Cover Story: The hydrogen economy is a potential option for enabling deep decarbonization for the future energy landscape. However, progress towards an operating hydrogen economy has seemed slow despite global efforts to accelerate it. This study uses bibliometric analysis and content analysis to understand whether there has been significant real progress in achieving a hydrogen economy, or whether the current interest is overly exaggerated (hype). Findings indicate that interest in the hydrogen economy has indeed progressed based on the growing number of academic publications, media coverage, and projects. However, various endogenous and exogenous factors have influenced the development of the hydrogen economy and created hype at certain points in time. View this paper
