How does biodiesel energy density compare to diesel?

Biodiesel (B100) has ~90% of petroleum diesel's energy density (32.5 vs 36.3 MJ/L). B20 blend reduces energy density by ~2%. HVO (hydrotreated vegetable oil) is nearly identical to diesel at 34–35 MJ/L.

Is bioethanol less efficient than gasoline?

Ethanol has 21.3 MJ/L vs 32 MJ/L for gasoline — about 67% of the energy content. E10 blend reduces fuel economy by ~2–3%. Flex-fuel E85 vehicles see 15–27% lower MPG than gasoline.

What biofuel has the highest energy density?

HVO (hydrotreated vegetable oil) and hydroprocessed esters and fatty acids (HEFA) are the most energy-dense biofuels at 34–35 MJ/L, essentially equivalent to their fossil fuel counterparts.
