Manufacturing of hydrogen on demand using aluminum can scrap with near zero waste

Abstract

During the 1990s Powerball Industries, UT had demonstrated producing Hydrogen on demand machinery—where encapsulated sodium metal is reacted with water to release hydrogen gas under pressure. The hydrogen on demand has several applications. Here we discuss the ongoing research of making use of aluminum (recycled or newly produced) with anhydrous sodium sulfate—which will make sodium metal, sulfur oxides, and aluminum oxide. The thermodynamic analysis shows suitable physicochemical conditions for the reactions. Preliminary economics using aluminum scrap—recycled aluminum is shown.
