Danish Researchers Develop Hydrogen Tablet

We all know we want to be cruising in hydrogen cars, but there are some safety issues associated with a vehicle whose fuel tank amounts to a powerful bomb of highly compressed hydrogen. Now, Danish scientists have made what they say may be an important step in the direction of safe and inexpensive hydrogen storage. Developed at the Technical University of Denmark, a new hydrogen tablet chemically stores hydrogen in a safe, solid form. The tablet consists of ammonia absorbed in sea salt. Ammonia is produced by a combination of hydrogen with nitrogen from the surrounding air, and the tablet therefore contains large amounts of hydrogen. A chemical catalyst releases the hydrogen when needed. Scientists claim the hydrogen tablet is so safe is could be carried in your pocket. :: DTU
