The shipping industry is exploring innovative solutions to reduce CO2 emissions by considering alternative fuels like ammonia. While traditional engine technologies are being optimized, the focus now shifts towards low carbon ammonia gas turbines that promise 100% ammonia combustion, aiming for completion by 2028. Green ammonia production methods are evolving, with MIT's geological process showcasing a promising method that utilizes renewable energy sources. In parallel, companies like Hapag-Lloyd, GTT, and COSCO Shipping are actively investing in ammonia-powered vessels. Hanwha Power Systems, Hanwha Ocean, and Baker Hughes are collaborating to develop these ammonia gas turbines, indicating a collective commitment to decarbonization in the shipping industry. Moreover, Amogy's successful demonstration of a carbon-free, ammonia-powered maritime vessel in 2024 highlights the tangible progress towards sustainable shipping practices.
