The Mirage of Citizen Engagement in Uncertain Science: Public attitudes towards hydrogen energy

This paper addresses some of the debates about citizen involvement in decisions about science and technological innovation. It describes some of the claims and scientific uncertainties surrounding hydrogen energy. It examines qualitative evidence from a series of recent case studies in the UK about public perceptions of hydrogen. It is shown that public attitudes towards citizen engagement are highly ambivalent. While citizens approve of greater consultation, they raise doubts about the degree to which laypersons can be mobilised to participate in public debates, they express contradictory views about their trust in experts, and they are sceptical about whether such involvement will influence policy. These findings add further questions about the efficacy of upstream public engagement in assessments of emergent or novel technologies. They also suggest that over-optimistic expectations about upstream engagement may have to be moderated.
