Batteries are nonviable for Aircraft. Weight is serious issue with Aircraft.

Even Current Aircraft have problems with weight. A big part of the reason why Aircraft have to dump fuel before they land is becuese they are too heavy.

And for batteries to be able to power a commercial Aircraft they would need to be much denser. Which contributes to problem #1.

Might be solved decades into the future but for right now nothing is going to be changing when it comes to Aircraft since no viable alternatives are even close to being viable.

Including this Achievement the article is talking about. Since hydrogen has powered aircraft before.
