Designing a Drop-in Hydrogen Fueling Station

  1. 1. Designing a Drop-in Hydrogen Fueling Station 2014 Hydrogen Student Design Contest Long Beach, CA May 8, 2014 In this presentation… 1. Project Scope 2. Customer Attributes 3. Liquid H2 Delivery 4. Station Design 5. User Interface 6. Safety Features 7. Site Logistics 8. Economic Analysis
  2. 2. • Low cost – current H2 stations are $2- 4 million each • Hydrogen delivered for $7/kg • Fuel 2 vehicles simultaneously, 25 vehicles per day • 5 minute fill time for 700 bar, 5 kg fuel tank • Transportable • Low maintenance • Operated and monitored remotely • Hydrogen storage should withstand 48 hr shutdown 2014 HYDROGEN STUDENT DESIGN CONTEST DEVELOPMENT OF DESIGN FOR A DROP-IN HYDROGEN FUELING STATION TO SUPPORT THE EARLY MARKET BUILD-OUT OF HYDROGEN INFRASTRUCTURE Key Rules and Guidelines:
  3. 3. Design with the Customer in Mind Low Cost No Maintenance = Compact Bring in Customers Profit
  4. 4. Why Liquid Hydrogen Delivery? • Lowest cost • Low energy demand • Minimizes equipment • Utilizes thermal properties  4 times the density of delivered gas • Existing infrastructure  80-90% of all non-pipeline H2 delivered by cryogenic liquid tankers.1 1 Technology Transition Corporation (TTC).
