Green hydrogen in the Port of Rotterdam moves closer with selection of Enapter’s AEM Nexus 2500
Smart Hydrogen Hub, a collaborative project, brings together public and private partners to demonstrate how green hydrogen production, renewable electricity, energy storage, certification, and local use can be integrated into a single energy system.
From technical discussions to technology selection
This was more than a supplier visit.
Last week, representatives from across the Rotterdam hydrogen ecosystem visited Enapter’s headquarters and production facility in Pisa to explore what it takes to turn green hydrogen projects into reality.
What made this visit different was its focus. The conversations were not about choosing an electrolyzer. They focused on how modular green hydrogen production can be deployed, integrated, certified, financed, connected to industrial offtake, and ultimately scaled within the Port of Rotterdam ecosystem.
Following these discussions, the project partners have announced the next step for Smart Hydrogen Hub.

Rotterdam, July 15, 2026 – Smart Hydrogen Hub has selected Enapter’s AEM Nexus 2500 as the core electrolyzer technology for its planned green hydrogen demonstrator in Rotterdam’s M4H district. The project is being developed in collaboration with Platform Zero, Adsensys and other public and private partners, including the Port of Rotterdam and InnovationQuarter.
The selection represents an important step toward the development of a scalable hydrogen hub that brings renewable electricity, energy storage, hydrogen production, certification and local use together at a single location.
The demonstrator will prove how these components can be integrated and operated as one flexible energy system under real-world port and industrial conditions. It will demonstrate how hydrogen production can respond to variable renewable electricity, how storage and control systems can support efficient operation, and how certified green hydrogen can be supplied reliably to local users.
For industrial, mobility and maritime companies, the hub is intended to provide access to reliable, locally produced green hydrogen in volumes that can grow alongside demand. For technology providers, startups, scale-ups, innovative SMEs, knowledge institutions and public partners, it will provide a practical environment in which technologies, business models and regulatory approaches can be tested and further developed.

The AEM Nexus 2500 is Enapter’s next-generation 2.5 MW Multi-Core electrolyzer for industrial applications. Its modular architecture is designed to support:
- phased expansion and scaling of hydrogen production capacity;
- responsive operation under variable renewable energy conditions; and
- integration into larger hydrogen and energy-management systems.
These characteristics align closely with Smart Hydrogen Hub’s ambition to realize a flexible, replicable and future-proof hydrogen demonstrator in the Port of Rotterdam.
Smart Hydrogen Hub is being developed as a demonstration environment for companies, knowledge institutions and public-sector partners working on industrial electrification, mobility and maritime applications. The hub will combine flexible green hydrogen production with battery storage, locally generated renewable electricity, energy-management systems, certification and connections to local users.
Through this integrated approach, the project aims to accelerate the development of Rotterdam’s hydrogen value chain and support the practical deployment and scaling of green hydrogen.
“Smart Hydrogen Hub is intended to be more than an individual installation. It will be a place where we make the entire hydrogen value chain tangible: from renewable electricity and storage to production, certification and local use. By selecting the AEM Nexus 2500, we are taking an important step toward a scalable energy system that demonstrates how green hydrogen can work in practice in a port and industrial environment,” says Auke Ferwerda, on behalf of Smart Hydrogen Hub.
Enapter sees the collaboration as an important step in the deployment of AEM electrolysis in industrial and port environments.

VP Sales, Enapter“Ports have a central role to play in the emerging hydrogen economy. They bring together energy infrastructure, industry, logistics and international trade flows. Smart Hydrogen Hub will demonstrate how modular AEM electrolysis can operate within this complex environment, where flexibility, scalability and reliability are essential. With the AEM Nexus 2500, we aim to contribute to a practical and replicable model for green hydrogen production in port areas.”

Arthur Scheffer
Founder, Adsensys“The hydrogen market needs projects that progress from planning to execution. We need to start building, learn by doing and develop systems that perform reliably in practice. The selection of the AEM Nexus 2500 gives Smart Hydrogen Hub a clear technological foundation. The next step is to translate that foundation into a safe, robust and operational installation in which electrolysis, energy storage, control systems and connections to hydrogen users are properly integrated.”
