Where'e the hydrogen economy?

The Honda FCX Clarity

Whatever happened to the hydrogen economy? That's a question NewScientist is addressing today.

Essentially, New Scientist finds, as have many, that the high costs of platinum probably require a replacement for platinum. Clean, efficient production of hydrogen is still, despite some interesting developments in electrolysis, impossible. Basically, the same things that hampered the hydrogen highway 10 years ago, or still hampering the hydrogen highway today.

Yet, some of the world's smartest automakers, especially Honda, continue to believe that the hydrogen economy is just around the corner.
