Long-duration energy storage technology (duration longer than 100 h), such as renewable power to hydrogen and methanol, holds significant promise as a solution to ensure the reliability of power grids, particularly in renewable-dominated power grids .
First, our results suggest to industry and grid planners that the cost-effective duration for storage is closely tied to the grid's generation mix. Solar-dominant grids tend to need 6-to-8-h storage while wind-dominant grids have a greater need for 10-to-20-h storage.
Impacts of PV integration on net grid load The expansion of solar PV generation has the potential to considerably reshape the grid power load profile, leading to more frequent occurrences of electricity abundance and shortage.
This study models a zero-emissions Western North American grid to provide guidelines and understand the value of long-duration storage as a function of different generation mixes, transmission expansion decisions, storage costs, and storage mandates.
