Germany’s partnership between Uniper and thyssenkrupp Uhde pioneers commercial-scale ammonia cracking, enabling scalable green hydrogen production to decarbonise heavy industries across Europe and strengthen energy security.
In the evolving landscape of industrial decarbonisation, Germany is establishing itself as a pioneering hub for ammonia cracking technology, a critical pathway for delivering clean hydrogen at scale. This advancement is spearheaded by a strategic partnership between energy player Uniper and engineering specialist thyssenkrupp Uhde, targeting the decarbonisation of heavy industries across the country and Europe.
The partnership marks a significant leap in the practical commercialisation of ammonia cracking, a process whereby ammonia (NH3) is converted back into hydrogen gas (H2) and nitrogen (N2). While ammonia has long been used as a hydrogen carrier due to its ease of liquefaction and transport, cracking it efficiently at industrial scales has presented challenges. Thyssenkrupp Uhde’s engineers have developed advanced metal catalysts and reactor designs achieving conversion efficiencies surpassing 90%, materialising this technology from theoretical interest into operational reality.
A landmark pilot plant in Gelsenkirchen-Scholven, situated in Germany’s Ruhr industrial heartland that once thrived on coal and steel production, is now a live laboratory for this clean energy innovation. The 28-tonne-per-day demonstration unit at Uniper’s power station, backed by regional government funding from North Rhine-Westphalia, validates the process and operational concepts under real-world conditions. Here, the liquid ammonia undergoes vapour phase purification before high-temperature catalytic cracking, followed by pressure-swing adsorption to produce hydrogen at 99.9% purity, making it suitable for demanding industrial applications. Crucially, the system recycles most of its heat, enhancing energy efficiency and economic viability.
Building on this success, the partners inked a framework agreement in November 2025 to deploy up to six commercial-scale cracking plants across Germany, with a combined capacity to process 7,200 tonnes of ammonia daily. These facilities will support hydrogen supply to pivotal sectors such as steel production, refineries, and chemical manufacturing, industries essential both to the German economy and the broader European landscape. The first large-scale installation is planned to co-locate with Uniper’s hydrogen import terminal in Wilhelmshaven, a strategic North Sea port transitioning from fossil fuel exports to green energy logistics. Engineering, modular reactor production, catalyst supply, and advanced digital control systems for real-time operations will be jointly managed, ensuring seamless integration and operational flexibility.
This initiative dovetails with the broader European imperative to enhance energy security by diversifying hydrogen supply routes beyond domestic electrolyser capacity, which currently cannot meet industrial demand. Ammonia imported from renewable hydrogen production hubs, ranging from North African solar farms to Scandinavian wind parks, can thus be efficiently converted to hydrogen near consumption points, mitigating supply chain risks and geopolitical uncertainties.
Uniper’s COO Holger Kreetz highlights the crucial role of imports in meeting Germany’s hydrogen needs, framing this partnership as a milestone for the burgeoning hydrogen economy. Meanwhile, North Rhine-Westphalia’s minister for economic affairs, Mona Neubaur, underscores how ammonia cracking extends the reach of green energy worldwide while reinforcing sustainable industrial competitiveness locally.
The vision emerging from this collaboration points to a future where hydrogen, transported and processed via ammonia cracking infrastructure, fuels heavy industry across Europe reliably and cost-effectively. The planned expansion aligns with governmental decarbonisation targets and offers a scalable template for integrating novel hydrogen supply chains into existing industrial ecosystems.
While still in its early commercial phase, the success of this joint venture could galvanise broader market confidence in ammonia cracking as a cornerstone technology for the hydrogen transition. Its implications stretch beyond Germany’s borders, potentially catalysing cross-border hydrogen trading networks and pipeline infrastructure that integrate global renewable energy resources.
For professionals engaged in industrial decarbonisation, the Uniper-thyssenkrupp initiative exemplifies the type of strategic, technology-driven partnerships necessary to tackle emissions from energy-intensive sectors. By advancing ammonia cracking from pilot demonstration to full industrial adoption, they are not only addressing immediate supply challenges but also shaping the infrastructural backbone of tomorrow’s clean industrial economy.
