Efficiency is important for cost/economics but so is the abundance/scarcity. Fossil fuels are a non-renewable resource and are in theory supposed to get more scarce in the future driving up costs/economics while hydrogen is the most abundant element. Granted it is more cumbersome to capture, transport, store, and distribute it now, I don't think it's a outlandish theory that at some point in the future, technological improvement in hydrogen industry combined with more scarcity of oil could change the calculus on the cost/economics of oil vs hydrogen.
