I have a short segment in this week's "Inside Renewable Energy" podcast, about a Seattle company called Hydrogen Power that produces hydrogen from aluminum powder. Their plans for commercialization are quite interesting.

My report (excerpt) is part of a larger story by podcaster Stephen Lacey on how the process works, including an interview with a Purdue University researcher.

Hydrogen isn't renewable energy per se, rather it's a currency in which energy can be saved and transferred. Aluminum processing is energy intensive, but hydrogen allows a clean energy source to provide electricity to areas not connected to it by wires.
