Yep, and that's a very legitimate concern and why I'm certainly not bullish about hydrogen. I just don't want to reflexively throw it out; sufficient energy production from clean sources would make electrolysis quite reasonable, even if it's not ideal, and there are approaches to handling the storage, too, if that ends up being the last bit. I suspect, based on current trends and sciences, that we'll see better batteries instead, but I don't see harm in continuing to look at hydrogen for now.
It is also difficult to store, so I suspect the hydrogen ship has sailed.
