Researchers at EPFL in Lausanne, Switzerland, have developed a photocatalytic system that can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and put to use.
The transition to sustainable energy sources faces many challenges. One important one is to make those sources as reliable as conventional energy systems. For technologies like solar and wind power, which can’t operate around the clock, an enabling element is effective energy storage. Energy storage is critical for both the electricity grid and for transportation.
