On 14–15 October 2025 the partners of the TRIĒRĒS Hydrogen Valley project met in Groningen (Netherlands) for their second General Assembly. The meeting combined technical visits to regional hydrogen infrastructure with strategic discussions on project progress and future implementation steps.
The event was hosted by the New Energy Coalition and Hydrogen Architects and included exchanges with stakeholders from the Dutch hydrogen ecosystem connected to the HEAVENN hydrogen valley initiative.
Situation
The TRIĒRĒS project aims to establish integrated hydrogen value chains linking production, transport infrastructure and industrial demand across regional and European contexts. Such project environments act as coordination platforms where infrastructure development, investment planning and regulatory frameworks evolve simultaneously.
Within this framework, General Assembly meetings provide an opportunity to align project progress with developments in regional hydrogen ecosystems and infrastructure planning initiatives.
Observation in the Living Lab
From the perspective of the Green Energy Center Living Lab, the meeting demonstrates how regional hydrogen ecosystems organise practical infrastructure development through collaboration between infrastructure operators, industry partners and regional innovation networks.
Discussions addressed the development of hydrogen infrastructure corridors, investment frameworks and the connection between regional hydrogen valleys and broader European infrastructure initiatives such as the European Hydrogen Backbone.
Systemic Context
Hydrogen valleys represent experimental infrastructure environments within the broader process of Energy System Reconstruction in Europe. They connect production capacities, transport infrastructure and industrial demand into coordinated value chains that extend beyond individual projects.
The interaction between regional hydrogen ecosystems and emerging European infrastructure corridors illustrates how infrastructure transformation takes place through interconnected regional initiatives rather than through isolated technological deployment.
Relevance for Energy System Reconstruction
For the Green Energy Center Living Lab such project environments provide practical reference points for observing how infrastructure planning, industrial demand and policy frameworks converge in the reconstruction of the European energy system.
The TRIĒRĒS General Assembly therefore represents a coordination moment within a broader infrastructure development landscape linking regional hydrogen initiatives across Europe.
Conclusion
The meeting in Groningen highlights how hydrogen valley initiatives function as operational environments for infrastructure development and system integration within the ongoing reconstruction of the European energy system.
