Current Market Landscape and Future Trends in Alternative Fuels Impact on U.S. Ports

The maritime industry is shifting towards cleaner energy, with U.S. ports preparing for alternative fuels like ammonia, hydrogen, methanol, and ethanol. While these fuels support environmental goals, they bring unique risks—such as toxicity and flammability—that ports must address. Research led by DHS and partners is assessing port readiness and hazards, with key findings guiding strategies for safer adoption. This work aligns with global efforts for zero-emission shipping by 2050, ensuring resilience while embracing innovation.
