Abstract: A process of forming a hydrogen storage material, including the steps of: providing a first material of the formula M(BH4)X, where M is an alkali metal or an alkali earth metal, providing a second material selected from M(AlH4)x, a mixture of M(AlH4)x and MClx, a mixture of MClx and Al, a mixture of MClx and AlH3, a mixture of MHx and Al, Al, and AlH3. The first and second materials are combined at an elevated temperature and at an elevated hydrogen pressure for a time period forming a third material having a lower hydrogen release temperature than the first material and a higher hydrogen gravimetric density than the second material.
