Abstract

This work assesses the technical, economic and greenhouse gas (GHG) emission performance of different, low emission shipping options. It shows how the levelized cost of shipping (LCOS) and lifecycle GHG emissions depend not only on the fuels and propulsion systems used, but also on key vessel design parameters. A case study of a conventional, 250 kt deadweight, iron ore carrier is shown to have a similar LCOS as a 350 kt deadweight vessel with a reduced range, lower design speed and green hydrogen gas fuelling, without compromising on the cargo delivered over some period. The resulting ‘green premium’ is much smaller than historical iron ore price fluctuations and towards the lower end of the IMO’s currently discussed carbon price range, with similar results also achievable with other, low emission fuels. This suggests that significant increases in shipping costs may not be inevitable as carbon-based emission policies are implemented.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
