Abstract

Exemplary embodiments of methods and systems for hydrogen production using an electro-activated material are provided. In some exemplary embodiments, carbon can be electro-activated and used in a chemical reaction with water and a fuel, such as aluminum, to generate hydrogen, where the by-products are electro-activated carbon, and aluminum oxide or aluminum hydroxide. Controlling the temperature of the reaction, and the amounts of aluminum and electro-activated carbon can provide hydrogen on demand at a desired rate of hydrogen generation.

Claims
