An A320 can store 24k liters of fuel. Jet fuel stores 35 MJ/L. So, the plane carries 8.4E11 J of energy. If that was stored in a battery that had to be charged in an hour 0.23GW of electric power would be required.
replySo indeed, an airport serving dozens or hundreds of electric aircrafts a day will need obscene amounts of electric energy.
Jet engines are not 100% efficient.
replyElectric motors can be pretty close, 98% is realistic. Of course other parts of the system will lose energy, like conversion losses.
You laid it out better than I. Thank you!
replyThanks Walter!
