"Green Revolution: Hydrogen" explores hydrogen as a clean energy source and explains how it can store and deliver power for homes, vehicles, and devices. The video introduces key chemistry and physical science concepts, including electrolysis, catalysts, fuel cells, electrodes, membranes, electrons, protons, and chemical reactions. It shows how water can be split into hydrogen and oxygen using electricity, then recombined in a fuel cell to generate electricity with water as the main byproduct. The program also connects renewable energy, sunlight, and energy storage, highlighting hydrogen technology’s importance in environmental science, engineering, and sustainable energy curricula. Part of the "Green Revolution" series.
