This paper proposes a strategic roadmap for Greece to decarbonize its coastal ferry sector by adopting Norway's electric and hybrid ferry innovations. It highlights two pilot initiatives—a hybrid retrofit for the Perama-Salamina route and a…

Aniruddha Bora, J. Chalfant, C. Chryssostomidis

International shipping accounts for ~3% of global GHG emissions, but routing remains heuristic. This paper presents PIER, an offline reinforcement learning framework integrating physics-informed state construction, that reduces mean CO2 emi…

Ruikai Sun, W. Abouarghoub, Emrah Demir +1

This study analyzes the environmental and economic impacts of rerouting shipping due to the 2024 Red Sea crisis. Using AIS data and modeling, it finds GHG emissions increase by 46% and costs by 51% when vessels take the Cape of Good Hope ro…

Doru Coșofreț, Florin Postolache, Adrian Popa +2

This paper proposes a hybrid digital CO2 emission-control technology for maritime transport using physics-informed adaptive speed optimization. It integrates exact optimization (Backtracking, Dynamic Programming) with reinforcement learning…

Kelsey Pailman

This paper analyzes EU and IMO legal frameworks for hydrogen-based fuels in maritime shipping, identifying regulatory challenges. Using the Hydrogen Prism framework, it evaluates cohesiveness, risk mitigation, and compliance, calling for al…

Mamdouh Elmallah, Ernesto Madariaga-Domínguez, M. Saadeldin +3

This study compares the economic viability of natural gas and methanol as alternative marine fuels for dual-fuel engine conversion in shipping. It calculates cost savings per ton of pollutant reduction (NOx, SOx, CO2, CO) relative to conven…

Runze Mao, Kai Liu, Jingfeng Liu +4

This review provides a data-driven comparative analysis of LNG, battery, and hydrogen fuel cell technologies for maritime decarbonization, analyzing 1,053 ships in operation as of 2023. It finds that LNG serves as a transitional solution co…

Z. Malakouti, M. Hazrati

This paper critically evaluates the extension of the EU Emissions Trading System (EU-ETS) to maritime shipping as of January 2024. Using a 'Just Framework', it identifies procedural, distributive, and cosmopolitan injustices arising from th…

Moses Adjei, Judith van Leeuwen, H. Pereira

This paper examines governance challenges and barriers to implementing the EU Emissions Trading System (ETS) in the shipping sector, analyzing design, enforcement, and international coordination issues that affect the effectiveness of decar…

Saana Ollila

This thesis analyzes the design and effects of carbon pricing in maritime shipping, combining four papers. It examines short-run responses (speed reduction, demand shifts) and long-run effects (R&D investment, alternative fuels, learning-by…

Lixin Shen, Xinglian Peng, Xinyu Liu +2

This study analyzes collaborative decarbonization between ports and shipping companies, incorporating vertical technology spillovers and joint benefit-cost sharing. Using an evolutionary game model combined with a scale-free network, it fin…
