Sandia Successfully Completes Hydrogen Storage System for GM

Green Car Congress

The sodium alanate material used to store the hydrogen resides within the tubes. Researchers at Sandia National Laboratories have successfully designed and demonstrated key features of a hydrogen storage system that utilizes a complex metal hydride material—sodium alanate. With main facilities in Albuquerque, N.M.,
