Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have discovered a way to isolate hydrogen and oxygen by splitting water molecules through absorbed sunlight, according to a paper published in this month's Nature Energy. This method uses photoelectrochemical (PEC) devices to divide molecules in order to isolate the H from H20. Conventionally, hydrogen is isolated by a process that relies on natural gas, but PEC devices would cut out the need for this significantly less sustainable practice.
Researchers are currently working on making the technology durable enough for commercial use.
