If hydrogen power transportation is the future, this new hydrogen storage tech could be in your future car.
"Researchers in Israel say they've come up with a very novel way of storing hydrogen. Gone are the bulky, super-insulated tanks that can keep coffee hot for 28 days. The Israeli team has figured out a way to pack hydrogen into glass filaments that, once completed, will be slightly thicker than a human hair. The glass hairs, or "capillaries," are then bundled into a glass tube, 370 at a time, forming a "capillary array," about the width of a drinking straw. The scientists say that 11,000 of these arrays will fuel a car for 240 miles. Not bad considering they'll also take up less than half the space and weight of a conventional hydrogen storage tank. "We have shown new materials that can store more hydrogen than any other system," says Dan Eliezer, chief scientist of C.En Ltd., the company based in Geneva, Switzerland, where the Israelis are developing their invention."
