Abstract
Current techniques of hydrogen production (primarily reformation of fossil fuels) are\nunsustainable, releasing CO2 into the atmosphere, as well as consuming limited reserves\nof fossil fuels. The copper-chlorine cycle is a promising thermochemical process which\ncan cost-effectively produce hydrogen with less environmental impact. In this thesis, new\npredictive formulations and experimental data are presented to improve the conversion\nextent and reaction rates of the hydrolysis reactor in the Cu-Cl cycle. This reactor has\ncritical implications for the design, operation, and efficiency of the Cu-Cl cycle and\nhydrogen production. The relatively high temperature needed to drive the reaction\nrequires a significant input of thermal energy. This thesis focuses on methods and\nanalysis to reduce the unreacted steam in the hydrolysis reactor, in order to reduce the\nthermal energy input and improve the cycle???s thermal efficiency. A key outcome from\nthis thesis is the experimental verification of reducing the steam to copper chloride ratio\nfrom 16:1 (past studies) to about 3:1. The results of this thesis provide key new data to\ndesign a more efficient hydrolysis reactor that can be effectively integrated within the\nCu-Cl cycle.

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
