Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown for the first time that a cheap catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial device. The electrolyzer technology, which is based on a polymer electrolyte membrane (PEM), has […]

University of Waterloo scientists have created an ‘artificial leaf’ by inexpensively recycling and converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology, outlined in a paper published in the journal Nature Energy, was inspired by the way plants use energy from sunlight to turn carbon dioxide into food. Yimin Wu, an […]

Pacific Northwest National Laboratory scientists have uncovered a root cause of the growth of needle-like structures – known as dendrites and whiskers – that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire. Such defects are a major factor holding back the batteries from even more widespread use and further improvement. […]
