Inter-seasonal thermal storage solar energy

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 .

Can a seasonal solar thermal energy storage system cover winter heating demand?

While the system aims to cover winter heating demand, its success depends on practical operating conditions and fluctuating ambient temperatures. Ma et al. assessed the viability of a seasonal solar thermal energy storage (SSTES) system utilizing ammonia-based chemisorption for residential use in the UK.

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 ].

Can thermochemical thermal energy storage be used in solar-powered buildings?

This study examines different thermochemical thermal energy storage (TES) technologies, particularly adsorbent materials used for seasonal heat storage in solar-powered building systems. This evaluation is confined to thermochemical energy storage devices with charging temperatures less than 140 °C.

What is solar thermal energy storage?

Solar thermal energy storage is used in many applications: buildings, concentrating solar power plants and industrial processes. Solar thermal water heaters capable of heating water during the day and storing the heated water for evening use are common. TES improves system performance by smoothing supply and demand and temperature fluctuations.

Why is thermal energy storage important?

In this perspective, thermal energy storage (TES) is essential in developing sustainable energy systems. Researchers examined thermochemical heat storage because of its benefits over sensible and latent heat storage systems, such as higher energy density and decreased heat loss.
