However, at ~80 min, the pumped storage starts and absorbs power, and the source of this power includes the battery; the battery is supplying energy to the pumped storage, which is because the battery SOC has exceeded 80% and reached its limit, and the pumped storage always works until the battery SOC is 50%, although the power of the wind-PV ...
[OC] Most cost-competitive technologies for energy storage
And its dominance has expanded towards shorter storage times over time. - Lithium Ion Battery storage gets worse if you have very frequent charge/discharge cycles - For very frequent but short storage a fly-wheel is best. But due to friction it cant store for long times. - Pumped hydro is best for storage of many hours, but only if used frequently.

Pump Up the Storage | Do the Math
Converting land to pumped storage carries far greater environmental impact than converting to a solar farm, so that storage concerns dominate. Wind takes substantially more land (about 50 times) than solar, so the pumped storage lakes would not rival the area dedicated to wind farms. Variations and Scalings
