The “clean energy economy” always seems to be a few steps away but never quite here. Most energy for transportation, heating and cooling and manufacturing is still delivered using fossil fuel inputs. But with a few scientific breakthroughs, hydrogen, the most abundant element in the universe, could be the energy carrier of a future clean energy society. Taking one step closer toward the elusive goal, a team of scientists from Penn State and Florida State University have developed a lower cost and industrially scalable catalyst to produce pure hydrogen through a low-energy water-splitting process.
