2. Construct a city that consumes hydrogen as its primary fuel, we need an abundant energy and water supply, a hydrogen production method, transportation, storage, and distribution method.  We need to pick the best location for our hydrogen city  Hydrogen needs be produced on-site using abundant renewable sources such as wind and solar power.  Hydrogen needs to be transported and stored safely and securely.  Hydrogen fuel dispenser needs to be equipped with a compressor to dispense hydrogen and HCNG fuel at various pressures (250, 350, and 700 bar)  Fueling station needs to have a capacity of at least four vehicles at a time.  The rate of received and purchased at fueling stations needs to be minimized and controlled to increase safety.

3.  Houston ◦ Has basic hydrogen fueling infrastructure in place  Includes a few actual fueling stations and a pipeline system for the stations ◦ Mayor has drafted three separate plans to change Houston into a hydrogen city  Called Road Map to Hydrogen  Has three different ‘road maps,’ where the first is a wait and see approach and the third is a push straight into changing the city completely and the 2 nd approach is the moderate, slower approach to changing Houston. ◦ Is capable of using Solar, Wind, Biomass, and Fossil Fuels to generate hydrogen fuel. ◦ Has large body of water semi-near the city ◦ Because storage would be underground, fuel would be safe from any tropical storms that could otherwise harm it ◦ Has 2 hydrogen production plants nearby ◦ Population is willing to make the change  San Diego ◦ Population is willing to make the change ◦ Capable of using Solar (in great quantities), wind, and fossil fuels to generate fuel ◦ Possible safety hazard from earthquakes ◦ Close to Pacific Ocean ◦ Fair sized population ◦ New infrastructure would be required

4.  Las Vegas ◦ Is capable of using Solar, wind, and fossil fuels to generate fuel ◦ Hoover Dam is large source of fresh water for electrolysis and electrical energy ◦ Large public transportation system which would benefit from hydrogen fuel ◦ Possibility of droughts ◦ Population is willing to make the change ◦ New infrastructure would be required  New York City ◦ Population is willing to make the change ◦ Near the Atlantic Ocean (large water source nearby) ◦ New infrastructure would be required ◦ The city is a trend setter ◦ Has a large public transportation system ◦ Large population ◦ Is capable of using wind, solar (to a point), and fossil fuels to generate fuel

6. Based on our intensive research of Houson, San Diego, and Las Vegas, we discovered that Houston, TX is the best option.

7.  It already has a basic in-place infrastructure for a hydrogen city (the Road Map to Hydrogen)  It has two nearby hydrogen plants: one in Galveston, TX and the other in Cleveland, TX  The only safety hazard would be tropical storms/hurricanes but because the fuel would be stored underground, they should not pose a serious threat  It could use solar and wind and biomass as possible sources to produce fuel  To dispense fuel we would reformat gas stations to store hydrogen at 250, 350, 750 BAR  Has a fair amount of rainfall (fresh water), and the Gulf of Mexico is in the region  The Mayor is already supporting cleaner air (greener lifestyle) acts

8.  Impact ◦ Houston already has a basic infrastructure in place for hydrogen fueling including an in-place, albeit small pipeline system  More pipelines would be needed, and space would be limited ◦ Houston already has two nearby hydrogen production plants, so no large scale facilities need be built ◦ Houston is currently one of the 25 ‘Solar American Cities,’ and are looking to further their solar infrastructure  Awnings on site will be equipped with solar panels to generate the required electricity ◦ There are currently 1239 gas stations in Houston  Changing half to hydrogen (because not everyone will change vehicles right off the bat) means approximately 684 fueling stations at the end of the entire process ◦ Population of 6,127,645 (including Sugar Land) so it will cause a fairly large disturbance, but because changes already underway it should not be as crazed as other larger cities  A greener lifestyle is popular in the region, there should be a minimum of negative feelings towards the change

9.  Fuel Dispensation ◦ Fuel will be dispensed in the same basic method as gasoline (paying at the pump, etc.) ◦ Storage tank will be connected to gas compressor to dispense fuel at 250, 350, 750 BAR ◦ At a hydrogen station in Des Plaines, Illinois (outside of Chicago) hydrogen fuel costs 3.49$ per kg  Fuel at our stations will try to meet his price ◦ Pump must be equipped with a gauge to monitor when the car’s tank is full  Power for Operations ◦ The stations will be powered primarily by the city’s electrical grid  Storage ◦ Fuel will be stored underground in pipelines (some of which are already in place) ◦ These underground lines must have a line to the two hydrogen plants mentioned so that constant trucking to sites is not required

10.  Safety ◦ All employees must be trained to handle the new equipment ◦ Because the fuel will be stored underground the possibility of explosions is a minimum (Houston is not earthquake prone) ◦ Hazards include tropical storms/hurricanes, but because the fuel is stored underground such storms should not disturb the actual pipelines  Cosmetic damage to the actual station is a possibility ◦ Pump system will be similar if not the same as for gasoline, so people will be familiar with the fueling method, however instructions will be on hand  Warnings/Instructions will be on hand  Source ◦ Houston has a large quantity of available renewable resources including solar, wind, and biomass  Also has a large fossil fuel feedstock for hydrogen production at plants ◦ Plants at Galveston and Cleveland will provide primary fuel source for storage at stations  Current hydrogen separation processes use fossil fuels to raise the temperature enough to separate H2 from water
