...Adam C. Gladen; Dilpreet Bajwa One promising thermochemical reaction for energy storage is the hydration of hygroscopic salts. However, pure salts have poor cycle stability. The present work investigates a new composite material by impregnating a framework of crystalline nanocellulose (CNC...

...Bo Wang; Lifeng Li; Johannes J. Pottas; Roman Bader; Peter B. Kreider; Vincent M. Wheeler; Wojciech Lipiński A transient heat transfer model is developed to study the thermal performance of a high-temperature solar thermochemical reactor for metal oxide reduction. The solar reactor consists...

...Kangjae Lee; Jonathan R. Scheffe A 200 W CO 2 laser-based heating system coupled with in operando Raman spectroscopy has been developed. The system delivers highly concentrated radiation capable of driving thermochemical reactions and simulates heat fluxes expected by 3D solar concentrating systems...

... the numerous thermochemical cycles proposed for splitting H 2 O and CO 2 using concentrated solar process heat [ 1–3 ], the one based on the Zn/ZnO redox reactions emerges as promising due to its potential for reaching high efficiency [ 4 , 5 ]. This two-step redox cycle consists of: (1) an endothermic high...

... systems. This elevated placement enables improved optical performance, possibly to such an extent that a terminal concentrator at the reactor aperture would not be necessary. Initial results in all four areas are very encouraging and will be reported separately. Solar-thermochemical reactors...

...Richard B. Diver; James E. Miller; Mark D. Allendorf; Nathan P. Siegel; Roy E. Hogan Thermochemical cycles are a type of heat engine that utilize high-temperature heat to produce chemical work. Like their mechanical work producing counterparts, their efficiency depends on the operating temperature...
