As far as I know carbon fiber is somewhat expensive to make too. That is a promising approach though. I imagine we'll see a combination of different battery approaches going forward optimized for different use cases. I do think we'll be seeing increasing amount of research going into this with electric vehicles and renewable energy becoming more common.
Burning hydrogen is clean actually, you get get water as exhaust. The problem with hydrogen is that most of it isn't produced in a clean way right now. Although, it is possible to do so. Volatility is also an issue, not sure if making a hydrogen battery could address that or not.
Different types of protons have different properties though. Liquefied hydrogen has around a quarter of energy density compared to gasoline, so that's not really great.
My understanding is that hydrogen has fairly low energy density which makes it of limited use for stuff like vehicles.
It's just different use cases for different tech. Sodium batteries are good for large scale energy storage facilities where size and weight doesn't matter, or vehicles that are meant to just get around in a city. For example, if you have a bus on a fixed route then a sodium battery works really great. Proton batteries have potential for applications where you do want to have high energy density, but they're always going to cost more than sodium.
They're in commercial use in China already. They have some disadvantages compared to lithium batteries as they don't hold as much charge, but they are a lot cheaper to make and don't require rare earth minerals.

Hey all, our favorite court jester is back to entertain us!
Reading books on daily basis. It's a qualitatively different experience from reading websites or consuming other form of media. If you have trouble getting into reading, I recommend picking a particular time and place, then reading at least a few pages every day. Eventually, it will turn into a habit and you'll be reading for longer periods. Another thing I recommend is finding books on topics you're interested in, be it fiction or non fiction, and don't feel bad about abandoning books if you find you're not enjoying it.
they really are :)
