Several researchers in commercial, government, and academic realms are studying the possibility of using aluminum as an energy source for vehicles and even grid power. In the commercial realm, Alchemy Research in Israel makes the following rather startling claims. “Alydro is a new technology developed by Alchemy Research for producing clean energy from a reaction of aluminum and water at elevated temperatures. “Alydro generates energy in the form of hydrogen and heat. The only by-product is fully recyclable aluminum oxide. “Alydro is competitive with gasoline on energy density and affordability. It is superior to gasoline on sustainability, environmental characteristics and safety.” Alchemy Research claims that aluminum has 2.5 times the energy density of gasoline, about 84 mega Joules per liter or 23.3 kilowatt hours. Aluminum has about 8.6 kilowatt hours per kilogram, considerably more energy dense than lithium batteries, which range from 120 to 190 Watt-hours per kilogram. Storage takes less space than its equivalent in gasoline and the material is perfectly …
