What we’ll be talking about…

Standardized fueling station for a H2 city

Supply the transportation network with H2 fuel using renewable resources

Our Mission

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 about9,000kg of H2 a dayto meet transportneeds

Where we’ll be stationed…

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

In a perfect world…

Electrolysis◦ Water

Large energy cost◦ Urine

Urine breaks down◦ Microbial

Not developed

Molten Carbonate Fuel Cell Breaks Down

Steam Biomethane Costly

How will we produce it?

Trucks Constant Refill

Pipes Costly

Produced on Site Need of space

Produced at House Not realistic

How to get it to the station

Liquid Expensive

Gas Storage

Produced Right Before Use Cant keep up with demand

Storage/Distribution

Solar Lack of Space

Wind Lack of Space

Coal Not Renewable

Nuclear Expensive

Hydroelectric Not Enough Power

Methane Waste Abundance of CH4

Source of Power

Production◦ Steam Methane Reforming

Transportation◦ Trucks-H2◦ Piping-CH4

What we envision

Steam Methane Reformer -> $20,000,000

+ Pipelines ->

$10,000,000 + Cost of Stations ->

$17,324,000

Total Cost of System -> $57,324,000

The initial Cost…

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

Profit Per Day

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

Paving the way for the future
