Scientists at the Energy Department’s National Renewable Energy Laboratory (NREL) announced advances have been made toward affordable photoelectrochemical (PEC) production of hydrogen. PEC is solar energy driving a semiconductor coated with a catalyst that for this example chemically splits hydrogen from water. The NREL work shows that molecular catalysts can be as highly active as […]

Carnegie Institution’s Rebecca R. Hernandez (now at University of California Berkley), Madison K. Hoffacker, and Chris Field found that the amount of energy that could be generated from solar equipment constructed on and around existing infrastructure in California would exceed the state’s demand by up to five times. The team offers that further development of […]

California Institute of Technology scientists inspired by a chemical process found in leaves have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel. Nate Lewis, the George L. Argyros Professor and professor of chemistry at Caltech explains the high point, “We […]

Northwestern University scientists are the first to develop a catalyst that can perform a remarkable feat found only in nature: take nitrogen from the air and turn it into ammonia under natural conditions. (Ammonia is the critical component in fertilizer.) If fully realized the process might displace more than 1 percent of world energy use. […]

Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed a new and efficient way of producing hydrogen fuel from sunlight and water. Connecting together solar cells made with a mineral called perovskite and the team’s low cost electrodes achieves a 12.3 percent conversion efficiency from solar energy to hydrogen. The profusion of tiny bubbles […]
