MAN Energy Solutions, a German manufacturer, has initiated the 'AmmoniaMot 2' project to develop a four-stroke, medium-speed, dual-fuel ammonia-powered engine for the maritime industry. Ammonia engines, alongside hydrogen and electric technologies, are being explored as alternatives to traditional fossil fuels. Ammonia, known for producing no CO₂ emissions when burned, is gaining popularity in heavy-duty transport and maritime sectors. The project, supported by various institutions and the German Federal Ministry, aims to advance sustainable technologies and contribute to decarbonizing the industry. MAN plans to use ammonia-powered engines in newbuild projects for non-passenger vessels and auxiliary GenSets for larger vessels, with a focus on decarbonization and sustainability. The future of alternative energy solutions lies in diversification, where ammonia, hydrogen, and electric engines each play a vital role. While electric engines have made progress, the adoption of hydrogen and ammonia solutions is crucial for heavier transport. Overcoming challenges related to production, storage, infrastructure, and cost will be essential for the widespread use of these technologies in building a sustainable transportation ecosystem.
