John Cockerill advances electrolyzer production following McPhy acquisition

This article was originally posted on Chemical Engineering Online.

Summary
One year after acquiring McPhy’s strategic assets, John Cockerill Hydrogen has hit a key industrial milestone: in Belfort, France, it produced its first on-site assembled electrolysis stack on a new, innovative production line, while in Aspach it is starting a 40 MW production phase for a green hydrogen project—signaling a rapid scale-up of European electrolyzer manufacturing.

What impact could localized stack assembly and a 40 MW build-out have on green hydrogen costs, supply chain resilience, and deployment timelines in Europe?

One year after acquiring McPhy’s strategic assets, John Cockerill Hydrogen (Seraing, Belgium) has reached a new milestone in its industrial development. In Belfort, France, teams have produced the first electrolysis stack assembled on-site using an innovative production line. Meanwhile, in Aspach, a new 40 MW production phase is beginning for a green hydrogen project in […]

What did the “innovative production line” actually automate in stack build - plate alignment/compression, gasket placement verification, in-line leak testing, torque traceability - and how did that change takt time and first-pass yield vs pre-acquisition builds? When we ramped a similar precision stack, seal verification and end-of-line conditioning became the hidden bottlenecks; did you size buffers and wet-test capacity to keep final pack-out from starving?

For the Aspach 40 MW phase, how are you handling grid integration - flexible operation to absorb renewable curtailment and provide primary frequency response, or baseload under firm PPAs? Also curious about the AC/DC front end: active-front-end rectifiers and harmonic mitigation to meet IEEE 519, and whether you interconnected at distribution or transmission to avoid protection and transformer upgrade headaches.
