Hydrogen is expected to play a key role in the further development and completion of the German energy transition. But what are citizens' attitudes towards this technology? In a meta-study conducted as part of the H2-Wyhlen project, DIALOGIK comparatively evaluated representative surveys on the perception of hydrogen in Germany. The results show a high degree of openness towards hydrogen, which citizens consider to be an environmentally and climate-friendly energy with a low risk potential (working paper available in German only).
