Höegh Evi and gas value chain systems specialist Nord Gas Solutions have finalized performance testing for their advanced ammonia-to-hydrogen cracking technology. The evaluation was conducted at the Sustainable Energy pilot facility in Stord, Norway, marks a key step in the commercial maturation of large-scale hydrogen import infrastructure.
The pilot cracker demonstrated high performance across a range of critical parameters including 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 percent.
Featuring a modular engineering architecture tailored for flexibility and rapid deployment, the cracking system can be deployed in both floating maritime terminals and onshore facilities. Leveraging this capability, Höegh Evi is actively designing cost-competitive floating storage, regasification, and cracking terminals capable of supplying up to 200,000 tonnes of industrial-grade hydrogen per year.

“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 at 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 at Nord Gas Solutions.
As international clean energy networks expand, European ports are becoming vital gateways where dedicated import terminals can process ammonia shipments and convert them into hydrogen to deliver reliable, price-competitive clean energy. In coordination with its project allies, Höegh Evi is advancing the development of several maritime terminals across Europe, with plans to deploy this highly effective cracking technology on floating or land-based structures.
The development of this hydrogen cracking technology was supported by funding from the Norwegian Green Platform program. Beyond Höegh Evi and Nord Gas Solutions, the industrial and academic research consortium includes global chemical company BASF, which supplied the specialized catalyst technologies, the University of South-Eastern Norway, Sustainable Energy, and the Norwegian Institute for Energy Technology (IFE).
