Future energy is our most serious concern. Hydrogen will be part of the energy mix, but a part that is complicated, expensive, and contentious. Mark Glucina and Kozo Mayumi have scoured and synthesized the literature to produce a primer on hydrogen that ranges from molecules to dollars, the media, and politics. Have a question on hydrogen? You will probably find the answer in Hydrogen Energy in a Sustainable Future: Phantom or Panacea? Beyond technical excellence, the authors have written a book that is accessible, readable, and even enjoyable. This is a book that is both authoritative and pleasant. It is highly recommended.
