> because physics dictates using hydrogen will always be much less efficient compared to direct electricity use

You have to look at the whole system (and life-cycle) and not just compare single trains. I assume people with enough insight and expertise did the math and they don't just try this tech out for fun.

EDIT: Also looking at the video, the giant transformators you usually have in a Lok aren't there. That weight difference already could make hydrogen competitive.
