re: Stated at CERAWeek: Hydrogen adoption will cost Europe, US more than $1 trillion

What does this mean? Is it saying the equivalent energy you get from a barrel of oil that you would get from a “barrel of hydrogen is the same or are we just comparing volumes? Because hydrogen at $200/barrel is less expensive on a $/mj basis when compared to today’s price for a barrel of oil ($86.96)

And is that the current price of hydrogen or a projected future price once production ramps up significantly? Because if current prices it's meaningless, the price will no doubt drop considerably.

BOE (barrels of oil equivalent) is a measure of energy content, not volume or mass.

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.
