Hydrogen vs. Battery Electric Cars

I am not really convinced about the efficiency model you describe in this video, it seems rather biased. I am curious how much energy is lost via the 'well-to-tank' section, and how much is lost at the 'tank-to-wheel' part. Because 'well-to-tank' energy-loss would also applies to the kwh I consume at home. Which I would not believe to be very high, since that would imply that my energy supplier is sending me more energy than I use (hence, pay for). The 'tank-to-wheel' section argument is the 70~90% energy loss of getting the energy from the batteries into the wheels, and the conversion of AC to DC (which for some reason would not be part of the problem 70~90% energy loss as mentioned in the previous section). Real engineering has done a video about hydrogen a few years ago which might be worth to watch; https://www.youtube.com/watch?v=f7MzFfuNOtY. Could you please give more details (or souces) about this section of the video? Because currently it seems like a lot of bs.
