand. AKA Dirty hydrogen. Producing hydrogen using green tech is super inefficient compared to storing green energy in batteries. Personally, I think better battery tech like sodium Ion that uses cheap and recyclable materials are the better option for most applications.
I do have a personal conspiracy theory that fossil fuel is pushing for hydrogen to slow green tech epically since the cheap way to make hydrogen is with fossil fuels.
Another thing about hydrogen is storage and transportation. To store it long term you need to cool it a liquid form which is really hard to do. Also, current hydrogen fuel cell are low efficiency and low power density. That’s why the toyota miria uses a fuel cell to charge a battery which powers the car.Tthe fuel cell can’t put out high current.
Most of what I know about hydrogen tech came from the aging wheels video about Mirai. So I might be super wrong about everything. I do recommend giving it a watch though: https://www.youtube.com/watch?v=rtZQLUtckS4
You’re definitely not wrong. Gray hydrogen currently is the most common source, which is a byproduct or an intended product of petroleum cracking. This also is probably a reason why most petroleum companies chose to research hydrogen in the 2000s/2010s rather than battery or other renewable technologies, since it fits nicely in their existing pipelines.
For storage, I’m pretty sure you can keep it at atmospheric pressure and temperature if space isn’t an issue, but to actually fit it in a vehicle you’d probably have to use one of the techniques you mentioned.
The Mirai’s issues seem to be that it was just a foothold for consumer hydrogen without anything really backing it. You could almost say the same about EVs/PHEVs 15 years ago and look at them now.
Honestly though, if we are able to scale up sodium batteries, grid storage and train usage might be moot. Ships could probably still use it as an alternative to diesel though.
