Advanced Hydrogen Storage - Combining Hydrolysis and Thermolysis to Achieve >15wt Energy Density and Controllable Hydrogen Generation

摘要

SiGNa Chemistry will discuss the development of its silicide hybrid, a material that combines the best of hydrolysis and thermolysis chemistry to achieve high gravimetric energy density (>15%wt) in a lightweight and thermally-stable form. Silicide hybrids combine the best features of two chemicals: high-energy density from sodium borohydride (NaBH4) with the fast kinetics from sodium silicide (NaSi). The resulting air-stable powders demonstrate improved reaction kinetics and allow hydrogen production at significantly lower temperatures than previously possible. They are also non-flammable and do not react with oxygen nor decompose by heat under storage.
