Hydrogen is regarded as a key component of future low-carbon energy systems. Yet, for the implementation of hydrogen technologies on a large scale it is necessary to consider social acceptance. Studies on acceptance of hydrogen technologies have resulted in neutral to positive evaluations. This paper extends previous studies by focusing on large-scale hydrogen infrastructure. Within the project ELEGANCY, quantitative data on the acceptance was gathered among the German population. The results confirm the positive perception of hydrogen on a general level. However, the high level of acceptance is decreasing when it comes to infrastructure implementation in the own neighbourhood. In this paper, the gap between acceptance of hydrogen technology on a general level and the level of its infrastructural implementation is analysed, focusing on new pipeline infrastructure. The results show that sociodemographic factors, especially the variable age, as well as project-related factors, especially trust in stakeholders, have a high explanatory power. • Hydrogen technology is highly accepted in the German population. • Acceptance is decreasing, when it comes to large-scale infrastructure. • Effects of NIMBY are related to project-related, personal and place-based factors. • NIMBYism can be addressed through increasing trust in stakeholders.
