Zero-carbon ammonia, touted as a promising marine fuel to help the shipping industry cut emissions, is facing notable cost and safety challenges. With the shipping sector responsible for around 3% of global greenhouse gas emissions, ammonia could be a game-changer—especially if produced from renewable hydrogen. However, the practical deployment of ammonia as fuel is complicated by its toxicity, high production costs, and the need for specialized handling protocols.
Key Challenges in Adopting Ammonia as Marine Fuel
1. Safety Concerns
While ammonia is carbon-free when derived from renewable energy sources, it poses significant safety risks. Its toxicity can cause severe health risks to humans, and the potential for leaks makes it dangerous to handle and store on vessels. Current maritime regulations and safety standards are underdeveloped for ammonia use, requiring the International Maritime Organization (IMO) and other regulatory bodies to establish comprehensive safety protocols. Until rigorous safety measures are in place, shipowners remain cautious about adopting ammonia fuel, especially given the liability concerns tied to accidents or exposure incidents.
2. High Production and Fuel Costs
The cost of producing zero-carbon ammonia is substantially higher than traditional marine fuels. Green ammonia production requires large amounts of renewable hydrogen, which itself is costly to produce. Additionally, the infrastructure to store and transport ammonia is still in its infancy, adding further costs. While demand for cleaner fuels is growing, the financial burden of switching to ammonia remains prohibitive for many shipping companies, creating a gap between industry aspirations and economic feasibility.
3. Handling and Bunkering Challenges
Ammonia requires specialized bunkering facilities and equipment due to its hazardous nature. Unlike traditional marine fuels, ammonia cannot be easily stored or transported without rigorous containment measures. Ports and refueling stations need extensive modifications to safely handle ammonia, an investment that few facilities are currently prepared to undertake. Until bunkering infrastructure catches up, ammonia’s role as a mainstream shipping fuel will be limited.
Future Outlook and Potential
Despite these challenges, ammonia has significant long-term potential. Industry experts predict that with continued investment in safety protocols and cost-reduction technologies, ammonia could account for up to a third of marine fuels by 2050. Research and pilot projects are underway to address the production and storage issues, with some companies exploring hybrid solutions that combine ammonia with other low-emission fuels to mitigate risk. For shipowners, the future may hold a phased approach to ammonia adoption, balancing initial safety and cost concerns with the drive to meet stringent emissions targets.
