The Mapping of Zero-Emission Pilots and Demonstration Projects has, since 2020, presented snapshots of the evolving landscape of innovation in zero-emission shipping across ship technologies, fuel production technologies, bunkering, and infrastructure. This fifth edition documents a major milestone in shipping’s decarbonisation journey, as many of the activities, technologies, and projects formerly covered by this report have matured beyond piloting and demonstration and begun to focus on commercial deployment and are thus excluded from this year’s report. Many new projects have also been added, with a majority of those announced in 2023 and early 2024. Projects previously included in earlier reports continue to evolve, with an increase in projects receiving approvals in principle (AiP), indicating continued positive progress towards commercialisation. For those projects, new and old, that have disclosed their timelines, most expect completion in or after 2025.
The progression of these projects underscores continued momentum in maritime decarbonisation, as the industry moves from testing and demonstration to implementing viable, commercial zero-emission solutions, marking a crucial step toward sustainable shipping.
