Special Issue Information

Dear Colleagues,

Concentrating solar power (CSP), is, today, a renewable energy alternative to PV or wind in terms of energy management. Although these competitors are cheaper, coupling with energy storage now gives the advantage to CSP to be a relevant electric network input or even a reliable heat process source. Moreover, the scientific community is supporting continuous advances in improving known technologies and totally disruptive concepts.

Some examples of new advances are improvements to thermal oil solar fields, new thermodynamic cycle concepts, etc. Collecting information on these new advances in CSP is one of the goals of this Special Issue, focusing on the following ideas:

Concentrating solar power plant improvements;
O&M experiences;
Heat process concepts;
New thermodynamic concepts;
Disruptive CSP technologies and ideas;
Thermal energy storage;
Heat process production and management.

Abstract

In a previous work, a solar chimney power plant integrated with a solid sorption cooling system for power and cold cogeneration was developed. This prior work showed that reusing the heat released from the adsorption bed enhances the system’s utilization of solar energy and increases the turbine’s output power. In the present paper, a subsequent modification to the arrangement and operation of the preceding system is introduced. The primary objective of the modification is to enhance performance and increase the plant’s capacity to effectively harness the available solar radiation. The method involves placing the condenser tubes at the solar collector entrance. Therefore, the airflow captures the condenser-released heat before it enters the collector. The modified configuration and operation of the system are discussed. A dynamic mathematical model is established to simulate the hybrid system’s operation and evaluate its parameters. The obtained results show that a 5.95% increase in output power can be achieved by recovering the heat of condensation. Furthermore, the modified system attains a 6% increase in solar-to-electricity conversion efficiency compared with the basic system. The findings suggest that the modified system, which recycles condenser heat, provides noticeable enhanced performance compared with the basic system. Full article
