Design a Hydrogen Generator

SiGNa’s new class of sodium silicide powders (NaSi) readily produce hydrogen with far less system complexity than other high density hydrogen storage methods.

Significant System Benefits for Portable Power Applications (1 W to 3 kW)

• Safety: Does not ignite or oxidize in air at standard conditions even when fully exposed to air (i.e. opened storage canister)
• Thermal Stability: Material is stable over all practical temperature ranges (-55 to 500°C)
• Storage: The material has been demonstrated to have a shelf-life of over two years but is capable for being stored for significantly longer
• Pressure: The maximum developed pressure is determined by the system design not the material characteristics. The maximum pressure is expected to be a nominal 30 psi (material capable of 1000’s)
• Ease of Use: No catalyst required to produce hydrogen gas
• By-products: Generates a non-toxic aqueous waste, sodium silicate
• Low-Weight: NaSi yields 1715 W-Hr/kg (assume fuel cell conversion of 17.5 W-Hr / gm-H2)

All of these features come at a lower material and system cost. These unique attributes facilitate straightforward system integration to develop highly controllable and safe generation of hydrogen. SiGNa’s typical hydrogen generation system operates at a continuous 15 psi with near instantaneous start-up time. The exact operating pressure is controllable based on application specifics.

SiGNa Chemistry’s Alternative Energy Business is focused on the development of custom developed hydrogen-generation-cartridges and/or portable power systems requiring up to 1 kW. SiGNa is currently expanding its relationships with OEMS, distributors, and developers to commercialize its portable power technology.
