Scientists Develop Liquid Hydrogen Storage Solution

Scientists Develop Liquid Hydrogen Storage Solution

Hydrogen can be stored either as a gas, or as a liquid. Storing liquid hydrogen , however, requires extremely low temperatures of -423 F/252 C, while keeping it under very high pressure pressure . Any hotter, and the hydrogen will boil off. As you can imagine, keeping something that cool constantly requires some very intricate, very expensive technology. Gaseous hydrogen requires being kept under pressure between 5,000 and 10,000 psi , not exactly easy or cheap either, and much more difficult to transport and store. University of Oregon researchers, led by Shih-Yuan Liu, have managed to put together a nitrogen-based liquid storage solution for hydrogen that is safe and stable in room temperatures, in open air, and will release hydrogen in a controlled, safe way at sustainable temperatures . In other words, clean, stable, usable fuel that can utilize existing infrastructure...
