The revised IMO GHG strategy sets ambitious and demanding targets with clearly defined timescales for the defossilisation of international shipping. Achieving these goals requires the rapid introduction and scaling of greenhouse-gas-friendly fuels and technologies. In the next decades, solutions such as methanol, ammonia, hydrogen and synthetic fuels will play a key role, with biomass-based fuels serving as an important bridge to enable immediate emissions reductions while long-term technologies mature.

Since the last RGMT in 2024, significant progress in research and development has been made. OEMs, component manufacturers and system suppliers have advanced future-ready engine concepts, fuel injection systems and retrofit solutions. These developments reflect the industry’s strong commitment to meeting regulatory requirements while ensuring operational reliability and economic feasibility.

The objective of this year’s conference is to review and critically discuss the most recent findings and new ideas. The 9th RGMT symposium provides a platform to share new concepts, practical experiences, validated test results and lessons learned from pilot projects and early commercial applications.

Particular attention will be given to the deeper technical aspects of applying future fuels. Discussions will address combustion characteristics, emission behaviour, efficiency impacts, safety and material considerations. Special focus will be placed on new technical solutions, adapted R&D methodologies, and emerging insights into the underlying physical and chemical processes.

Over the course of two days, the conference will enable an efficient and focused exchange between OEMs, component and system suppliers, research institutions and specialised R&D service providers. By bringing together expertise from across the value chain, the event aims to accelerate innovation, strengthen collaboration and contribute to the successful transformation of maritime propulsion systems toward climate neutrality.
