Sodium Aluminum Hydride

The Aldrich Materials Science Team congratulates Dr. Ragaiy Zidan from Savannah River National Laboratory on receiving a U.S. Department of Energy Hydrogen Program Team Award for the development of novel electrochemical methods for the regeneration of aluminum hydride (alane, AlH₃).¹

Dr. Zidan’s method² uses a specifically formulated solution of NaAlH₄ in tetrahydrofuran (Aldrich Prod. No. 698865),^3,4 developed by Aldrich Materials Science for use as the hydride source and electrolyte in the preparation of AlH₃ by electrolysis as show in Equations 1 and 2.²

Aluminum hydride (AlH₃) has a high hydrogen content of 10 wt.% and a hydrogen release temperature of ~100°C, and is a primary hydrogen source for fuel cells used in portable electronics and transportation. ⁵
