Decarbonisation is both a challenge and an opportunity for the maritime sector. This presentation on The Maritime Energy Transition highlights the urgent need for decarbonization in the shipping industry, which contributes nearly 3% of global greenhouse gas emissions. It explores emerging low- and zero-carbon marine fuels such as hydrogen, ammonia, methanol, and biofuels, etc. The session outlines recent regulatory milestones, including the IMO’s revised GHG strategy, the inclusion of shipping in the EU ETS, and evolving IACS and USCG standards. It emphasizes the critical role of Classification Societies in enabling innovation through technical assurance, risk-based approvals, and collaborative pilot projects. A real-world example is given to demonstrate how the energy transition novel technologies are advancing from concept to operational deployment for maritime applications. The presentation concludes by addressing infrastructure readiness, key challenges, and the opportunities for first movers in this rapidly evolving landscape.
