  1. H2 Station Project Team 8: Jack Breisch, Tim Kerley, Tyler Pierson, Jiang Yifan

  2. Hydrogen at both 350 BAR and 700 BAR pressure for passenger cars and commercial vehicles. • Hydrogen/natural gas blends (HCNG) containing up to 30% hydrogen at 250 BAR pressure to supply city public transportation vehicles and commercial vehicles. • Fueling station capacity × # of stations to meet all future city needs (replacing gas/diesel) • Assume hydrogen fuel cell vehicles and HCNG fueled vehicles are available. Design Criteria

  3. Goal: Convert a city from gasoline to hydrogen

  4. Location: Long Beach, CA

  5. Supply and Demand of H2

  6. Driving population of 240,000 • Average of 33.4 miles per day • Total demand of 1.2 million kg of H2 per week • 6,000 kg of H2 per week per station Demand Analysis

  7. Stations will typically have six 350 bar pumps and two 700 bar pumps • Stations with less traffic will have three 350 bar pumps and one 700 bar pump • Separate stations for buses and other large vehicles with CNG Station Pumps

  8. Tidal Renewable Energy

  9. How much hydrogen do we need per day? • How much energy can the tidal turbines support? • What impact will these energies have? The Important Calculation

  10. The population of Long Beach is 461564, the average miles driven is 12191miles/person per year. • To drive one mile, 60 kg hydrogen need to be supported. • With the help of Cost Estimation Tool, we find that 256937kg hydrogen is needed per day. How much hydrogen do we need per day?

  11. One tidal turbines farm can reach a power of 10MW. • We want to build ten such farms. Then, the total power is 100MW. • 100MW * 24 hours = 8.64e12 j, thus, the farms can support 8.64e12 j energy per day. How much energy the tidal turbines can support?

  12. H20(l) = H2(g) + 0.5O2, ∆ H = 285.8 kj • The efficient is 80%, 285.8 kj / 0.8 = 357250 j, 1mol hydrogen is 2g, so 357250j/2g, that means to produce 1kg hydrogen, we need 178625000 j. • 8.64e12/ 178625000 = 48369, the tidal turbines can support to produce 48369kg hydrogen per day, meets 18.8% of the requirement, 256937kg per day. What impact will these energies have?

  13. Physical Model

  14. SolidWorks Model

  15. System Flow Diagram

  16. We tried to make our station as user-friendly as possible by making it similar to existing gas stations, including a standard layouts and making a similar nozzle. • Tidal power would be the best option for us because it produces more power than other systems. Solar and wind energy would need an area much bigger to produce the same amount of power. • This project would be very expensive. It is plausible, but unlikely to be successful because everyone will have to buy a new hydrogen car. Conclusion
