The global maritime industry, accounting for 3% of total greenhouse gas emissions, is at a critical juncture in achieving net-zero emissions by 2050. To meet the International Maritime Organization's targets, clean fuels like hydrogen need to represent a significant portion of energy usage by 2030. While hydrogen shows promise for vessels with specific operational needs, economic challenges persist due to high production costs and limited availability of green hydrogen. However, projections suggest that by 2030, producing green hydrogen could be cost-competitive with grey hydrogen in key economies. Governments are stepping in with policies and initiatives to support the adoption of green hydrogen. Infrastructure remains a key hurdle, with maritime operators hesitant to adopt hydrogen without the necessary support. European ports like Rotterdam and Antwerp are spearheading hydrogen infrastructure projects to pave the way for adoption. Initiatives like Norway's HyInfra project and collaborations with companies like Northern XPlorer are exploring the potential of hydrogen and ammonia in maritime applications. Safety concerns around hydrogen flammability are being addressed through the development of international standards, with organizations like Bureau Veritas leading the way. Progress is evident in storage technology and hybrid systems that combine current infrastructure with hydrogen solutions. Partnerships between the public and private sectors are reducing investment risks and demonstrating the feasibility of hydrogen integration in maritime operations. Despite challenges, the maritime industry is evolving to embrace hydrogen for a cleaner and sustainable future.
