Abstract

Graphical abstract: Highlights: A proof-of-concept gas turbine–solar particle heating hybrid system was developed. The particle heating receiver is able to heat the falling particles up to 720 °C. Harnessing solar energy was demonstrated. Utilizing the stored thermal energy during off-sun operation was demonstrated. Excessive heat loss was traced and estimated. Abstract: The world's first integrated gas turbine–solar particle heating hybrid system has been realized on the campus of King Saud University (KSU), Saudi Arabia. The system was built and tested as a proof-of-concept, such that, upon successful completion of the test, a larger, commercial-scale system can be built with confidence. The successful execution of this project has yielded the following important observations: (1) the particle's central receiver system can heat the falling particles to 720 °C; (2) the hybrid system can store solar thermal energy in particles and transfer this energy (via a particle-to-working-fluid heat exchanger) to the compressed air before entering the microturbine.; (3) the microturbine can still operate using the stored thermal energy even after the solar field was shut down; (4) although the temperature rise of the compressed air across the heat exchanger was not high, it was adequate to prove the system's ability to use the particles' stored energy as a heat source.
