Reply to comment by Emeraldstorm3 in Hydrogen fuel from the ocean? Scientists say they’ve found a way to do it. Author Ling Tao, a professor at Tianjin University’s School of Materials Science and Engineering, said the new technology was compatible with existing electrolysers that currently use fresh water by chopchopped

It's got a higher energy density than lithium ion batteries, and as it can technically be produced without emitting hydrogen, it's a good fuel for planes etc that can't really carry really have batteries . And in a future with abundant fusion energy, electrolysis could be feasible, allowing for green air travel that doesn't have to stop frequently to recharge/swap out batteries

If we get to a point where we aren't emitting greenhouse gases in order to get hydrogen from water, that might help... for some niche applications, such as airlines. Logistics is still a problem as is volitility and the energy required to store it under explosive pressure so that it has a decent energy density. And that's only if we don't have better options for airplanes (or maybe cargo ships) by the time creating hydrogen isn't as much of a pollutant. And assuming battery technology doesn't improve.

I wouldn't say airplanes are really a niche application
