During the 2025 GREEN4SEA Athens Forum, Antonis Trakakis, Chairman of CIMAC Greece, discussed the challenges and opportunities for decarbonizing the maritime industry with a focus on hydrogen innovation. While hydrogen is considered a 'dream fuel' for decarbonization due to its zero CO2 emissions when burned, significant challenges exist in its production, storage, and transportation, hindering full adoption by the maritime sector. This has prompted exploration into alternative fuels like ammonia and methanol, which still have emissions issues without green energy sources. Carbon capture technologies, proven in other industries, offer promise for reducing CO2 emissions in shipping, despite complexities at sea. Innovations such as pre-combustion capture, hydrogen-powered engines, gas turbines, and fuel cells show potential for emission reduction and efficiency improvements. The article emphasizes the importance of balancing fuel and compliance costs while embracing new technologies to ensure the long-term sustainability of the maritime industry in its journey towards decarbonization.
