Oceangoing vessels are responsible for about 3% of total greenhouse gas emissions globally, prompting the Port of Seattle to commit to eliminating emissions from seaport-related activities by 2050. While advancements in engine efficiency and emission control technologies can reduce emissions in the short term, a massive shift to next-generation maritime fuels is essential for long-term sustainability. Methanol, among other potential fuels like ammonia and hydrogen, is gaining traction as a leading alternative due to its high energy density and reduced air pollutants during combustion. However, challenges such as flammability, toxicity, and corrosivity need to be addressed through enhanced safety measures. The concept of 'green methanol' involves offsetting emissions during production to achieve a net-zero impact, emphasizing the importance of sustainable feedstocks and renewable energy sources in its manufacturing. Collaboration with regulatory agencies ensures thorough risk assessment and mitigation strategies. While environmental risks from methanol spills exist, research indicates minimal long-term impacts compared to traditional petroleum fuels. The transition to green methanol as a marine fuel presents both opportunities and challenges, with a focus on sustainability, safety, and environmental stewardship.
