A system for supplying ammonia as fuel, which can be retrofitted to existing ships or installed on new builds, has received Approval in Principle (AIP) from ABS.
The ammonia fuel supply system from Nikkiso Clean Energy & Industrial Gases, part of Nikkiso Co., Ltd.’s Industrial Division, features high efficiency pumps and an integrated fuel management system. ABS completed design reviews based on class and statutory requirements.
“The ability to retrofit is significant for the maritime industry to meet sustainability objectives. This new fuel supply system promises a solution with decarbonization benefits of alternative fuels like ammonia to be available for existing vessels near-term. Along with safety excellence, our deep technical expertise in alternative fuels and engine designs makes us the ideal classification society for innovative projects such as this from Nikkiso,” said Michael Kei, ABS Vice President, Technology.
As Konstantinos Fakiolas, Director of Marine, Nikkiso Clean Energy & Industrial Gases, explained, Nikkiso’s FSS for ammonia is designed under the principles of redundancy, enhanced reliability and robustness with the highest safety standards for mitigating leakages and slippages.
Ammonia is considered a viable alternative fuel for shipping, especially in the context of reducing greenhouse gas emissions. However, its widespread use comes with several challenges and opportunities. According to a recent report, the use of ammonia as marine fuel in current marine engines shows potential GHG reductions over the entire life cycle from Well-to-Wake (WtW).
Pilot projects are underway, and class societies like ABS are beginning to grant approvals for ammonia-fuel technologies, but it will likely take time before ammonia becomes mainstream in shipping. Widespread adoption will also depend on the development of green ammonia production, regulatory frameworks, and global safety standards.
Lloyd’s Register has identified that by taking steps to develop a framework today, the industry can avoid delays and build on the strong technology case for ammonia adoption.
