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.
