DEKRA receives approval for all key services relating to hydrogen (H2) refueling stations

DEKRA is one of the first testing organizations to receive approval for all key services relating to H2 refueling stations (HRSs). Commissioned by refueling station operators, DEKRA experts can certify a facility’s compliance with all applicable safety standards and the H2 quality they deliver.

In summer 2023, DEKRA was authorized by the CEP to independently test and certify H2 refueling stations in accordance with ISO 19880-1c. This puts DEKRA among the first recognized testing organizations to be authorized by the CEP for this task. DEKRA already has a fixed supply agreement with the Ulm-based Center for Solar Energy and H2 Research Baden-Württemberg (ZSW) for the testingincluding acceptance testingof refueling stations.

Impurities in H2 can damage the fuel cells in vehicles, so the H2 sold at refueling stations in Germany must meet the standards defined in DIN EN 17124, which is required by carmakers. As a new service, DEKRA is also offering the testing and confirmation of H2 quality at the pump. DEKRA already has the first confirmed clients for its testing services to ensure safe refueling in accordance with the International Organization for Standardization (ISO) 19880-1c. DEKRA has fixed supply agreements with the ZSW and the Duisburg-based H2 and Fuel Cell Center to test H2 quality and perform acceptance testing at refueling stations.
