Brooklyn-based Amogy and Osaka-based Yanmar have joined forces to combat climate change by developing power plants for ships using advanced technology to create hydrogen fuel. The collaboration aims to meet the International Maritime Organization's stringent emission reduction targets set for 2030. However, concerns linger about the timely availability of a commercially viable reformer-engine unit to meet the industry's deadlines. John Prousalidis, an expert in naval architecture, stresses the importance of caution in adopting new technologies like ammonia as a primary fuel source due to potential technical challenges and past delays in similar transitions. Despite the optimism that alternative fuels will eventually replace diesel, challenges such as operational failures and logistics readiness pose significant hurdles. The industry is no stranger to ambitious announcements, with past delays in the adoption of new fuels for maritime propulsion. While the transition to alternative fuels is seen as inevitable, the journey is expected to be gradual, resembling the introduction of natural gas in the industry. Researchers highlight the need for comprehensive technical details and stringent testing to ensure the feasibility and safety of implementing such innovative technologies in the maritime sector.
