Did you know that when hydrogen fuel is burned, it only emits heat and water? You probably know that hydrogen is the most abundant element in the world and that combustion of hydrogen gas is powerful enough to launch rockets out of our atmosphere. So why aren't we using hydrogen for all of our energy needs? Because on earth, hydrogen is never found isolated, but locked up in other molecules (most commonly H2O). But in Spain, they've discovered how to isolate hydrogen gas from water using the power of the sun! Hello future?
A power plant that makes hydrogen by splitting water with concentrated sunlight launches in Almeria, Spain, on 31 March. It's a glimpse into a possible carbon-free future that uses solar-driven chemical reactions to produce the gas.
