it's merely an energy storage medium. You can't mine hydrogen, you can't capture it; you have to make it by using more energy than it will deliver.

Sounds like you've just described the model for the battery in an electric car!
But technically we don't "make" hydrogen. We can use chemical reactions or electrolysis to collect it from the earth. An easy way is to pull it out of water molecules. Think of it as mining on a molecular scale. We "mine" a lot of elements out of common molecules this way, including some metals.
