It isn't going to overtake electric cars, too inefficient.

But it might be the future for airplanes, which need a lot more energy density.

Specifically density by weight. By volume, which is more important to cars, hydrogen also loses.

Yes also cargo ships and possibly American sized semi trucks. Although semis are right on border of battety vs hydrogen.

"American sized?"

There are semis all over the world...

Yean but aren't the trucks in america large. I have seen memes making fun american semi compared to smaller loris.

The trucks in Japan and Europe honestly seemed just as large, albeit the can be were shorter. But then there is Canada and Mexico which trucks are identical.

The problem with long distance airliners though is that the turbofan powered engine has such a huge power output that is only possible using a turbine.
