John Cockerill Hydrogen Secures €116M to Scale Pressurized Alkaline Electrolyzers for Green Hydrogen Expansion

John Cockerill Hydrogen has just wrapped up a major fundraising round, locking in a solid €116 million to push its green hydrogen ambitions even further. Finalized in June 2025, this new capital boost brings onboard Fluxys—Belgium’s hydrogen infrastructure heavyweight—as a fresh strategic shareholder. Existing backers like SFPIM, Wallonie Entreprendre, SLB, and the Rely joint venture also doubled down with renewed investments, showing strong confidence in the road ahead.

Fueling the Future: Why This Raise Matters

Fresh off a €230 million raise in 2024, this latest round is laser-focused on scaling John Cockerill’s signature pressurized alkaline electrolyzer technology. With the global push for industrial decarbonization gaining serious traction, demand for large-scale hydrogen production systems is heating up—especially across Europe and India. The company’s high-output, flexible electrolyzers are key players in powering up production plants that run entirely on renewable energy.

“This funding brings our global rollout one step closer and gives Belgium a strong boost as a hydrogen leader in Europe,” shared a spokesperson from John Cockerill Hydrogen in the official announcement.

Inside the Tech: Pressurized Alkaline Electrolyzers

At the core of their expansion lies John Cockerill’s own pressurized alkaline electrolyzer, which can crank out up to 1,000Nm³ of hydrogen each hour—equivalent to about 5 MW per stack. Using renewable electricity, these systems split water molecules into hydrogen and oxygen under pressure using an alkaline solution. They’re not just efficient—they’re among the most powerful single-stack systems available anywhere in the world.

A Powerhouse Consortium Behind the Mission

The addition of Fluxys is a game-changer. It brings tighter cohesion between hydrogen infrastructure and generation, making rollout smoother and more strategically aligned. Investment heavyweights like SFPIM and Wallonie Entreprendre are doubling down on their commitment to energy security and industrial transformation—especially in the Walloon region. Meanwhile, SLB (formerly Schlumberger) and Rely—backed by Technip Energies—are putting both money and expertise on the table, underlining growing industry confidence in John Cockerill’s green hydrogen game plan.

Belgium’s Hydrogen Backbone and Global Playbook

Belgium is shaping up to be a central player in Europe’s evolving hydrogen economy, and Wallonia is taking the lead within its borders. Thanks to strong public-private collaboration, the country is building a robust and connected hydrogen ecosystem. Fluxys is leading efforts to create a nationwide hydrogen backbone, tying into John Cockerill’s production hubs in Seraing, Belgium, and Aspach, France.

On the international side, the company’s reach is stretching to India, where it’s supplying green hydrogen systems for the country’s largest clean ammonia project through a partnership with AM Green. It’s a clear sign they’re not just exporting tech—they’re exporting impact.

Driving Decarbonization and Economic Momentum

This isn’t just about building more electrolyzers—it’s about transforming entire industries. As sectors like chemicals, steel, and transport turn the page on fossil-based hydrogen, scalable electrolysis is becoming essential. With this expansion, John Cockerill is primed to create local jobs, increase exports, and help build Europe’s long-term industrial independence—especially crucial in today’s uncertain global landscape.

The €116 million raise covers nearly all of John Cockerill Hydrogen’s expected mid-term capital needs. More than just funding, it fast-tracks the roll-out of next-gen electrolyzer systems and gives Belgium a front-row seat in Europe’s green hydrogen push. In a race where cost, scale, and speed matter, this move packs both strategic weight and big-picture significance.

What’s Next

For energy players, industrial partners, or nations eyeing the hydrogen transition, the message is loud and clear: infrastructure matters, partnerships are critical, and advanced electrolyzer tech is no longer niche—it’s the cornerstone. With deep engineering roots and a fast-expanding global reach, John Cockerill Hydrogen is gearing up to help shape a low-carbon future, one megawatt at a time.
