Design Proposal

for a Hydrogen Power Park

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

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 Systems Criteria

•Renewable fuel source

•High efficiency

•Integrated into our local community

•99.999% Fueling Reliability

Fueling Station Simulation

Simulation Methodology • More details available through poster presentation

• Stochastic Queuing Theory Model • Fueling Station – Vehicle Interactions

• Cascading Storage Algorithm • Fueling Station – Hydrogen Storage Interactions

• Daily vehicle intensities increased annually • 10 vehicles per day (2010)

• 46 vehicles per day (2019)

• One hydrogen bus (2010 – 2019)

• System evaluated every second over design horizon

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

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.
