6 FAQs about [Principle of solar energy cross-seasonal heat storage]
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 .
What are heat storage methods for solar-driven cross-seasonal heating?
Heat storage methods for solar-driven cross-seasonal heating include tank thermal energy storage (TTES), pit thermal energy storage (PTES), borehole thermal energy storage (BTES), and aquifer thermal energy storage (ATES) 14, 15, 16. As heat storage volume increases, hot water preparation costs and heat loss per unit volume decrease.
Can solar thermal energy be used for cross-seasonal heating?
The increase in the tank temperature at the end of the heating period was beneficial for shortening the duration of the heat storage period for the following year. The feasibility of utilizing solar thermal energy and cascaded phase change heat storage for cross-seasonal heating has been demonstrated in this study.
Do solar thermal systems have seasonal storage?
Although storage capacities are significantly larger, solar thermal systems with seasonal storage systems typically have a capital cost of double that of a similar system with only short-term storage . Seasonal thermal storage is not only used with solar thermal heating systems, but is also commonly paired with heat pumps.
Why is cross-seasonal heat storage important?
The mismatch between solar radiation resources and building heating demand on a seasonal scale makes cross-seasonal heat storage a crucial technology, especially for plateau areas. Utilizing phase change materials with high energy density and stable heat output effectively improves energy storage efficiency.
Are thermochemical TES systems viable for seasonal solar energy storage?
Nevertheless sensible heat storage systems are still the prevalent technology for seasonal solar energy storage because of higher thermal stability and significantly lower cost of the involved storage materials compared to phase change materials (PCMs). On the other side there are thermochemical TES systems which are not yet commercially viable.
