SiGNa Chemistry Demonstrates Sodium Silicate-Based Hydrogen Generation System for Portable Fuel Cells

Green Car Congress

Prototype sodium silicate hydrogen generation system as presented earlier this year at DOE merit review. The H300 utilizes real-time swappable cartridges that generate hydrogen on demand using SiGNa’s proprietary sodium silicide (NaSi) powder. Sodium-Silica-Gel: 2Na-SG + H 2 O → H 2 + Na 2 Si 2 O 5.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Practical hydrogen storage materials must take up and give off hydrogen at standard pressure and room temperature; accommodate a large amount of hydrogen in as little space as possible; and release it rapidly and on-demand. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2. formed in the dehydrogenation.
