We already need it. During summer we have an overabundance of energy. It would be so nice to have it stored and used in winter, wouldn't it?
Oh wait. "Cheap storage" in no way, shape or form translate into efficient storage. You might have to cover half of Europe in batteries to store just a few weeks worth of energy.
- pfdietz 4y agoUsing batteries to store weeks worth of energy would be foolish. Batteries are too expensive per unit of energy storage capacity. They're suited for diurnal storage. Long term storage doesn't need to be efficient, because the number of charge/discharge cycles is small and the "cost of inefficiency" is proportional to the number of such cycles.
