It can be, but it takes a huge amount of power to do it, and the biggest hydrogen production method (reforming) produces GHGs itself
So what? Build solar plants in Africa, pump out hydrogen, keep flying as often as you want emissions free. It is a solution and as such a hydrogen plane is a massive advancement towards a sustainable future for the aviation. Whether it will turn oit this way is a different question.
Make it with nuclear power. Turn water to hydrogen and oxygen. Release the oxygen. Package the hydrogen. Burn the hydrogen and it mixes with the oxygen. Maybe eject the spent radioactive fuel into space some day?
ok brb
Disposing of radioactive material via space is not a great idea. Not to mention the cost inefficiencies, the risk of something going wrong with the rocket and spreading nuclear material all over the place is non-zero.
Nothing has zero risk attached. We’re pumping radioactive material into the atmosphere all the time in coal power plants, and nobody bats an eye. This isn’t even a failure condition, this is just normal.
