Making Clean Hydrogen Fuel Using Aluminum and Water

2021-9-1 · Another method for producing hydrogen comes from an unexpected source: reacting aluminum with water. But grinding is a costly and energy-intensive process. Magnesium silicide is formed when silicon and magnesium chemically bond to form magnesium silicide, which appears as solid deposits on the internal grain surfaces.
