Dutch engineering company Duiker Clean Technologies (Duiker) will pilot its AMMONEX ammonia cracking technology at the Plant One facility in the port of Rotterdam. Plant One is a testing ground for innovative and sustainable process technologies.

AMMONEX produces green hydrogen entirely without CO₂ emissions and has been in development since 2022. The company says the technology is designed to regulate heat with exceptional precision, ensuring a highly stable and energy-efficient process that performs reliably and has a long lifespan.

Says Duiker Managing Director Mark van Welsen, “This agreement marks an important step in the realisation of AMMONEX. The pilot enables us to validate our technology in practice and make a concrete contribution to sustainable hydrogen value chains.”

For Plant One, the pilot project confirms the role of the facility in supporting the energy transition. According to Mark Stoelinga, Director Energy at the Port of Rotterdam Authority, the project demonstrates how innovation and energy imports come together. Quoted in a press statement issued by Duiker, he said: “Projects like AMMONEX are essential for building new sustainable energy value chains, such as the import of green hydrogen. They strengthen the port’s international position and provide an important boost to future energy security, the economy, and employment.”

The AMMONEX project is supported by funding from the European Union (Just Transition Fund), the Demonstration Energy and Climate Innovation (DEI+) subsidy of the Ministry of Climate and Green Growth executed by RVO, and GroenvermogenNL.

The FID for the pilot was taken in early 2025. Test results are expected in 2027.
