Sandia Successfully Completes Hydrogen Storage System for GM

Green Car Congress

The hydrogen storage system Sandia designed for GM. 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. For GM, the enduring value of this project can be found in the design concepts, computational tools, and control strategies that Sandia developed.

Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

Turbo-alternator-shaft design for the SNL S-CO 2 test loop. The key component of these loops is the turbo-alternator-compressor unit (TAC) and the technologies used in its design. Because of the extremely high power densities and fluid density, Sandia has filed a Technical Advance for the TAC design.
