Hydrogen Station
By: Andrew Lohr, George Asbeck, Joe Dodd-O, and John Ryen
Mission Statement
Our goal is to design a hydrogen station that distributes hydrogen in an efficient, safe, inexpensive, and convenient manner.

Our group considered cities around the world to implement our model of hydrogen city

We picked our cities on the basis of economic strength and access to green energy

After selecting 3 cities that we felt best embodied these principles, we selected our hydrogen city
Cities Stockholm, Sweden San Diego, California Geneva, Switzerland

In order to sustainably supply H2 city, a clean, efficient source of energy is needed

The geography of San Diego makes it accessible to all forms of renewable energy

Our group decided to research deep geothermal energy, an emerging type of renewable energy
Popularmechanics.com
Deep Geothermal energy can power the U.S. for 2,000 while releasing no CO2
friedmanpedia.pbworks.com
Superheated rock near San Diego is very close to earth’s surface, reducing costs of the project
organicpowerplus.com
Despite deep geothermal energy being very powerful and consistent, we deemed a second energy source necessary

Our research revealed a potent, renewable form of energy already on the market

Methane, produced naturally in landfills, is extracted above the enclosed landfill
prometheus-energy.com
The methane is then free to be reformed using steam reformation

While this process produces CO2, the net greenhouse effect is actually negative
CH4=72*CO2
Hours of research yielded several patents for our group to comply to
To analyze the technological aspects of the station, we benchmarked 3 active stations
After researching all the possibilities we could find, our group created concepts in several categories
These areas included production type, storage, tank location, and dispensing method among other things
With 3600 potential concept combinations, a severe screening was necessary

Our screening allowed us to create 3 final concepts
Concept Type
Feature Limited Start-Up Costs Amenities-driven Technology and Amenities
Production Electrolysis Biogas Both
Tank Location Ground level Below Ground Below Ground
Amenities Restroom/Minimart TV Pump Entertainment Wawa/Sheetz style minimart, pump entertainment
Space Minimal Moderate High
The best idea combination was then chosen through a concept selection matrix
The final pump design combines the fueling station and support structure for minimal use of materials
The roof is made with recyclable aluminum, minimizing our footprint and stress loads on the pumps
The overall station follows a Wawa/Sheetz business model, with emphasis on consumer goods
The station layout provides a lot of space for cars and trucks to move without risk of gridlock
With predicted item sales accounted for, our model predicts economic gain by the 12th quarter
