4 Frequently Asked Questions about "Solar thermal power generation underground heat storage"

What is underground thermal energy storage?

Underground thermal energy storage, derived from indigenous sources within the earth, is a clean, renewable energy source. Compared with wind energy, solar battery energy and other renewable energy sources, the biggest advantage of underground thermal energy storage is the stable and continuous output of energy.

Should underground thermal energy storage be included in a future energy system?

Thus, a future energy system design should incorporate underground thermal energy storage (UTES) to avoid this temporal mismatch and emphasize thermal applications. Such a basis of design would introduce new methods of energy arbitrage, encourage adoption of geothermal systems, and decrease the carbon intensity of society.

What are underground thermal energy storage systems (Utes)?

Due to their large storage capacity, underground thermal energy storage systems (UTES) offer good conditions for seasonal heat storage. By storing heat during periods of surplus energy (e.g. in summer) and utilising it in winter, energy systems can be made significantly more efficient.

What are the different types of underground thermal energy storage?

Out of these, ATES and BTES are the most used forms of underground thermal energy storage, while CTES is rarely used commercially. ATES systems use groundwater to inject and extract thermal energy from and to the aquifer. The efficiency of this system depends on the size of the aquifer.
