Hydrogen is very expensive compared to just batteries. The weight savings only make up for the horrible efficiency of hydrogen once you are looking at an airplane.
Just use a battery, really.
And put transport over distances that exceed one driver shift on trains.
- cachius 11mo agoThe weight reductions may reduce TCO by one fifth through increased capacity https://news.ycombinator.com/item?id=46075305#46078485 https://news.ycombinator.com/item?id=46075305#46078485 Plus no range reduction in cold conditions. Plus you can store hydrogen long-term for winter. And transport Liquid Hydrogen with huge energy density per truck/ship to remote places. https://www.thetruckersreport.com/truckingindustryforum/threads/the-cryo-hauler-thread.2472216/ https://www.thetruckersreport.com/truckingindustryforum/thre... Sounds like a win for northern quartersphere.
- seanmcdirmid 11mo agoYou need massive infrastructure investments to freeze it, vehicles are more expensive because the tanks need to freeze it, fuel in stations need to freeze it, tanker trucks that deliver it need to freeze it, there is a lot of energy lost in freezing snd heating it back up. China doesn’t feel rich enough to build all of that when charging stations are pretty straightforward and cheap. Probably the only thing holding back electric for long hauls now is the lack of infrastructure (grid is needed to build charging stations, and truckers prefer untolled routes without much of that), and also sunk costs on their existing trucks (which tend to last what feel likes forever with cheap repairs).
