Hydrogen is a very powerful fuel, in fact, the most powerful and hot fuel. It's also eco-friendly. If we make profit from this, we can produce H2 turbojets a lot more powerful than kerosene ones. The only problem is that the concentration of hydrogen in our atmosphere is very low, and we need electrolysis to extract it from water. This process is very low efficient.
