Thermocline Storage for Concentrated Solar Power

The Master thesis hereby presented describes the modelling and implementation of a thermocline-like multi-layered single tank storage in a STPP. The research work presents a comprehensive methodology to determine under which market structures such devices can outperform the more conventional two tank storage systems.

Geometrical and PCM optimization of a thermocline energy storage system

This work presents an optimized thermal energy storage (TES) system based on thermocline technology. A prototype of a single-medium (molten salt) thermocline storage system was built and tested at the ENEA Casaccia Research Center, which consists of a single tank equipped with an internal vertical channel to drive the salt motion by natural convection.

Development of a Molten-Salt Thermocline Thermal Storage

indirect thermal storage system by assessing the feasibility of us-ing molten salt in a thermocline. We chose to study a thermocline system because it has the potential to reduce the cost of the ther-mal storage system and it can dispatch thermal energy at nearly a constant temperature over most of its discharge cycle.

Stability analysis of the thermocline thermal energy storage system

Hence, to understand the stability of the thermocline, it is pertinent to prudently design a thermal energy storage system. The thin thermocline is desirable for thermal energy storage systems concluded (Gil et al., 2010, Medrano et al., 2010). For a clear understanding, this novel study discusses the size and stability of the thermocline along

Solar Thermocline Storage Systems: Preliminary Design Study

To date, TES systems have been prohibitively expensive except in certain markets. Two of the most significant capital costs in a TES system are the storage medium (typically molten salt) and the storage tanks. Thermocline storage is a relatively unproven TES method that has the potential to significantly reduce these costs.

6 FAQs about [Thermocline storage system Sweden]

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.

What is a thermocline system?

What are the latest advances in thermal storage based thermocline?

The latest advances in thermal storage based thermocline are reviewed. The current project of solar collectors using thermocline storage thermal is reviewed. Enhancement of different parts of thermocline system is discussed. Theoretical models characterizing the storage performance are summarized.

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.

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.

Could thermocline reduce the cost of storage in CSP?

Thermocline seems to be a very promising technology and could significantly reduce the cost of storage in CSP.
