Interesting development - Hydrogen

From Popular Mechanics:

Ditching Platinum for the Ocean Could Make Hydrogen Cheap
Hydrogen packs a powerful punch—that's why it's so often used in rocket fuel. It's also the most abundant element in the universe. One of the things that holds back its widespread adoption as an energy source, however, is that on Earth, hydrogen typically combines with other elements. Getting hydrogen often means either extracting or producing it, both of which can be expensive.

But now, scientists at the Pacific Northwest National Laboratory (PNNL) have found a pairing of minerals that surpasses other precious metal materials when it comes to producing hydrogen.

This is just in the laboratory for now with no word if it can scale to industrial volumes but an interesting development.
