The pilot cracker at the Sustainable Energy plant in Stord demonstrated performance across conversion rate, efficiency, hydrogen yield, and operational flexibility. Operating through a single, stable process, the unit converts ammonia into hydrogen at a purity level exceeding 99.5%.

The technology has been designed as a modular system optimized for adaptability and scalability. According to the companies, the cracker can be deployed in floating terminals and land-based applications.

Höegh Evi is developing floating terminals with the capacity to deliver hydrogen at an industrial scale of up to 200,000 tonnes per year. Nord Gas Solutions, formerly Wärtsilä Gas Solutions, has worked with Höegh Evi on the ammonia-to-hydrogen cracking technology.

The technology development has received financial support from the Norwegian Green Platform programme. The consortium also includes BASF for catalyst supply, the University of South-East Norway, Sustainable Energy, and the Norwegian Institute for Energy Technology (IFE).

“Höegh Evi is very pleased with the testing results of our ammonia-to-hydrogen cracker, which has demonstrated high performance, stability and efficient conversion from ammonia to hydrogen. This milestone further confirms the case for floating terminals as a fast and competitive path to implementing hydrogen at scale. We look forward to validating these results further in long-term testing,” said Nils Jakob Hasle, EVP Clean Energy of Höegh Evi.

“This successful testing phase marks an important milestone in validating ammonia cracking as a reliable and scalable pathway to hydrogen. The results confirm both the efficiency and operational robustness of our technology, supporting its readiness for deployment in industrial-scale applications,” said Taro Mukae, VP Technology of Nord Gas Solutions.

As hydrogen production capacity grows, Höegh Evi and its partners are progressing several maritime terminals across Europe where the ammonia cracking technology is planned for deployment on floating terminals or onshore.
