Design Proposal
for a Hydrogen Power Park
2. Humboldt State University Student Design Team
Definition of a Hydrogen Power Park
• Small to medium sized energy station in
close proximity to energy consumers
• Providing:
• Combined heat and power
• Hydrogen fuel
• High efficiency
• Reliability
• Reduced CO2 production
3. Humboldt State University Student Design Team
Design Criteria
H2U Guidelines
•Minimum of 100 kW
Electrical Output
•Fueling
• 2010: 50 kg per day
• 2019: 250 kg per day
•21,000 ft2 footprint
•Onsite hydrogen
production
•Safety is paramount
Evolution Energy

Fueling Station Simulation
Simulation Results
• Equipment installation schedule over design horizon
• Station Serviceability (Design Year 2019)
• Approximately 17,000 vehicles serviced
• 28 vehicles waited with an average wait time of 2 minutes
• Daily Average: 45 vehicles and 1 Bus
• Maximum Observed Intensity: 11 vehicles in an hour
• Excess Hydrogen production (Design Year 2019)
• Daily Average: 38.8 kg-H2

20. Results Of Economic Analysis
• “Six nines” H2: $39 - $47 per kg delivered
• By selling excess H2 for $47/kg in Silicon
Valley, we can sell H2 for $2.50/kg at the
pump.
