The global shipping industry is undergoing a transformation to reduce its environmental impact and carbon emissions. With the emergence of innovative technologies, such as liquid natural gas (LNG) and hydrogen-powered ships, the sector is striving to achieve sustainability. In response to the industry's significant contribution to global greenhouse gas emissions and air pollution, various initiatives and regulations have been put in place. The International Maritime Organization (IMO) aims to cut emissions by 40% by 2030 and has implemented measures like fuel consumption data collection and restrictions on high-sulphur fuels. While LNG is currently a prevalent choice due to its lower carbon intensity compared to heavy oils, the industry is also exploring the potential of green hydrogen and ammonia as cleaner alternatives. Despite challenges such as storage requirements and economic feasibility, these options hold promise for the future of maritime transportation. Recent developments include the introduction of battery-powered container ships and projects like the SeaShuttle initiative, which aims to establish zero-emission 'green corridors' using hydrogen-powered ships. These advancements signify a positive shift towards sustainable maritime transportation, with a focus on reducing carbon dioxide emissions and creating environmentally friendly shipping routes.
