Temperature breakthrough for hydrogen storage
Diammoniate of diborane contains a high weight fraction of hydrogen, one of the highest for a stable material at room temperature
A compound first made in 1923 releases hydrogen at a lower temperature than ammonia borane, one of the most studied materials for hydrogen storage.
Efficient hydrogen storage is an important step in developing a hydrogen economy. One way of storing hydrogen is in chemical compounds that reversibly release hydrogen when they are heated. Diammoniate of diborane (DADB, [(NH3)2BH2]+[BH4]-) as a hydrogen-containing species has the potential to be a storage material, but the crystal structure of the compound that would give valuable information about its properties has not been resolved until now.
