Modeling of a solar receiver–reactor for sulfur-based thermochemical cycles for hydrogen generation [PDF]

, 2011
Sulfur based thermochemical cycles for hydrogen generation from water have one reaction step in common which is the decomposition of sulfuric acid as one of the most energy consuming steps.

Infrared-reflective coating on fused silica for a solar high-temperature receiver [PDF]

, 2022
Art. 021004, 7 S.In concentrating solar power, high-temperature solar receivers can provide heat to highly efficient cycles for electricity or chemical production. Excessive heating of the fused-silica window and the resulting recrystallization are major

Assessment of Performance Enhancement Potential of a High-Temperature Parabolic Trough Collector System Combining the Optimized IR-Reflectors

Applied Sciences, 2020
Heat collecting elements (HCEs) are the core components in the parabolic trough collector (PTC) system because photothermal conversion of the whole system occurs in the HCEs.

Development of a mechanical mixing system of sensible heat storage equipment for a beam down solar concentrator

Nihon Kikai Gakkai ronbunshu, 2016
One of the merits of a solar thermal utility is that the cost of heat storage is lower than that of an electrical battery. Furthermore, a power generation system using solar thermal energy with heat storage equipment is capable of stabilizing its output.

Thermodynamic Analysis of a Conceptual Fixed-Bed Solar Thermochemical Cavity Receiver–Reactor Array for Water Splitting Via Ceria Redox Cycling

Frontiers in Energy Research, 2021
We propose a novel solar thermochemical receiver–reactor array concept for hydrogen production via ceria redox cycling. The receiver–reactor array can improve the solar-to-fuel efficiency by realizing the heat recuperation, reduction, and oxidation ...

3D-Printed Solar Cavity Receiver for Heating Pressurized Air – A Preliminary Evaluation

SolarPACES Conference Proceedings
High-temperature solar receivers experience non-uniform solar flux, which induces thermal stress in the receiver tubes. This stress is more pronounced in gas solar receivers due to the lower thermal conductivity of gases.

Effect of charging of phase change material in vertical and horizontal rectangular enclosures in a concentrated solar receiver

Case Studies in Thermal Engineering, 2020
The charging of phase change material (PCM) in a concentrated solar receiver is experimentally carried out in a parabolic dish collector. Rectangular PCM filled enclosures of 30 mm width in the solar receiver are investigated to study the effect of ...

Multi-Scale Modelling of a Solar Reactor for the High-Temperature Step of a Sulphur-Iodine-Based Water Splitting Cycle [PDF]

, 2011
The 3-step sulphur-iodine-based thermochemical cycle for splitting water is considered. The high temperature step of the closed-material cycle consists of evaporation, decomposition, and reduction of sulphuric acid to SO2 using concentrated solar process
