If only there were some way to take energy made from sunshine and store it in some form for later. Like in a battery. Or as heat. Or in a flywheel. Or just use the energy for something we'd really like to do as cheaply as possible. Like sequester CO2. Or desalinate water. Or run industries that would otherwise use natural gas.
Or use it to generate hydrogen for simpler, cheaper, more reliable, sustainable hydrogen powered cars.
We don't even have enough lithium to replace the average country's existing cars, let alone all of them, or literally anything else that requires lithium.
There are a lot more ways to store energy other than lithium and hydrogen.
Pumped storage, vanadium redox battery, sodium battery, ... I'd even say they are most suited for grid-level energy storage.
