The electrolyzers market is moving beyond pilot projects and into large-scale industrial deployment, driven by secure access to renewable electricity. A clear example of this shift is Shell’s REFHYNE 2 projects in Germany, where long-term renewable power purchase agreements are being used to support a 100 MW hydrogen electrolyser. This development reflects how energy majors are addressing cost, reliability, and emissions challenges while advancing renewable hydrogen production across Europe.
What Is Driving New Momentum in the Electrolyzers Market in Europe?
The electrolyzers market is gaining momentum due to the growing need for predictable, low-carbon electricity supply to support hydrogen production at scale. In November 2025, Shell Energy Europe Limited signed two power purchase agreements in Germany to supply renewable electricity to the REFHYNE 2 electrolyser currently under construction at the Shell Energy and Chemicals Park Rheinland.
Power supply overview
| Project | Technology | Capacity | Share Off taken by Shell |
| Nordsee One | Offshore wind | 332 MW | ~33% |
| Halenbeck-Rohlsdorf | Solar PV | 230 MW | ~75% |
Why Is the 100 MW REFHYNE 2 Electrolyser Significant for the Electrolyzers Market?
REFHYNE 2 represents a decisive scale-up in electrolyser deployment, moving well beyond earlier demonstration-level projects. In 2024, Shell took a Final Investment Decision to advance the 100 MW proton exchange membrane electrolyser at the Shell Energy and Chemicals Park Rheinland.
Once operational, the facility is expected to produce up to 16,000 tonnes of renewable hydrogen per year, positioning it among the largest renewable hydrogen electrolysers currently under development in Europe.
What Role Do Policy and Funding Play in Scaling the Electrolyzers Market?
REFHYNE 2 has been enabled by supportive European and German policy frameworks, including binding European Union targets for renewable hydrogen use. The project also received funding from the European Union’s Horizon 2020 research and innovation programme.
What Are the Next Steps for Stakeholders in the Electrolyzers Market?
- Secure long-term renewable electricity through PPAs early in project planning.
- Align electrolyser projects with European Union renewable hydrogen regulations.
- Scale capacity incrementally using operational lessons from smaller plants.
- Leverage public funding programmes to reduce early-stage risk.
- Integrate hydrogen use directly into industrial operations for measurable emissions impact.
Conclusion: The REFHYNE 2 project demonstrates how the electrolyzers market is shifting toward execution at scale. By combining long-term renewable power agreements, supportive policy frameworks, and industrial integration, Shell is addressing the structural challenges that have historically limited hydrogen deployment. This approach signals a more mature phase for electrolyser projects in Europe, where scale, reliability, and emissions reduction are converging into viable commercial models.
