Topsoe’s ammonia technology picked for new hydrogen project in South Korea

Danish technology company Topsoe has signed an engineering agreement with the South Korean industrial supplier of hydrogen Approtium to convert low-carbon ammonia into hydrogen using its H2RETAKE technology.

Specifically, Topsoe said the company will deliver its technology to Approtium’s project in Ulsan, South Korea, where the latter plans to build an ammonia cracking plant to produce 75,000 metric tons of low-carbon hydrogen annually.

The plant’s production will start in 2027, Topsoe noted, adding that the project contributes significantly to South Korea’s target of reducing greenhouse gas emissions with 40% in 2030 (2018 as baseline).

Elena Scaltritti, Chief Commercial Officer at Topsoe, commented: “We are excited to embark on this project with Approtium, showcasing not only the potential of our innovative technology but also the strengths of ammonia as a key energy carrier. Greenhouse gas emissions need to be reduced drastically on a global scale and through this project, Topsoe delivers a strong contribution to support South Korea’s decarbonization targets.”

James Kim, CEO of Approtium, stated: “Our ultimate goal has been to provide clean hydrogen to clients and contribute to accelerate carbon neutrality in Korea. This collaboration with Topsoe marks a significant milestone in our relentless pursuit of that goal and signifies our commitment to providing value to both our clients and society.”

To note, according to Topsoe, H2RETAKE, designed for the high-efficiency conversion of ammonia into high-purity hydrogen, with an energy efficiency of 96%, produces high-quality hydrogen suitable for various industrial applications.

Its unique feature is its ability to use off-gases as fuel for the endothermic reaction, enhancing its overall efficiency, Topsoe said, noting that the technology can process any commercial-grade ammonia feed source, demonstrating its adaptability in different operational contexts for hydrogen production.
