Notes on the Economics of Energy Storage
As de Sisternes et al. (2016) note, "In general, while energy storage appears essential to enable decarbonization strategies dependent on very high shares of wind and solar energy, storage is not a requisite if a diverse mix of flexible, low-carbon power sources is employed, including flexible nuclear power.".
