But yeah hydrogen might make sense for trucking or airplanes or boats.
Ah cool I didn't have an exact number. Will check out the video, thanks!

Ah darn, you're right.
I think what is also a described issue is that currently for power grids, we're sorta required to produce power on demand. Power storage isn't really economically appropriate long term because it will be hit by that same resource bottle neck that is currently projected. I've read some comment about how the storage could be the cars themselves one day where we can send that stored power from a car back into the system, but it seems just dumb.
The difficulty with understanding hydrogen is that it is intentionally complicated because in the long run, we need a flexible system to address complicated differences in possible scenarios produce and store electricity in a more environmentally conscious way. What's also often confusing is how the skipping of explaining how hydrogen is the energy, fuel and the storage like traditional oil and gas currently is. It's kinda glossed over that an EV concept is actually separating the lines between energy, fuel and storage. By trying to make the assumption that the EV cycle is the simple one, it makes all of the other ones more confusing and complicated by default.
I think it's also confusing because in the hydrogen "cycle", it's obviously not as efficient as the EV storage "cycle" and is unlikely to be that way for a long, long time. But the EV battery storage "cycle" is only for motor vehicles and doesn't address other things that would need electricity like hydrogen cells potentially could (housing, heating etc.). It's like saying a car headlight isn't as efficient as a hand held flash light and missing the point that a car can do more than just shine light like a flash light, but I'm not totally sure.
Although it takes a ton of power to produce hydrogen, in the super long term, hydrogen cell part actually can split into two where it's converted into electricity for cars, or electricity for other electrical grid needs. So for instance, I think we could use solar and wind and store it into hydrogen/cells when output is plentiful and then use the cells to keep things stable when there's less solar/wind or those units are down for maintenance. Hydrogen cells would replace more than just motor vehicle energy requirements, they might end up replacing LNG/Propane etc. type concepts as well.
The renewable and non-renewable part is also convoluted because it will address the concepts of green, turquoise, blue and grey hydrogen based on the source used to produce it. That's its own confusing chaos, but I'm also assuming it means that it allows different countries with different access to power generation different means to reach a planned ubiquitous "hydrogen cell standard" in the long run.
"Colored hydrogen wise" I think it'd be kinda cool to have something like a nuclear reactor that powers a grid and puts excess into hydrogen cells. When demand is higher, it produces less hydrogen cells and vice versa. But I also believe that not all hydrogen can and should be green/turquoise and that we need to intentionally have grey hydrogen. Grey hydrogen would be like producing energy by incinerating garbage. Looking bigger, I don't know if it's sustainable to be burying disposable #### in the ground that takes 30+ years to break down. IMO we should burn and store small concentrated volumes of this stuff in the ground or figure out how to utilize the created carbon in a more intentionally cyclical manner... but that's a different topic. In theory those things could be like your furnace at home vs trucking that stuff to a centralized location... but that's also a different topic.
