How can you accurately project costs of grid-scale store 1 or 2 decades into the future? It is an industry that is just starting out and projected to grow quite large. Profits and manufacturing labor account for greater than 50% of the battery costs now, so there is a good bit of room for prices to fall as manufacturing ramps up and the market becomes more competitive.

It is going to be in the trillions barring some radical revolution in storage that is unlikely given our breadth of knowledge of physics at this point. A lot of people think that Tesla Megapacks here and there are enough but those cover interruptions on the scale of minutes, not hours or days.
- xyzzyz 3y agoYou don’t need to be very accurate, because the cost of storage is enormous even if you’re off by factor of 5. Try it yourself: start from here https://www.eia.gov/energyexplained/us-energy-facts/ https://www.eia.gov/energyexplained/us-energy-facts/ and calculate how much it would cost to store one day of energy use in US.
