What is seasonal thermal energy storage (STES)?

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season.

Are seasonal energy storage technologies limiting commercial deployment?

This paper reviews selected seasonal energy storage technologies, outlines potential use cases for electric utilities, identifies the technical challenges that could limit successful commercial deployment, describes developer initiatives to address those challenges, and includes estimated timelines to reach commercial deployment.

Which energy storage system is best for managing seasonal demand?

Among these power-to-gas and compressed-air energy storage are considered more promising options than CSP + TES (sensible and latent thermal storage system) storage for managing seasonal demand in the future energy system.

Why is seasonal energy storage important?

These low-carbon energy sources also tend to abate during the fall and winter months. To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another.

Can seasonal energy storage be economically viable?

To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. Storage of this nature is expected to have output durations from 500 to 1000 hours or more.

What are the different types of seasonal heat storage?

Common seasonal heat storage includes seasonal sensible heat storage, seasonal latent heat storage, and seasonal thermochemical heat storage. Among them, both sensible and latent heat are used to store solar energy directly in the material.
