"Romm's clear and precise analysis is must reading for anyone who thinks hydrogen cars can help us address global warming before mid-century..."

- Arthur H. Rosenfeld, Commissioner, California Energy Commission

"Romm's book offers a realistic view about the challenges -- the opportunities -- in commercializing hydrogen and fuel cell technologies.  This book is a great investment if you're thinking of putting money, time, or energy into this field."

- John Doerr, Partner, Kleiner Perkins Caufield & Byers

"This provocative book shows why we cannot put all our eggs in the hydrogen basket.  If we do nothing to fix global warming or cut our foreign oil dependence until a hydrogen economy is ready, these problems will be too big to solve."

- John H. Adams, President, Natural Resources Defense Council

"This is an important and opportune book.  Joe Romm deftly applies his keenly developed technical knowledge, political experience, and analytical mind to a frank and sensible appraisal of the chances to transform our energy system over the next half-century or so into one that will employ hydrogen as a key energy carrier."

- from the foreword by John H. Gibbons, former Science Advisor to the President
