Nanotubes Hold Hydrogen Future

One of the most pressing of the many problems of creating hydrogen vehicles is how to safely store the hydrogen. Researchers at Stanford Synchrotron Radiation Laboratory and Stanford University are one of many groups developing carbon nanotubes to store hydrogen as the answer.

According to Phys.org, "The carbon nanotubes offer safe storage because the hydrogen atoms are bonded to other atoms, rather than freely floating as a potentially explosive gas.

The DOE’s FreedomCar initiative says that a storage system should be at least 6 percent hydrogen by weight to be feasible; the Stanford team says that it is already at 5 percent. The researchers are working on ways to improve the longevity of the nanotubes.
