Abstract
Hydrogen energy systems are being developed to replace fossil fuels–based systems for transportation and stationary application. One of the challenges facing the widespread adoption of hydrogen as an energy vector is the lack of an efficient, economical, and sustainable method of hydrogen production. In the short term, hydrogen produced from fossil fuels will facilitate a transition to the hydrogen economy. In the long term, renewable hydrogen production methods will have to be adopted as resources become scarce, causing the price of fossil fuels to rise. In this work, a number of methods have been considered for the renewable production of solar hydrogen, and thermochemical sulphur-iodine cycles proved to be the most promising. The sulphur-iodine cycles have the highest efficiencies and use widely available reactants with relatively straightforward reaction mechanisms, which make them the most economical and technically feasible option for renewable hydrogen production.

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
