We don’t just react – we anticipate. The need for green hydrogen isn’t just a vision – it’s an undeniable reality. As a result, the expectations for service, uptime, and operational efficiency are rising fast. We sat down with Gabor Müller, Senior Service Manager at thyssenkrupp nucera, to explore how his team is shaping the future of service in electrolysis – and why digital tools are key to staying ahead.

What does 360° service mean in the context of thyssenkrupp nucera’s electrolyzer technology?
Service is not a side note but a strategic pillar. Our customers invest in scalable, future-proof technology, and we make sure that this technology performs efficiently over the long term. Service is embedded from day one: It begins right after plant startup and handover. We offer preventive maintenance, digital monitoring, spare parts management, and full service for refurbishment campaigns. Our portfolio includes solutions like nucera care, nucera supply, and digital platforms such as nucera mirror and nucera navigator. This is designed to minimize downtime and extend plant lifespan.
Can you share an example of how digital service tools are used in practice?
Absolutely. At a customer site, we detected a gradual deviation in performance in a cell rack using nucera evaluator. Without this tool, the issue would have only surfaced after a significant drop in output. Thanks to early detection, we were able to intervene proactively without interrupting production.
How does sustainability factor into thyssenkrupp nucera’s service strategy?
Refurbishment is a great example. Instead of replacing components, we restore them to their original performance level. This saves resources by reusing components and reduces CO₂ emissions by reducing overall material use, minimizing waste and emissions. Our digital tools also contribute by reducing travel, enabling more efficient maintenance, and optimizing operations.
What personally motivates you in your role?
I see myself as part of the energy transition. It’s incredibly rewarding to know that our work helps green hydrogen plants operate reliably across the globe, accelerating the eco-friendly practices. We’re not just maintaining systems – we’re enabling real change.
