Abstract
Hydrogen can be produced by decomposing water, through thermochemical cycles, in an environmentally benign manner using nuclear energy. The copper-chlorine (Cu-Cl) cycle is one of the most promising low-temperature thermochemical cycles and involves five main steps: HCl (g) production; oxygen production; copper (Cu) production; drying; hydrogen production. In this study, energy and exergy analyses are performed of the drying step of the Cu-Cl cycle for hydrogen production, considering its operational and environmental conditions. The evaluation considers efficiencies and various parametric studies are carried out of energetic and exergetic aspects, considering variable evaporator and reference-environment temperatures.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
