The pursuit of innovative hydrogen sources is essential for advancing hydrogen energy research. The decomposition of water using metals like aluminum offers a promising route for hydrogen production due to its benefits of high energy density, cost-effectiveness, and environmentally safe products. Despite challenges like oxide film formation hindering the reaction at room temperature, methods like ball milling and alloy addition are being explored to enhance the reaction efficiency. Studies on the Al-water reaction mechanism utilize gas measurement, calorimetry, and kinetic modeling to understand the process intricately. Experimental investigations on micron aluminum powder at low temperatures shed light on the hydrogen production process and morphological changes in the reaction products. By using techniques like DSC and ARC, researchers are determining the exothermic properties of the Al-water reaction, offering valuable insights into temperature conditions and reaction mechanisms. This comprehensive approach aims to overcome challenges and optimize the aluminum-water reaction for efficient hydrogen production, highlighting the potential of this method in the realm of renewable energy.
