The maritime industry, a cornerstone of global trade, faces a critical challenge in reducing its carbon footprint to meet international regulations for carbon intensity reduction and net-zero emissions. The International Maritime Organization's mandates have spurred the industry to explore sustainable fuel alternatives to traditional fossil-based options. Green methanol, derived from biomass or CO2 and green hydrogen, and blue/green ammonia, produced from green hydrogen and nitrogen, emerge as frontrunners in this transition. Despite their environmental benefits, challenges like infrastructure requirements and production optimization remain to be addressed. Catalyst technologies, exemplified by Clariant's innovations, offer solutions to enhance the efficiency and cost-effectiveness of green fuel production processes. The successful implementation of these green fuels in maritime operations not only promises a significant reduction in greenhouse gas emissions but also opens doors to innovation, economic growth, and international collaboration towards achieving global emission reduction goals.
