Höegh Evi and Nord Gas Solutions validate ammonia-to-hydrogen cracking technology for floating hydrogen terminals
Höegh Evi and Nord Gas Solutions (formerly Wartsila Gas Solutions) have successfully completed performance testing for their ammonia-to-hydrogen cracking technology at the Sustainable Energy pilot plant in Stord, Norway.
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%.
With a modular design optimized for adaptability and scalability, the cracker can be deployed in both floating terminals and land-based applications. Höegh Evi is currently developing cost-competitive floating terminals with the capacity to deliver hydrogen at an industrial scale of up to 200,000 tpy.
"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 global hydrogen production capacity grows, European ports are emerging as a vital gateway where import terminals can receive ammonia and convert it to hydrogen, providing clean, competitive and reliable energy. Together with partners, Höegh Evi is progressing the development of several maritime terminals across Europe, where this highly effective ammonia cracking technology is planned for deployment on a floating terminal or onshore.
The ammonia-to-hydrogen cracking technology development has been financially supported by the Norwegian Green Platform program. In addition to Höegh Evi and Nord Gas Solutions, the consortium includes BASF, contributing for catalyst supply; the University of South-East Norway; Sustainable Energy; and Norwegian Institute for Energy Technology (IFE).
