Founded in 1889, PRUSS has long been recognised for its specialised expertise in control valves and actuators, with a strong foothold in gas-fired power generation and a growing presence across the hydrogen value chain. In recent years, the Hanover-based company has expanded its product portfolio, machining capabilities, and global footprint, further strengthening its position in the evolving energy sector. We caught up with Wilfried Drehmel, CEO of PRUSS, to learn how the company is navigating a challenging yet opportunity-rich landscape.

Consolidation within the green hydrogen electrolyser development, production, and deployment value chain will snowball through to the end of this decade. At present, weak players are being propped up by subsidies and false hope. Poor ideas with only marginal potential are being hyped up as revolutionary. Consolidation will mean the survival of the fittest. Those with the best technology, the best commercialisation strategy, and the strongest partnerships will make it. Others will either fall by the wayside or be integrated into the winners in one way or another. There will be winners and losers along the way, but the industry will enter the 2030s in much better shape than it is now.

The hydrogen electrolyzer market is undergoing a pivotal transformation, driven by consolidation, financial resilience, and shifting strategic priorities. While 2024 saw high-profile project cancellations and concerns over production overcapacity, 2025 marks a critical phase where commercial execution takes center stage. Guidehouse Insights’ latest Hydrogen Electrolyzer Leaderboard ranks the most prominent vendors based on market strategy and execution. This article examines the evolving vendor landscape, key ranking insights, and the broader implications for green hydrogen’s future.

The global push for decarbonization has positioned green hydrogen as one of key components of the energy transition. However, large-scale deployment remains constrained by high costs, fragmented supply chains, and long project timelines. Addressing these barriers, Rely – a joint venture between Technip Energies and John Cockerill – has introduced an innovative approach that combines standardization, seamless integration, and a fully wrapped project delivery model for green hydrogen and power-to-X. With its flagship product, Clear100+, Rely is transforming how green hydrogen plants are designed, built, and operated, making industrial-scale hydrogen production more efficient, cost-effective, and reliable.
