What is seasonal storage?

Seasonal storage is defined as the ability to store energy for days, weeks or months to compensate for a longer term supply disruption or seasonal variability on the supply and demand sides of the energy system (e.g., storing heat in the summer for use in the winter via underground thermal energy storage systems) [ 12 ].

What is seasonal thermal energy storage (STES)?

Using excess heat collected in the summer to compensate for the heat supply insufficiency during the wintertime is the concept of seasonal thermal energy storage (STES), also called long-term heat storage.

Why is seasonal energy storage important?

Energy storage at all timescales, including the seasonal scale, plays a pivotal role in enabling increased penetration levels of wind and solar photovoltaic energy sources in power systems.

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.

What is the role of energy storage at the seasonal scale?

Abstract and Figures Energy storage at all timescales, including the seasonal scale, plays a pivotal role in enabling increased penetration levels of wind and solar photovoltaic energy sources in power systems. Grid-integrated seasonal...

What technologies are available for seasonal heat storage?

It widens the use of solar collectors and results in better solar coverage of the space heating demand. This paper reviews all three available technologies for seasonal heat storage: sensible heat storage, latent heat storage and chemical storage.
