Topsoe has signed an engineering agreement with Approtium, a leading South Korean industrial supplier of H₂, to deliver its proven ammonia cracking technology, H2RETAKE, converting low-carbon ammonia, also referred to as blue ammonia, back into H₂.

Topsoe will deliver its technology to Approtium’s landmark project in Ulsan, South Korea. The facility is projected to produce 75,000 metric tpy of H₂, which will support South Korea’s growing need for co-firing in the power generation sector. 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 said, "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 said, "Our ultimate goal has been to provide clean H₂ 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."

H2RETAKE is Topsoe’s ammonia cracking technology, designed for the high-efficiency conversion of ammonia into high-purity H₂, with an energy efficiency of 96%. It produces high-quality H₂ suitable for various industrial applications. A unique feature of H2RETAKE™ is its ability to use off-gases as fuel for the endothermic reaction, enhancing its overall efficiency. It can process any commercial-grade ammonia feed source, demonstrating its adaptability in different operational contexts for H₂ production.
