Addressable Applications

• Man-Portable Self-Contained Generators (10W-3 kW)   › Small portable (National Security; Homeland Security; Commercial) › Large portable (National Security; Homeland Security; Commercial) • Materials Handling Equipment (MHE)/Utility Vehicles (4-14 kW)   › High pressure remote buffer – feeding fuel cell › Low pressure system – on-board generation • Steam & Heat Generation (propulsion)   › Navy UUVs/Torpedoes › Commercial UUVs • Miscellaneous   › UHP K-cylinder replacement for back-up power and labs › Gas generation unit for propellants/inflatable devices › School demo unit

Portable (10W to 3 kW)

• Customers:   › US Special Forces › Tank & Armaments Command (Silent Watch applications) › Homeland Security (Emergency Preparedness/First Responders) › Commercial remote › Electronic newsgathering • Drivers:   › Silent, lightweight power source, rapid recharge, easy to use › Long shelf life standalone power, non-toxic › Off-grid power where required • HPI Technology: CRU, CBU lab demonstrator systems   › Cartridge size tailorable to specific needs (10g-3kg) — 10g = 10W for 70 minutes — 3kg = 1kW for 220 minutes › System operates with any available water source › Simultaneous hot water co-generation if desired

MHE/Utility Vehicles (4-14 kW)

• Customers:   › Large retail stores with 1-3 forklifts on site › Small warehouses • Drivers:   › Low cost › Pure hydrogen on-site › Potential for waste recycle › Non-toxic • HPI Technology:   › Upscaled CBU-high pressure system on-site › Uprated CRU-low pressure system on-board

MHE/Utility Vehicles

• High pressure CBU system   › H2generated at 6,250 psi, stored in on-site receiver › High pressure 5,000 psi storage tank on vehicle › Potentially expensive • Low pressure CRU/CBU system   › Digitized on-board system (lower potential energy, safer) › H2generated at < 300 psi › Small buffer tank on vehicle › Potentially lower cost

UUVs & Torpedoes

• Existing technologies:   › Various advanced batteries, advanced diesel hybrids › Complex powder flow aluminum-steam combustor systems • HPI technology:   › CBU, delivers steam from fixed cartridges • Customers:   › DARPA; US Navy; Foreign Governments › Commercial • Drivers:   › Longer range/extended operating time › Simplicity/reliability › Safety; non-toxic materials; rapid recharge › Reduced mission costs (power unit cap-ex/op-ex; storage; disposal)

UUVs & Torpedoes Capabilites

*Projected CBU-8 or CBU-12 is cheaper, has fewer components and has no disposal issues compared to present powder-based Aluminum Combustor
