UNLV Uses Sunlight to Make Hydrogen from Water

Billed by UNLV as “an advanced method of generating hydrogen,” this scheme allows water to absorb energy directly from sunlight, breaking the liquid into its consistent elements. Solar photons do not have quite enough energy to perform this separation on their own (otherwise all liquid water on the planet would disassociate under direct sunlight). So, catalysts lower the reaction barrier while an embedded solar panel provides the extra energy needed to move the reaction forward, generating hydrogen and oxygen gas.
