6 FAQs about [Solar thermocline thermal storage]

Is thermocline a good thermal power storage system?

Thermocline is considered as a favorable solution for thermal power storage system that achieves cost reduction for concentrated solar power (CSP) plants. However, Thermocline uses a large quantity of material, often molten salts, in one or two huge tanks several tens of meters high and in diameter.

Can thermocline thermal energy storage reduce the cost of a plant?

The thermocline thermal energy storage (TTES) system has the potential to reduce the overall cost of the plant since most of the expensive storage fluid can be replaced by low cost filler material (Gil et al., 2010, Brosseau et al., 2005 ).

What is a thermocline storage tank?

In conventional design practice, a well-mixed storage tank is considered for storing the heat. A thermocline tank offers benefits like the uniformity of the output temperature and reduction in thermal losses from the solar collector, through the establishment of thermal stratification.

What is a single tank thermocline system?

The plants will use organic oil as the heat-transfer fluid and molten salt as the storage fluid. Single-tank thermocline systems store thermal energy in a solid medium—most commonly, silica sand—located in a single tank. At any time during operation, a portion of the medium is at high temperature, and a portion is at low temperature.

Is thermocline storage a good solution?

Thermocline storage on a solid bed is a promising solution but requires an adequate choice of the solid material used. In this literature review, it was found that vegetable oils have the same orders of magnitude in terms of thermal properties but their thermal stabilities allow them to be differentiated.
