SCIENTIFIC AMERICAN FRONTIERS: Hydrogen Hopes
The whole article is very interesting -- Stan Ovshinsky is as amazing guy; but check page 4 for the "solid hydrogen storage".
The trick is that the metal heats up when you charge it with hydrogen, so they were using a water jacket to cool it. I think the metal could be charged with hydrogen in a building (a fueling station) where the heat could be recovered -- and then the expended metal powder could be moved out of the car's tank with a vacuum system, and then the charged metal powder could be moved into the car's tank with the same vacuum system. |
Great article, thank you for let me know.
