A hydrogen storage tablet developed at the Technical University of Denmark could help lead the way to safe hydrogen powered vehicles.
"Should you drive a car 600 km using gaseous hydrogen at normal pressure, it would require a fuel tank with a size of nine cars. With our technology, the same amount of hydrogen can be stored in a normal gasoline tank", says Professor Claus Hviid Christensen, Department of Chemistry at DTU.
