Seasonal energy storage

What is seasonal thermal energy storage?

Generally speaking, seasonal thermal energy storage can be used by storing summer heat for winter use or storing winter cold for summer use, i.e., summer heat for winter use and winter cold for summer use. Common seasonal heat storage includes seasonal sensible heat storage, seasonal latent heat storage, and seasonal thermochemical heat storage.

What are the different types of thermal energy storage?

Sensible heat storage, latent heat storage, and thermochemical heat storage are the three most prevalent types of seasonal thermal energy storage. In recent years, latent heat storage based on phase change materials (PCMs) has made great progress in solar energy utilization.

Does seasonal thermal energy storage provide economic competitiveness against existing heating options?

Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.

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 seasonal storage?

Seasonal storage is, therefore, closely related to seasonal variations in temperature, wind speed and solar irradiation as these mainly determine the need for heat- and cooling demand and the generation of solar and wind power.
