Seasonal energy storage application case

What is seasonal thermal energy storage (STES)?

Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand .

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.

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.

Can thermochemical seasonal energy storage system be used for solar district heating?

The present article explored the potential of the thermochemical seasonal energy storage system using MgO/Mg (OH) 2 system for solar district heating applications in China. The solar district heating model with thermochemical seasonal energy storage system, including the parabolic trough solar collector and a chemical reactor, has been built.

Do seasonal solar thermal energy storage systems have dynamic charging/discharging performance?

The dynamic charging/discharging performance of the seasonal solar thermal energy storage system has been simulated and analyzed by using the real weather data and the practical domestic heating demand. The optimal parameters of the equipment have been identified.

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.
