Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material.

Dr. Tue Johannesen - one of the inventors of the Hydrogen Tablet - proves the safty of the most secure and efficient hydrogen storage in the world.
With the new hydrogen tablet, it becomes much simpler to use the environmentally-friendly energy of hydrogen. Hydrogen is a non-polluting fuel, but since it is a light gas it occupies too much volume, and it is flammable. Consequently, effective and safe storage of hydrogen has challenged researchers world-wide . . .

Oh, those liberal Danish devils will ruin our way of life.

I wonder if Bush will liberate Denmark from those sodrug spammert Liberals.   ;D

Ah, I see that the key is efficient storage of ammonia on an appropriate substrate - which makes perfect sense.  I imagine though there are some technical issues like storage temperature - anywhere from -30 to 50°C (-20 to 120°F).

Then I have to wonder where the ammonia is cracked to form 3H2 and N2.  Cracked ammonia is used to produce a reducing environment in some sintering furnaces in the production of certain ceramic materials, and it is feasible as a fuel.  Presumably the hydrogen is used in fuel cells or some type of combustion engine.  I have to wonder if the latter would still raise a concern over nitrogen oxides NOx.
