Hydrazine has been extensively used as one of fuel for spacecraft and satellite propulsion. However, hydrazine is toxic to human body and global environment. Therefore, the fuel for space plane needs the non-toxic clean fuel. Hydrogen has been extensively used as fuel for spacecraft propulsion system, which is environmentally friendly fuel. Hydrogen is generally produced by steam reforming of fossil fuels, but carbon dioxide (CO2) is formed as by-product which causes global warming. We have been investigating the development of new hydrogen production by using aluminum with water. Hydrogen production by aluminum with water forms only hydrogen and aluminum hydroxide. In this study, we investigated the control method in the production of hydrogen using Al-Zn alloy powder by changing the reaction temperature, the size effect of Al powder on high pressure hydrogen production ability, the optimal condition of hydrogen production using the Al-Zn alloy and the application of Al-water reaction in propulsion system of the spacecraft.
