Tomorrow's Energy: Hydrogen, Fuel Cells, and the Prospects for a Cleaner Planet

The word hydrogen conjures images of devastating bombs and burning zeppelins (the Hindenburg) for most of us, but it inspires visionaries like Peter Hoffmann to picture clear skies and safer roads. Hoffmann's book Tomorrow's Energy traces the history of the volatile gas and explores options for its use as fuel. Though the author can't avoid using some technical language, his writing should still appeal well beyond the community of automotive and power-plant engineers. His coverage, though fairly balanced, tends toward the positive efforts made by government, corporations, environmentalists, and scientists to promote hydrogen as a clean, relatively safe, and potentially cheap alternative to carbon-heavy fuels.

Party-line Greens may gasp at some of the suggested schemes, which include using limited nuclear power to generate hydrogen from water. But Hoffmann convincingly assures the reader that ultimately, the planet will be better off this way. Many will be surprised at how far hydrogen has advanced since serious research restarted during the 1970s fuel crisis: the range of cars, planes, and power networks using the gas for power storage is impressive and underreported.

Though he makes his case for hydrogen as a means of powering our lives, Hoffmann also shows off its uses in medicine, agriculture, metallurgy, and other fields. Using economic data, he shows that we can expect to live in a hydrogen economy sometime midcentury; if so, we can all breathe a collective, CO2-laden sigh of relief. --Rob Lightner
