In this manuscript we present the results of a four-year monitor among a representative panel of Dutch citizens on the knowledge, awareness and opinions regarding hydrogen. Hydrogen has the potential to play an important role in the energy transition and therefore receives a growing attention. At the start we wanted to know how the Dutch population felt upon hydrogen and its applications. By knowing how the Dutch feel about hydrogen, we could design campaigns to inform the public better and make these campaigns more tailored on the questions or worries the public has regarding hydrogen. In this contribution we present the results of these four studies.
