STES systems use technologies such as aquifers, borehole thermal energy storage, and insulated water tanks to store thermal energy on a seasonal basis
Drake Landing Solar Community
The Drake Landing Solar Community in Alberta, Canada, demonstrates the success of STES by providing 97% of the community's space heating needs from solar energy
STES systems are particularly effective in regions with significant seasonal temperature variations and are instrumental in harnessing solar energy for year-round heating
Centralized solar district heating systems use large-scale solar collectors and thermal storage, such as concentrated solar thermal (CST) plants, to efficiently provide heating to multiple buildings within a district
These systems benefit from economies of scale and can efficiently manage the distribution of heat through a centralized network
By leveraging the thermal inertia of the storage medium, centralized solar district heating systems ensure a stable and sustainable heating supply, even during times of low solar irradiance
Interseasonal thermal energy storage can be achieved through methods such as the use of aquifers, underground pits, and insulated tanks, while short-term thermal storage utilizes materials with high thermal mass, such as stone, concrete, and water
These storage methods are essential for mitigating the mismatch between peak solar energy availability and peak heating demand, contributing to energy efficiency and thermal comfort
The integration of these storage methods into building design is a strategic approach to passive solar heating, providing a sustainable and cost-efficient alternative to conventional fuel-based systems
Solar cooling technologies, such as solar absorption and adsorption chillers, offer sustainable alternatives to conventional cooling systems
Solar ventilation systems, such as solar chimneys, utilize passive solar design principles to enhance natural ventilation, reducing the need for mechanical cooling and improving indoor air quality
Despite economic and climatic limitations, these technologies are gaining traction and are supported by research initiatives like the International Energy Agency's Solar Heating and Cooling program
