Will, absolutely correct that the difficulty with producing hydrogen is the amount of energy that it takes to product hydrogen.
Advantage of hydrogen is that its storage requires simple and commonly available raw materials. Have not looked into whether the power cell requires a bunch of rare materials or not. In any event, the net sum of materials going into a hydrogen system (storage to power generation) does look like it uses a lot more commonly available materials than BEV alternatives.
Toward current paths of generating hydrogen, try looking at it this way. Yes, there are conversion losses in any energy system as less will always come out of the box than goes in. Advantage to generating hydrogen from water is that now we are able to do this with sustainable energy sources. Ok, sure, the best solar cell currently available is maybe 23% efficient, and then there is some loss from using that energy to split hydrogen and oxygen, and then some loss from pumping the hydrogen into storage, and then further losses in converting the hydrogen back to power at the wheels. Shoot, the total power taxation of the hydrogen from solar might actually make the ICE look *super* efficient and a BEV even more so. BUT, the hydrogen from solar / wind and water path is a fairly closed loop where the initial energy source (excluding the 'costs' to make solar cells and wind generators) is the sun and the exhaust products are heat and water. So, with all those conversion losses in the hydrogen system, it still looks like a very appealing deal to me
Seems at this point, the scale is starting to tip in hydrogen's direction (much to the anger of Musk) and it is a matter of how long it takes to scale-up production and improve efficiency in the generation process; not if.
