The International Maritime Organization (IMO) has set ambitious targets for the maritime sector, mandating a 40% reduction in carbon intensity by 2030 and striving for net-zero emissions by 2050. To achieve these goals, a transition to scalable green fuels such as green methanol and blue/green ammonia is imperative. Green methanol can be produced from biomass feedstocks or by combining captured CO2 and green hydrogen, while green and blue ammonia offer carbon-free alternatives with higher energy densities. Companies like Clariant are developing smart catalyst technologies to optimize production processes, contributing to global carbon neutrality objectives. However, challenges like infrastructure requirements and investment needs must be overcome for widespread adoption of these green fuels. If successfully scaled and adopted, green methanol and green/blue ammonia could significantly reduce greenhouse gas emissions in the maritime sector, fostering innovation, economic opportunities, and collaboration towards a sustainable future.
