i. Fossil reformation

ii. Electrolysis

iii. Co-production

b) Centralized/regional production, distribution, fueling, and vehicle operation

i. Renewable systems

ii. Fossil with sequestration

iii. Nuclear

iv. Transportation

v. Distribution

c) Integrated production and fueling station
Description: An integrated system of hydrogen production, fueling, stationary fuel cell(s), hydrogen cleanup, and 10,000 psi hydrogen storage at EPA/NVFEL. (FY05-06 timeframe)
Goals: System efficiency, Cost ($1.50 gasoline equiv.) including depreciation, Footprint, Reliability

i. Results/Learnings

a. Development and evaluation of a unique control system to monitor and optimize all key operational parameters in all system components.

b. Demonstrate capability to maintain daily fueling of several hydrogen vehicles while testing components and systems.

c. Significant reduction in delivery cost for hydrogen (Target: $1.50 per gasoline gallon equivalent, including depreciation of system components.)

d. Demonstrate effective heat recovery from high-temperature stationary fuel cell for reformer process, thermal compression, and building physical plant.

e. Demonstrate incorporation of high-temperature fuel cell into system to provide a constant sink for hydrogen production regardless of vehicle fueling demand and to generate electricity for the local grid.

f. Optimize hydrogen cleanup, using lower-energy cleanup for the high-temperature fuel cell and limiting higher-energy PSA cleanup to hydrogen for for fueling PEM fuel cells.

g. Demonstrate thermal compression of H2 to 10,000 psi to avoid mechanical compressor.

h. Minimize overall station physical footprint.

i. Significant body of collected data on real-world performance of individual system components and the overall system.

j. Demonstration of renewable hydrogen sources into integrated fueling system (including biomass and/or electrolysis from "green" electricity)

k. Publication of results and lessons learned to support other similar efforts.

ii. Analyze opportunities for renewable hydrogen sources for this location, including landfill gas and solar electrolysis.
