Electrifying Maritime Shipping: Evaluating the CO<sub>2</sub> Reduction and Viability of Future Battery-Powered Container Ships Calling at the Port of Los Angeles
Bibliographic record
Abstract
Abstract Maritime shipping plays a pivotal role in global logistics, influencing efficiency, emissions, and adaptability. This academic study envisions future electrified shipping fleets and evaluates the potential for CO 2 reduction and the cost delta between grid electricity and marine fossil fuels using three types of container ships (5000-7999 TEU, 8000-11999 TEU, and 12000-14499 TEU). The scenario evaluated envisions an electrical charging infrastructure at the Port of Los Angeles, supported fully by wind and solar energy sources, to recharge future battery-powered ships. It is recognized that electric-powered ocean-going long-transit ships are not practical, but this study provides baseline groundwork to justify and support future development of hybrid or partially electric ships to help meet the International Maritime Organization’s (IMO) target of a 50% reduction in CO 2 emissions from the world’s shipping by 2050. Additionally, a real case study analysis of all container ships at POLA was conducted using container vessel activity to further evaluate the practical implications and benefits of this transition. This analysis underscores the significant electrical infrastructure investments required and highlights the potential economic challenges as well as the environmental benefits of integrating electric power into maritime operations.

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.
