7 Refueling Stations from All Four Teams Test Vehicle/ Infrastructure Performance in Various Climates Northern California Southern California Mid-Atlantic Florida Ap Additional Planned Stations (3) Additional Planned Stations (4) Additional Planned Stations (2) SE Michigan

8 Project Produces Results for Both the Public and the Industry Project Teams Raw Data, Reports Hydrogen Secure Data Center (HSDC) Located at NREL: Strictly Controlled Access Detailed Analyses, Data Products, Internal Reports Composite Data Products Pre-agreed upon aggregate data results for public Detailed Data Products Only shared with company which originated the data No confidential information

9 Dynamometer and On-Road Fuel Economy

10 Vehicle Range Based on Dyno Results and Usable H2 Fuel Stored On-Board Data indicate improved H 2 storage technologies capable of being packaged in a vehicle are necessary to meet range targets

11 Summary First year of the 5-year project completed 59 vehicles now in fleet operation Several new refueling stations opened No major safety problems encountered Project has identified current technical status relative to program targets Will track improvements from 2nd generation stacks/vehicles introduced mid-way through project Future public results will include: FC durability, reliability, efficiency, and start-up times H2 production cost, efficiency, and maintenance

16 Power Park Project (DTE, DaimlerChrysler, BP)

17 Approach: Process Flow Diagram System Operations Center (not shown): Provides remote monitoring & control, all data acquisition and web access All AC systems connected to common 480 V Bus

18 Objectives Project Objectives Develop and test a hydrogen co- production facility having stationary fuel cell power and vehicle fueling capability that uses renewable & non- renewable resources (FY04) Employ representative commercial units under real-world operating conditions (FY04) Based on performance data, project experience, and market assessments evaluate the technical and economic viability of the power park system (FY05) DOE Objectives By 2008, validate an electrolyzer (powered by a wind turbine) with capital cost of $600/kWe and efficiency of 68% (incl. compression to 5,000 psi)* By 2008, develop a dist gen PEM fuel cell system that achieves 32% electrical efficiency and 20,000 hours durability at $1500/kW *when built in quantities of 1,000

19 Objectives Project Objectives Contribute to development of relevant safety standards & codes required for commercialization of hydrogen-based energy systems (FY04) Identify system optimization and cost reduction opportunities including design footprint, co- production, and peak-shaving applications (FY05) Increase public awareness and acceptance of hydrogen-based energy systems (FY04-F09) DOE Objectives Determine the relevant codes, safety standards, and engineering data required for Power Parks Obtain real-world operating data to better understand performance, maintenance, operation, and economic viability of Power Parks

20 Approach: Project Overview Design, install, and operate an integrated hydrogen co-production facility utilizing:  Electrolytic hydrogen production (2.7 kg/hr, 43 kg/day)  50kW (DC) stationary fuel cell power (320 kWh/day)  5000 psig vehicle dispensing (15 kg/day)  Renewable on-site solar energy (27 kW)  Grid-connected biomass energy Collect, analyze, and report system performance data & lessons learned for an integrated co-production facility operating under real-world conditions Evaluate commercialization opportunities for an advanced Power Park facility

21 Accomplishments: V alidated electrolyzer with capital cost of $1500/kWe and efficiency of 59% DTE HTP Demonstration Project Electrolyzer Measured running efficiency* 59% (DOE 2008 goal 68%) $1500/kWe (DOE 2008 goal $600/kWe) Off Peak operation (16 hrs/day) - 43 kg/day production 2.7 kg/hr production rate Projected System Performance (manufacturer quote, 2006 prices) Manufacturer rated efficiency 62.25% $700/kWe (DOE 2008 goal $600/kWe) Off Peak operation (16 hrs/day) kg/day production 90 kg/hr production rate * SNL data analysis for steady operatio
