Hydrogen storage

Hydrogen storage is like saving energy for later. If you think about a balloon filled with air, the air inside is energy that can be used later. But instead of air, with hydrogen storage, we fill the balloon with hydrogen gas. Hydrogen gas is a special kind of energy, and it can be used in special kinds of engines and machines. So, if we save the hydrogen in a special container, we can use it later and it's like saving energy for later.
