As pressure mounts for the shipping industry to decarbonize, ammonia is being highlighted as a viable alternative fuel. With maritime shipping contributing close to a billion tons of greenhouse gases annually, the need for sustainable energy sources is critical. Ammonia is gaining attention for its energy density and potential to transform heavy industries, including shipping. The International Maritime Organization has set a target for zero and near-zero greenhouse gas fuels by 2030 to achieve net-zero emissions by 2050. Ammonia, historically used as a fuel, is now being advanced through cracking technology to be utilized as a carbon-free energy source. Its high energy density and existing infrastructure for production and distribution make it an attractive option for the shipping sector. Ammonia can be integrated into existing vessels, offering a phased approach to transitioning to cleaner energy. The industry is urged to embrace ammonia-to-hydrogen technology and provide training for safe implementation. Collaboration and innovation are emphasized as key to successfully navigating the transition towards a sustainable future.
