interesting article on hydrogen for starters by Jeremy Rifkin, his latest book is “The Hydrogen Economy”.
Hydrogen: Empowering the People Hydrogen: Empowering the People
In a hydrogen economy the centralized, top-down flow of energy, controlled by global oil companies and utilities, would become obsolete. Instead, millions of end users would connect their fuel cells into local, regional and national hydrogen energy webs (HEWs), using the same design principles and smart technologies that made the World Wide Web possible.
Automobiles with hydrogen cells would be power stations on wheels, each with a generating capacity of 20 kilowatts. Since the average car is parked most of the time, it can be plugged in, during nonuse hours, to the home, office or the main interactive electricity network. Thus, car owners could sell electricity back to the grid. If just 25 percent of all US cars supplied energy to the grid, all the power plants in the country could be eliminated.
