Environment & Energy

That doesn't make nuclear generated hydrogen a waste, since it can be generated by electrolysis with no fossil fuel involved.

Some amount of storage is useful enough to be worth the cost of conversion and wastage in storage.

The goal should be to make non-fossil energy abundant enough that it can economically replace all fossil hydrocarbon usages except perhaps a reduced amount of plastic, reduced by recycling and replacing usages with more durable metals or fibre like carbon fibre for longer terms and plant fibre for "disposable" uses (even then with some recycling).
