Hydrogen Economy

One more post from Treehugger: Relevant to all groups interested in alternative energy market arrangements, especially emerging or not-yet-fully commercial design concepts and markets.


At this link is a 9-page conceptual design paper outlining a prospective hydrogen economy: one based primarily on solar and wind power. The paper's authors are Greg Blencoe of Hydrogen Discoveries, Inc. and Dr. James G. Blencoe of the Oak Ridge National Laboratory. The technical underpinnings of the paper are: 1.) a valveless fueling system that uses magnesium hydride to safely store hydrogen inside fuel cell-powered vehicles; and, 2.) Hydrogen Discoveries' piping system, which was designed to overcome the problem of embrittlement and leakage problems that ordinary steel pipes face. The intention is to overcome the "last mile" problems of safely distributing and dispensing hydrogen fuel, and, in this case, of reclaiming and recycling the Magnesium carrier media for continuous re-use.
