We invite researchers, industry practitioners, policymakers, and technology developers to submit abstracts for The H2 Summit 2026, an international forum dedicated to advancing hydrogen as a cornerstone of Europe’s energy transition.
This conference will bring together academic excellence and industrial expertise to explore how hydrogen can strengthen energy and system security, enhance industrial competitiveness and strategic autonomy, and enable digital and data sovereignty in next-generation energy systems.
Authors are encouraged to frame their contributions not only in terms of technical novelty, but also in relation to one or more of the conference’s three strategic dimensions:
- Energy and system security
How does the work strengthen resilience, reliability, flexibility, safety, or infrastructure readiness of hydrogen-based energy systems? - Industrial competitiveness and strategic autonomy
How does the work support cost reduction, manufacturability, supply-chain resilience, scale-up, deployment, or Europe’s industrial leadership in hydrogen? - Digital and data sovereignty
How does the work contribute to digital integration, intelligent operation, trusted data ecosystems, interoperability, cybersecurity, or AI-enabled hydrogen systems?
Submissions focused on materials, catalysts, membranes, electrodes, storage media, reactor design, and other experimental innovations are particularly encouraged to articulate their broader relevance beyond laboratory performance. This may include implications for:
- manufacturability and scale-up,
- critical materials dependence and supply risk,
- safety and lifecycle sustainability,
- industrial deployment pathways,
- integration into infrastructure and energy systems,
- digital monitoring, control, and data-driven optimisation.
Abstracts that connect experimental advances to system, industrial, or digital implications will be especially welcomed.
