The Green Transition: Advancements and Challenges in Maritime Propulsion

The maritime industry is seeking technological solutions to transition to green propulsion, including battery-electric, hydrogen, and wind-assisted propulsion. The Zero Emissions Ship Technology Association (ZESTAs) is an industry body that represents green-propulsion companies. Madahd MacLaine, CEO of ZEM Tech and Secretary General of ZESTAs, discussed the changes in green propulsion and the commercial prospects of these technologies. MacLaine noted that there has been a significant shift towards hydrogen and the increased power density of battery-electric energy storage systems. The commercial viability of fully electric vessels is becoming more favorable, especially when there is access to abundant renewable energy for charging. Wind propulsion is also gaining success due to its fuel-saving benefits. However, stricter regulations and market-based measures are needed to drive the adoption of hydrogen technology.

MacLaine believes that a market-based measure document can be agreed upon at MEPC 81, with significant impacts of climate change pushing member states to take quicker action by MEPC 82. He emphasizes the importance of reducing emissions to absolute zero and warns against incremental regulations that may lead to half measures or investments in technologies that could worsen emissions. MacLaine suggests focusing on smaller vessels with simpler operating profiles to support the development and proliferation of absolute zero emission technologies before transitioning larger vessels.

In summary, there is a growing focus on green propulsion in the maritime industry, with hydrogen and battery-electric systems gaining momentum. Fully electric and wind-assisted vessels are proving to be economically viable options. However, stricter regulations and market-based measures are necessary to accelerate the adoption of these technologies. The industry should prioritize absolute zero emission technologies and consider starting with smaller vessels before transitioning larger ones.
