Exergy Analysis of the Discharge of Sensible Heat Thermal Energy Storage Systems: Granular Material vs. Solid Blocks

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(5), P. 2543 - 2543

Published: Feb. 27, 2025

Thermal energy storage (TES) systems are essential components of concentrating solar power (CSP) plants that enable uniform generation green electricity and process heat. The performance sensible heat TES based on granular material solid blocks was experimentally analyzed during the discharge process. A system studied in its operation as a regular fluidized bed confined restricted motion via mechanical confinement. pressure drop required to circulate transfer fluid (HTF) through made alumina measured be two orders magnitude lower than used system, being close 0.2 bar for decreasing from 0.65 0.3 bed. evolution exergy efficiency along determined by obtaining an inversed exponential reduction parabolic block roughly value system. considering HTF parasitic consumption plant, remained higher 90% complete

Tailoring solar-assisted calcium looping for polyethylene terephthalate (PET) steam gasification: Combined effect of carbonation and calcination temperatures on process performance

Applied Energy, Journal Year: 2024, Volume and Issue: 376, P. 124269 - 124269

The solar-assisted calcium looping process has gained more and interest in recent years. It allows both the capture of CO2 storage solar energy during sorbent regeneration, removing request auxiliary fuels for heat supply. effect carbonation or calcination temperatures on performance been widely studied but mainly based individual factors. This study investigated combined deactivation carrying capacity a (10 calcination‑carbonation cycles) directly irradiated fluidized bed, to obtain optimized operating with conceptual reference integration polyethylene terephthalate (PET) steam gasification. were 600–700 °C 800–900 °C, respectively, while inlet concentration was set at 10%v following previous results PET experimental showed that increasing promoted deactivation, temperature had negligible effect. Fitting parameters models obtained by varying performed well prediction, which broadens application these different temperatures. best condition maximal averaged degree 600 800 °C. However, considering hydrogen yield transfer gasification, second-best (carbonation 650 850 °C) would be preferable gasification process. optimization all combinations provided, so required can accordingly chosen also other processes looping.
