UCLA invention captures the sun’s energy and converts it to electricity or hydrogen gas By Gary Elinoff, contributing writer Solar and wind energy are abundantly available worldwide at no cost, but the big problem is the difficulty in storing it. Mechanical devices such as flywheels are inefficient. Lithium-ion batteries are difficult to produce and bulky, and, as is highlighted all too often in the news, they are unstable, prone to catching fire and to explosion. And supercapacitors , the new star on the scene, can’t as yet store enough energy for their size and weight. Enter hydrogen One possible way to store electrical energy is to convert it into hydrogen gas, which can later be used as fuel for a fuel cell. The great thing about hydrogen-powered fuel cells is that their only “exhaust” is water, which makes them an almost environmentally perfect power source for electr...
