Why would you convert the hydrogen to electricity instead of burning it in the jet engine?
- AbrahamParangi 5y agoBurning it in our nitrogen- rich atmosphere creates NOx which is bad
- bell-cot 5y agoBecause the efficiency of hydrogen-burning jet engines is not substantially better than that of kerosene-burning jet engines? Vs. a fuel cell/motor/propeller system could be much more efficient?
