 Design Task  Background  Specs  Production  Transportation  Source of Power  Storage  Best Solution  Flow Chart  Prototype  Cost Analysis  Conclusion  Questions

 Standardized fueling station for a H2 city  Supply the transportation network with H2 fuel using renewable resources

 Boulder City, Nevada–25 miles SE of Las Vegas  Located about 6 miles from the Hoover Dam and 5 miles from the Boulder City Landfill  Population: 16,840  Requires about 9,000kg of H2 a day to meet transport needs

 Safe  Sustainable  350 BAR and 700 BAR for passenger and commercial vehicles.  HCNG containing up to 30% hydrogen at 250 BAR  2 stations to meet the city needs with 6 pumps at each station

 Electrolysis ◦ Water  Large energy cost ◦ Urine  Urine breaks down ◦ Microbial  Not developed  Molten Carbonate Fuel Cell  Breaks Down  Steam Biomethane  Costly

 Trucks  Constant Refill  Pipes  Costly  Produced on Site  Need of space  Produced at House  Not realistic

 Liquid  Expensive  Gas  Storage  Produced Right Before Use  Cant keep up with demand

 Solar  Lack of Space  Wind  Lack of Space  Coal  Not Renewable  Nuclear  Expensive  Hydroelectric  Not Enough Power  Methane Waste  Abundance of CH4

 Production ◦ Steam Methane Reforming  Transportation ◦ Trucks-H2 ◦ Piping-CH4  Storage ◦ Liquid  Source of Power ◦ Methane

 Steam Methane Reformer -> $20,000,000 +  Pipelines -> $10,000,000 +  Cost of Stations -> $17,324,000  Total Cost of System -> $57,324,000

 Sell 350 and 700 bar at 4$ a kg ->$30,400 per day  Sell HCNG at 5$ a kg -> $37,500 per day  Cost to pump -> $40,000 per day  50 employees to run system -> $7,000 per day  Nitrogen -> $5,000 per day  Methane -> $2,000 per day  Total Profit -> $13,900 per day  Yearly Profit -> $5,073,500 a year

 The system will be paid off in a little over 11 years  This system is replica table around most cities that have landfills in the vicinity  We could sell hydrogen for other city needs
