Abstract

Hydrogen technologies and fuel cells evoke, for many people, vision of a future in which electrical energy and heat can be generated not only cleanly but also noiselessly and efficiently—with only water as by-product at the point of use. These technologies—particularly for transport applications—are viewed as a bridge to a sustainable and secure energy future. But despite its clear promise, hydrogen is today still largely only a potential energy carrier of the future; this chemical element is usually a key component of long-term energy policies. But, as recently noted by Eames and McDowall: “…it is expectations about, and visions of, the future of hydrogen that are currently driving investment and research.”

This article explores some of these expectations; in particular, we examine important scientific and technological issues concerning the production, storage, and utilization of hydrogen, as well as outlining the interrelated—and equally challenging—socioeconomic issues for a future hydrogen energy economy. We hope that this approach allows the reader to assess the complexities, challenges—and, of course, the considerable potential—of hydrogen and fuel cells in long-term transport strategies. We illustrate the very considerable central role of chemistry in building innovative solutions to key areas of a future hydrogen energy economy.
