I’ll grant you that storage has gotten better since the decade now when I last worked on a hydrogen ICE project and yeah Toyota has made some good advances with their carbon fiber tanks now, heck of a lot better than the carbon fiber tanks that I had the pleasure of working with.
Last I read, the temperature changes were still issues with refilling station where they tended to ice up and with fatigue on the point of connection to the inlet due to temperature changes. If that’s been fixed or a solution has been found that’s great.
I think the biggest hurdles is still the transport, generation, and infrastructure and yeah, I can agree that tricky, expensive, slow development are all valid here.
And while I still don’t think the tech is there yet, I’m glad that progress is still being made and hopefully it’ll actually be viable in the future.
