Abstract
A hybrid photovoltaic (PV)-biomass system with energy storage options is investigated based on energy and exergy analyses. The hybrid system consists of a photovoltaic system, an electrolyser, and a biomass gasifier, which is integrated with a biomass-based gas turbine. The PV system is accountable for 56% of the annual exergy destruction in the hybrid system, while 38% of the annual exergy destruction occurs in the biomass-gas turbine (GT) system. The overall energy and exergy efficiencies of the hybrid PV-biomass system with energy storage options are 34.8% and 34.1%, respectively. A 29% increase in both energy and exergy efficiencies is reported with an increase in the steam-to-carbon ratio (SC) in the range of 1–3 mol/mol. The related specific carbon dioxide emission reduction is 1441–583 g/kWh. In contrast to SC, an increase in gas turbine inlet temperature results in a negative effect on the overall energy and exergy efficiencies, and it does not make a significant contribution to the reduction in specific carbon dioxide emission.

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
