HySeas III: The World's First Sea-Going Hydrogen-Powered Ferry – A Look at its Technical Aspects, Market Perspectives and Environmental Impacts
Bibliographic record
Abstract
The greenhouse gas emissions from international shipping were estimated to be 2.1% of the global emissions by 2012. In order to decrease them in the future, new measures are being taken but also new alternative power systems employing batteries, hydrogen and fuel cells and the production of alternative fuels are now under development. Currently, several projects are aiming at the implementation of hydrogen and fuel cells in Ro-on/roll-off and passenger (RoPax) ferries. In relation to this, a comparison of hydrogen and fuel cell systems against other technologies such as batteries in terms of costs, system mass and volume is presented in this paper. In addition, an overview of the market potential of RoPax ferries in Europe is given, showing that fuel cells have potential, particularly if their power is scaled up. Finally, we present the first results of the life cycle assessment carried out within the project of HySeas III, which shows that the global warming potential generated by the ship in a 30 year life would decrease by 89% compared to a ship operating with a diesel-electric system.

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; both teacher heads agree on what is shown here.
