Hydrogen is a super powerful energy carrier that can be stored and moved around easily. It's produced by splitting water into hydrogen and oxygen using electricity. Storing hydrogen as a compressed gas or a liquid is the best way for practical use. When hydrogen combines with oxygen in a fuel cell, it creates electricity. This method is compared to other energy storage systems, showing how efficient it is. Different ways of making hydrogen through water splitting, storing it, and using it in fuel cells are discussed. Hydrogen looks really promising for storing energy and could lead to an economy fueled by hydrogen.
