Are you sure the numbers are correct? Wikipedia lists LNG as 53.6 MJ/kg and 22.2 MJ/L and jet fuel as 43MJ/kg and 35MJ/L. 53.6 / 43 = 1.247 22.2 / 35 = 0.634

Are you sure the numbers are correct?
Wikipedia lists LNG as 53.6 MJ/kg and 22.2 MJ/L and jet fuel as 43MJ/kg and 35MJ/L.
53.6 / 43 = 1.247
22.2 / 35 = 0.634
Energy density by mass is higher than jet fuel. But it is higher by less than jet fuel's energy density by volume is higher than LNG. And LNG requires heavier tanks.
So all in all, if it's not absolutely needed because of the cooling advantages, LNG can store less energy in the fuel tanks.
- credit_guy 9mo agoYou are absolutely right. My 22% was a mistake, the correct number is indeed 36.5% lower volumetric energy density. But that strengthens my argument, doesn't it?
- vrighter 9mo agoyes i agree with you on it being unfeasible for most applications.
