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

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.
So indeed, an airport serving dozens or hundreds of electric aircrafts a day will need obscene amounts of electric energy.
- vardump 8mo agoJet engines are not 100% efficient. Electric motors can be pretty close, 98% is realistic. Of course other parts of the system will lose energy, like conversion losses. Of course that doesn't mean batteries are currently a viable replacement. One should still take efficiency into account in quick back of the envelope calculations.
- TheSpiceIsLife 8mo agoHalve it to 0.11G then. It makes no difference, we’d still need gigawatt scale electricity production, with some multiple of that at peak, just for a fairly unremarkable airport.
