11 Adsorbed Natural Gas (ANG) System for Light-Duty Vehicles Design and demonstrate a 10GGE commercial prototype Adsorbed Natural Gas (ANG) system that integrates the three essential features: novel sorbent materials, an active thermal management system, and a conformable Smart Tank. Due to the inherent non-linearities in the scale-up of gas flow in porous solids, heat conduction in packed beds, and stress distributions in tanks, a integrated systems approach that focuses on a full-scale prototype is essential to ensure correct design trade-offs among the critical components, going beyond ARPA-E requirements. Key Personnel > GTI (Prime): Overall PM, MOF adsorption isotherms testing, poisoning limitations, thermal management and system integration, and full-scale system testing > Argonne: Thermal modeling, POP material investigation > NW University/ NuMat: MOF screening, performance modeling, small-scale synthesis Technology Impact Project targets 9.2 MJ/l volumetric capacity at 35 bar 250 bar) and 12 MJ/kg gravimetric density (2 x s all steel tank) in a tank with a 90% conformability factor using a $10/kg material ($500 per 10GGE material cost). Achieving these goals should yield a 5 year payback for personal car. Similar range at reduced cost and lower operating pressure will dramatically improve the market adoption rate of NGVs. Challenges: Material identification, cost-effective synthesis, heat management design, poisoning of bed, tank conformability/cost tradeoffs, manufacturability of MOF-tank system, durability & longevity unknowns. TRL-3 to TRL-6 w/ working prototype system at full-scale. 11

12 Strategies to Shift Gas Industry Practices and Cost-Effectively Grow the NGV Market Goal: Achieve major impact on long-term NGV infrastructure investment by aligning utility operations and NGV fueling station needs to efficiently deploy capital. Address regulatory barriers. 1. Maintain high-pressure gas service downstream of city gate (bypass gate stations and take advantage of sunk cost in pipeline compression capacity). 2. Move micro/mini storage into LDC operations to supply NGV stations and integrate into utility peak demand management solution set. 3. Integrate LNG storage operations into vehicle fueling operations. 12
