  1. PILOT Hydrogen Reduction Field DemonstrationandCommercialization Implications D. Larry Clark JUSTSAP/PISCES 2008 November 12, 2008

  2. The PILOT has Landed

  3. Integrated Oxygen Production Demo 17 kg/batch H2 Reduction Reactor Lift System and Auger Loading Oxygen Liquefier/Storage Bucket Drum Excavator Salt Extraction Collector Water Condenser Product Processor Hydrogen Storage Lander Simulator

  4. Design Requirements System Production Requirements • 1 kg per day oxygen production Demonstration Testing Requirements • 2 batches in a daily production demonstration • Performed in Earth ambient environment • Modules field mobile and reconfigurable Derived Requirements • 1% oxygen recovery by mass • 17.6 kg regolith batch size – 176 grams O2 per batch

  5. Soil Handling Subsystem • Soil Lift • Auger transfer • Internal Auger • Keeps soils off of sealing surface • Dual vacuum seal • Heat recovery system • Uses phase change material around internal auger Phase-change material Auger flights Outer shell

  6. Hydrogen Reduction Reactor • Rotating Reactor • Spiral flights to pull in, expel soil • Electric Resistive heaters • 17 kg batch size

  7. Gas Recovery And Circulation Subsystem • Circulates reactant and steam product • Pumps off out-gassing components • Could be collected on Moon • Hydrogen reclamation • Stored as high pressure gas for next batch

  8. Gas Cleanup and Water Collection Subsystem • Gas scrubber for sulphur and other reactive components • Condenser • Water collection vial • Will collect over 1 kg this morning

  9. Water Electrolysis Subsystem • Water buffer storage • Low pressure bladder • Two stage water cleanup module • High pressure pump • Fills electrolyzer under high pressure • Cathode feed electrolyzer • 5 kW enough to provide over 1 mT oxygen per year • Reduces system complexity • High pressure hydrogen storage

  10. Cryogenic Storage Subsystem • Inlet gas dryer • Vacuum jacketed vessel • Capable of integrating cryocooler • Liquid outflow line

  11. Robotic Bucket Drum Excavator • Bucket Drum Concept • Combines high cutting force and excavation efficiency with transfer characteristics of overshot loader • 10 kg per drum load • 18 kg load in dump bed
