Hydrogen-sentrene for yrkesfaglig fremragende kompetanse (Hydrogen Centers of Vocational Excellence) har som mål å styrke enkeltpersoner og organisasjoner gjennom utvikling av ferdighetene som trengs for å drive frem hydrogensamfunnet. Gjennom samarbeid mellom regioner over hele Europa arbeides det for å skape et levende nettverk av yrkesfaglig fremragende kompetanse, som knytter sammen utdanningsinstitusjoner, næringsliv og lokalsamfunn. Visjonen er å utvikle en kompetent arbeidsstyrke som kan drive innovasjon innen ren energi, og som dermed bidrar til bærekraftig vekst og økt miljømessig motstandsdyktighet.
