There is no such thing as batteries for wind/solar. You have battery-based peaker plants and occasionally you may have the right geography to for pumped storage

There is no such thing as batteries for wind/solar. You have battery-based peaker plants and occasionally you may have the right geography to for pumped storage. But no, there is no battery storage technology capable of bridging the variability of wind/solar.
- extropy 6y agoWhy not? Its just a function of availability/price. Assuming some conservative numbers of 1kwh of batteries costs 100usd and can do 2k cycles, that results in extra 5cents per kwh. With the day/night cycle the utilization could be around 50%. Offset by only roughly half of your electricity needs to be stored. Sunless days would be pain though. Imo if combined with cheap solar can be competitive. FWIW my current electricity provider already applies a 1 cent/kwh surcharge for "peak capacity assurance".
