Techno-Economic Analysis and Feasibility Study of a Solid Oxide Fuel Cell-Battery Hybrid System for Water Taxi Application
Bibliographic record
Abstract
A hybrid power system consisting of an intermediate temperature solid oxide fuel cell (SOFC) and a lithium-ion battery is conceptually designed for water taxi applications. The sizing method of such a hybrid system is developed based on the resistance, acceleration performance, cruising cycle, and the speeds of a water taxi under the conditions of daily operation time and charge neutrality over a 24 h period. A techno-economic analysis (TEA) is performed for the proposed hybrid system and compared with other two power sources, a typical internal combustion engine (ICE), and a battery-only system. A feasibility study based on the weight and the volume of the hybrid system is conducted. The potential reduction of greenhouse gases (GHG) emissions is calculated and compared with the GHG emissions from water taxies powered by an ICE and a battery-only, respectively.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
