Fortescue's Green Pioneer, touted as the world's first ammonia dual-powered vessel, embarked on a significant voyage from Singapore, showcasing the use of ammonia in its engines. Dr. Andrew Forest, the Chairman of Fortescue, advocated for global emitters to pay fair carbon prices to drive green investment in the shipping industry during a time when the industry is striving to achieve net-zero greenhouse gas emissions by 2050. Ammonia, sourced from a combination of nitrogen and hydrogen, is positioned as a carbon-free fuel that emits no carbon dioxide when burned, presenting a promising alternative for reducing emissions in shipping. The article delves into the challenges facing the uptake of ammonia, such as toxicity, handling requirements, and storage volumes, and highlights Fortescue's pioneering efforts to address these challenges through projects like the Green Pioneer. Fortescue's ambitious plans to retrofit all its ships with ammonia engines by 2030 and the chartering of ammonia-capable vessels underscore its commitment to decarbonization. The company's innovative approach, including the development of battery energy storage systems and electrolyzer capability for green hydrogen and ammonia production, positions it as a key player in driving sustainability in the shipping industry and beyond.
