Hydrogen Highways: Lessons on the Energy Technology-Policy Interface

Bulletin of Science, Technology & Society Vol. 26, No. 4, August 2006, 288-298 DOI: 10.1177/0270467606291834 Copyright © 2006 Sage Publications The hydrogen economy has received increasing attention recently. Common reasons cited for investigating hydrogen energy options are improved energy security, reduced environmental impacts, and its contribution to a transition to sustainable energy sources. In anticipation of these benefits, national and local initiatives have been launched in the United States, creating pilot “roadmaps” and technology partnerships to explore hydrogen economy platforms. Although hydrogen can provide several positive improvements over a carbonor uranium-based energy system, several problems are also likely. As well, competitive technologies (e.g., hybrid vehicles) may offer comparatively greater economic and/or environmental advantages. Before policies to advance a hydrogen energy economy proceed, it is vital that all aspects of hydrogen be compared with other available alternatives. Important questions to ask in this regard are whether a hydrogen economy can fulfill key energy needs and whether there are appropriate roles for hydrogen to play in a sustainable energy future.
