The value of energy storage in decarbonizing the electricity …
Assuming a 30-year financial life of the asset, results show that the first 10 GW of 10-h duration storage avoids USD 103–257 per installed kWh (depending on emissions limit) in generation costs. The marginal value of storage declines to USD 80–160/kWh at 20 GW installed capacity and USD 91–112/kWh at 30 GW. 7.
