In a major shift that could transform the future of maritime transport, new analysis reveals that ammonia could become the most affordable marine fuel by the late 2030s. For seafarers, shipping companies, and maritime students, this isn't just a technological milestone—it's a sign of what's to come. But what exactly is ammonia fuel? Why is it gaining momentum? And how will it impact the lives of those working at sea?
In this article, we explain the future of ammonia as a marine fuel, and what it means for the global maritime industry—especially for those of us who live and work onboard ships.
What Is Ammonia Fuel?
Ammonia (NH₃) is a compound of nitrogen and hydrogen. While it’s best known as a key ingredient in fertilizers, green ammonia—produced using renewable energy—has emerged as a zero-carbon fuel alternative for shipping.
Why ammonia?
- Carbon-free combustion: Unlike heavy fuel oil or LNG, burning ammonia releases no CO₂.
- Energy-dense: Though not as energy-rich as diesel, ammonia stores more energy per volume than hydrogen.
- Infrastructure potential: It can be stored and transported at relatively low pressure compared to hydrogen.
Why Ammonia Could Be the Cheapest Marine Fuel by 2037
According to a new report by analysts in the energy transition space, ammonia is projected to be the most affordable shipping fuel option by the late 2030s. This is driven by several major trends:
Scale and Investment
Green ammonia production is scaling rapidly, with new plants being built in countries like Saudi Arabia, Australia, and Norway. The more supply grows, the more costs fall.
International Maritime Organization (IMO) Targets
The IMO's 2050 net-zero target is pushing the industry to shift away from fossil fuels. As carbon pricing becomes more common, zero-emission fuels like ammonia will become more economically attractive.
Efficiency in Bunkering and Supply Chains
Ports and shipbuilders are starting to invest in ammonia-ready infrastructure, which lowers long-term costs and makes the transition smoother.
What Are the Risks and Challenges?
While ammonia is carbon-free, it’s not risk-free. Here are some of the concerns:
- Toxicity: Ammonia is hazardous if inhaled or leaked. Handling it onboard requires strict safety measures and proper crew training.
- Corrosiveness: It can corrode certain metals and requires specialized storage tanks.
- Lack of current engine compatibility: Few ships today can run on ammonia, though that’s changing.
Still, the benefits may outweigh the risks—especially when weighed against climate inaction.
What Does This Mean for the Maritime Industry?
The rise of ammonia fuel has implications across the entire maritime value chain:
For Shipowners:
- New builds will increasingly be ammonia-ready.
- Retrofitting options are under development.
- Long-term savings on fuel and carbon tax.
For Seafarers:
- New training requirements will emerge around handling toxic fuels.
- Opportunities to specialize in green ship operations.
- Career advantage for those who understand sustainable maritime technologies.
For Maritime Academies:
- Curricula will need to include alternative fuels.
- Safety modules must evolve to address ammonia handling procedures.
How Can Sailors Prepare?
If you're a sailor or maritime cadet reading this, now is the time to prepare for the ammonia era:
1. Stay updated on fuel trends through sites like Bonnytell and IMO publications.
2. Pursue additional certifications related to alternative fuels and environmental protection.
3. Engage with industry webinars or maritime fuel conferences.
4. Consider specializing in environmental management onboard ships.
Final Thoughts
The road to zero-emissions shipping is being built today—and ammonia could be the highway that gets us there. While the transition won't be without challenges, it also presents a unique opportunity to reimagine maritime careers and vessel operations.
For now, one thing is clear: ammonia isn't just a buzzword—it’s a serious contender for the future of marine fuel
