Is It Possible?
Hydrogen is a very light fuel. It contains three times more energy than jet fuel. So it is actually a better fuel for aviation than kerosene even. And then with fuel cell based propulsion, you can use that fuel up to two times more efficiently because you don't combust so your efficiency is higher. We just need to do the required amount of engineering to get to that level of power. But there are no scientific barriers in order to get there.
