What types of energy storage are suited for seasonal storage?

Two forms of storage are suited for seasonal storage: green hydrogen, produced via electrolysis and thermal energy storage (such as pumped thermal energy storage for electricity). As the round-trip efficiency is low, significant hydrogen needs to be stored. Energy storage is one option to making grids more flexible.
