Novel sugar-to-hydrogen technology promises transportation fuel independence
...lls. Most industrial hydrogen currently comes from natural gas, which has become expensive. Storing and moving the gas, whatever its source, is costly and cumbersome, and even dangerous. And there is little infrastructure for refueling a vehicle. "We need a simple way to store and carry hydrogen energy an...Predicting catastrophic transitions
