Success of Hydrogen Blending Trials Across Europe Including Netherlands, Portugal, and Germany
Several hydrogen blend trials are underway in Europe, with significant projects in the Netherlands, Portugal, and Germany. The European Clean Hydrogen Alliance, formed in 2020, released a report in April 2025 detailing these efforts. Notable initiatives include the 'Hydrogen City' project in the Netherlands, a 12% hydrogen blend project by Floene in Portugal, and a 100% hydrogen supply trial in Bavaria, Germany. These projects aim to integrate hydrogen into existing gas infrastructure, with goals set for completion by 2030.

Hydrogen blending trials are being conducted across Europe, including the Netherlands, Portugal, and Germany. The European Clean Hydrogen Alliance published a report in April 2025 that outlines these initiatives.
In the Netherlands, the 'Hydrogen City' project aims to replace natural gas with green hydrogen by 2030, repurposing existing infrastructure. Portugal’s Floene is implementing a 12% green hydrogen blend project in Seixal, targeting a 15% blend by 2030.
Meanwhile, in Bavaria, Germany, the H2Direkt project has been supplying 100% hydrogen to households since 2023, with infrastructure reliability confirmed even at -15°C. These projects underscore hydrogen's potential role in the energy transition.
