Rely Solutions

What Rely Solutions does

Rely Solutions is a Brussels-headquartered joint venture, established in November 2023 between Technip Energies (60%) and John Cockerill (40%), dedicated to delivering integrated green hydrogen and Power-to-X solutions at industrial scale. The company serves large-scale industrial clients—including green hydrogen producers, green ammonia developers, and sustainable aviation fuel producers—targeting 100MW+ capacity projects across Europe and South Asia, with active references in India (AM Green Kakinada, 1Mtpa), France (H4 Marseille Fos, Verso Energy), and the Netherlands (Power2X Djewels). The asset-light operating model concentrates Rely's value-add on systems integration and engineering rather than asset ownership, drawing on the bench of more than 200 hydrogen specialists inherited from the two parents.

Rely's core offering is the Clear100+ productized plant—a standardized yet configurable 100MW green hydrogen production facility built around John Cockerill Hydrogen's pressurized alkaline electrolyzers and structured as five scalable 20MW blocks. The new generation (launched May 2025) materially reduces equipment count (15% reduction), mutualizes balance-of-plant components (from four SEPAs to one, two PCUs to one), adopts a ground-level PCU architecture for easier assembly and maintenance, and centralizes the electrical and control zone. The technology stack is complemented by plant-level Energy Management Systems, a Rely Technology Center exploring Power-to-X applications (green ammonia, e-methanol, e-SAF, e-methane, hydrogen as reducing agent in steel), and a Joint Innovation Platform with John Cockerill Hydrogen that develops proprietary IP across stacks, BoP, and BoS.

The business monetizes through enterprise field sales, with revenue streams spanning EPC contracts (one-time project license), EPsCm and FEED services (professional services), and recurring Operations & Maintenance engagements and Long-Term Service Agreements with integrated availability, degradation, and stack lifetime guarantees. Beyond private commercial contracts, Rely has signed MOUs with export credit agencies (Bpifrance Assurance Export, Credendo) to support customer project financing, and participates in research collaborations including a three-year AEM electrolyzer program with TNO VoltaChem and Jolt, and the IEA Hydrogen TCP Task 43-C on safety distance methodologies.
