We have a class of materials in which we can change the components nearly at will. There is no other class of materials where one can do that. The exciting discovery we are reporting is that, using a new material, we have identified a clear path for how to get above seven percent of the material?s weight in hydrogen.

We have achieved 7.5 percent hydrogen; we want to achieve this percent at ambient temperatures. We can store significantly more hydrogen with the MOF material than without the MOF.
