It's a nice idea to think we can store electricity in liquid fuels and effectively run our planes on wind or solar power, but the numbers are not your friend. The chief of Europe's second largest airline presumably thought it was time to remind our planetary saviors that aviation really needs Avgas.  There is no realistic option to decarbonize flights.

German airline Lufthansa says it would consume half of Germany's electricity if it were to switch to green fuels

…while Lufthansa has tried to do its bit to adopt sustainable practices, the company's chief says that switching the airline to green fuels like e-kerosene could come at a big price—half of Germany's electricity supply.

"We would need around half of Germany's electricity to create enough of the fuels," Lufthansa's Carsten Spohr said at an aviation conference Monday, Bloomberg reported. He added that while green fuels made using renewable energy sources would help Lufthansa decarbonize its fuel consumption, the likelihood of having enough electricity to produce such materials was low.
