Hydrogen is 120 mj/kg. Crude is 42ish mj/kj

Also crude oil has a higher volumetric energy density (MJ/L) than liquid hydrogen anyway, so not sure what math you used. Hydrogen has high energy density on a mass basis but it’s poor by volume due to low density, even when liquefied.
Because of the density difference, a barrel of crude oil contains more energy than a barrel of liquid hydrogen. It would take ~3.7 barrels of liquid hydrogen to equal the energy content of 1 barrel of crude oil.
It’s a bit of a moot point though since BOE isn’t actually based on volume anyway as I mentioned previously. A BOE basically means 6.1 GJ of energy content.
