An A380 at MTOM has about 15% payload (pax, cargo) and about
40% airplane, so a full 45% fuel. And kerosene has about 30 to 90x the specific energy (energy per mass) as current batteries, so for an electric airplane the numbers would be much worse. (Plus the Airbus doesn't have to carry the fuel it has burned, while an electric plane does have to carry the empty batteries.) TLDR: Long range air travel with batteries is a long time off. |
