MultHyFuel delivered advances across technical, regulatory and socio-economic domains. Technically, it generated new empirical data on H2 leakage and ignition not previously available. This supports more accurate risk assessments and safer, more efficient HRS designs. Methodologically, the co-creation approach—with stakeholders involved from concept to validation—ensures practical, actionable results.
Regulatorily, the project produced the first EU-wide comparative study of permitting rules for H2 in multi-fuel stations, exposing legal fragmentation and informing calls for harmonisation. This knowledge base empowers national regulators to revise or create evidence-based guidelines.
Socio-economically, the project’s outputs are expected to streamline HRS permitting, reduce administrative uncertainty and accelerate infrastructure rollout. This supports H2 market development, lowers investment barriers and encourages widespread adoption of fuel-cell electric vehicles. It also enhances public safety by defining robust engineering controls, safety zones and mitigation strategies, helping avoid accidents and build public confidence.
Environmentally, the integration of H2 into existing refueling infrastructure enables a faster transition to low-emission transport. By embedding H2 safely alongside other fuels, MultHyFuel supports Europe’s Green Deal goals and the deployment of clean mobility systems.
In summary, MultHyFuel has delivered the tools, data and consensus necessary to standardize H2 safety practices across the EU. Its outputs are poised to shape regulations, influence standards, and facilitate the safe, large-scale adoption of H2 as a key transport fuel.
