Amogy, a pioneer in ammonia-to-power solutions, has successfully demonstrated the world’s first carbon-free, ammonia-powered maritime vessel. The NH3 Kraken, a retrofitted 1957 tugboat, completed its maiden voyage on a tributary of the Hudson River, marking a significant milestone in the maritime industry’s journey towards sustainability.
This groundbreaking achievement brings the industry closer to meeting the International Maritime Organization’s (IMO) target of net-zero emissions by 2050, and proves the viability of Amogy’s technology and highlights ammonia’s potential as a carbon-free maritime fuel.
“Our successful demonstration of the world’s first carbon-free, ammonia-powered vessel proves that [reducing global carbon emissions] is achievable,” said Seonghoon Woo, CEO and co-founder of Amogy. “By demonstrating our technology on the water for the first time, we’ve gained invaluable knowledge that will help us move quickly to commercialization and real-world applications.”
Amogy’s patented technology splits liquid ammonia into hydrogen and nitrogen, with the hydrogen then used in a fuel cell to generate power without carbon emissions. The NH3 Kraken was fueled with green ammonia, produced entirely with renewable energy, further reducing its environmental impact.
With the global shipping industry emitting nearly 1 billion tons of greenhouse gases annually, this successful voyage demonstrates ammonia’s potential to transform the shipping industry and other power generation sectors.
Amogy plans to release a detailed case study in the coming months, providing further insights into its technology. The company says it will apply knowledge gained from this demonstration to real-world applications, including both retrofit projects and newbuilds. The company is already working on contracts signed and in progress with organizations such as Hanwha Ocean, Terox, and others.
