We're going to get a 4x energy density improvement from lithium sulfur batteries, just as soon as production ramps up.

Wikipedia lists the energy density of kerosene as 9.7k Wh/L, and lithium sulfur at 550 Wh/L, which is not great.

Hydrogen isn't so great either.

But burning kerosene is much less efficient, and turbine engines have a much lower power density than electric motors, so knock 2/3rds off the the kerosene number.

550 Wh/L would also be for the first lithium sulfur batteries to market, they'll double that down the road.
