So, why is making hydrogen from other energy source worse than filling up lithium batteries from other energy sources?
Hydrogen isn't a source of energy. It's a battery all the same.
There are efficient and inefficient ways to "charge" a battery. And as a result, there are efficient and inefficient batteries.
Lithium is easy and efficient to charge, but there's certainly environmental (and not to mention political and ethical) concerns around its mining and refinement.
Hydrogen is not. It does have a benefit of being a rather dense mechanism though. But storing and transporting it is a problem of itself due to how small hydrogen atoms are. There will always be leaks.
Thanks for the info.
Hydrogen is less efficient, so you waste energy and you have to transport hydrogen from producer to consumer, usually with gas powered vehicles anyway.
No the hydrogen is not a battery, it is gray hydrogen sourced from fossil gas or coal. This makes the hydrogen still a fossil fuel. Green hydrogen doesn't have this problem.
