CHOSS / SOFC Description
CHOSS – Combined Hydrogen Oxygen Storage System Standard industrial strength hydrogen peroxide and metal hydride
supply system provide separate streams of hydrogen and oxygen for electric power generation via Solid Oxide Fuel Cell and shaft power via waste heat recovery.
High energy dense, air-independent power system Underwater power generation applications Space based power applications
SOFC – Solid Oxide Fuel Cell Electrochemical conversion of hydrogen oxidation to electric
power. Solid oxide electrolyte requires high temperature operation which
enables very high cycle efficiencies via waste heat recovery.

High storage density supply of H2 and O2 enables efficient power generation without access to atmospheric air.

MgH2Reactor H2
MgH2Supply
CHOSS Concept
MgH2 + H2O → MgO + 2 H2 (ΔHR = -283.3 kJ/gmol MgH2)
• High efficiency, air independent power. 5X-7X higher energy density than Li ion batteries.
• Can operate without ingesting water or exhausting product, providing both silent operation and neutral buoyancy
• Produces DC electric and/or shaft power
• Higher efficiency operation with waste heat recovery
• Recyclable products
• Uses standard industrial strength peroxide – safe operation
