> Those periods of near zero production can last non-trivial amounts of time no realistic battery could provide for. Interestingly not the case. New Zealand is currently considering what would become the largest battery in the world, Lake Onslow. Consisting of a giant artificial lake and hydro dam it could store ~12 terawatt-hours. This would be enough to smooth over any variations in renewable load and remove the need for fossil fuel peaker plants.
