Revolutionizing the Energy Transition: World’s First Floating Ammonia-to-Hydrogen Cracker
A groundbreaking project launched in 2023 by Höegh Evi and Wärtsilä’s Gas Solutions union has achieved a major milestone by developing the world’s first floating ammonia-to-hydrogen cracker. This innovative technology is set to transform the energy landscape by enabling floating import terminals to produce hydrogen at industrial-scale volumes from transported ammonia, marking a significant step in the energy transition.
Hydrogen has emerged as a crucial energy source, particularly for hard-to-abate industries, with ammonia serving as an efficient carrier of hydrogen. In line with the EU’s REPower strategy, Europe aims to import 10 million tonnes of renewable hydrogen annually by 2030. To meet this growing demand, Höegh Evi and other industry players are spearheading hydrogen import terminal projects in Europe, with operations slated to commence before 2030.
Unlocking Large-Scale Imports with Floating Infrastructure
As the hydrogen grid infrastructure continues to evolve, Höegh Evi envisions that floating infrastructure equipped with ammonia cracking technology can facilitate large-scale imports. Collaborating with Wärtsilä Gas Solutions and participating in Norway’s green platform program, the companies endeavored to develop an efficient platform for cracking ammonia, drawing parallels to existing floating LNG regasification terminals.
“The development of the floating ammonia-to-hydrogen cracker represents a significant advancement in our pursuit of sustainable energy solutions,” stated Walter Reggente, Vice President of Wärtsilä Gas Solutions. “Together with Höegh Evi and our partners, we are not only addressing the challenges of hydrogen storage and transportation but also laying the groundwork for a more resilient and flexible energy infrastructure.”
Industrial-Scale Ammonia Cracker with Modular Design
The industrial-scale ammonia cracker boasts a modular design that allows seamless integration into both hybrid Floating Storage and Regasification Units (FSRUs) and dedicated Floating Hydrogen Terminals. With a sendout capacity of up to 210,000 tonnes of hydrogen annually, the technology is highly scalable. Ammonia storage capacities range from 10,000 cbm to 120,000 cbm, catering to varying needs.
“The floating ammonia-to-hydrogen cracker developed by Höegh Evi, Wärtsilä, and partners heralds a new era for the hydrogen economy and energy transition in Europe,” remarked Erik Nyheim, CEO of Höegh Evi. “Our floating terminals and cracking technology have the potential to unlock global value chains for green hydrogen, offering European industries a reliable supply of clean energy within this decade.”
Funding and Collaborative Efforts
The project received substantial funding amounting to nearly €5.9 million (US$6.7 million) from the Norwegian Government’s green platform program, underscoring the significance of sustainable energy initiatives. The construction of the ammonia cracker took place at Sustainable Energy’s Norwegian Catapult Center in Stord, Norway, with contributions from partners such as the Institute for Energy Technology (IFE), the University of South-East Norway, Sustainable Energy, and BASF SE.
