By T. Clayton Prestwood & Aaron Hunter
How Might Hydrogen Fuel The Future

2. Advantages Disadvantages “Cleaner” emissions Storage
Foreign energy independence
Colorless, odorless, tasteless, and noncorrosive
Nontoxic to humans
Storage
Infrastucture
Transportation
Production
Costs
EXPLOSIVE!

3. Fuel Cells: Runs off of H2 and O2 gas. Produces an electrical current.
Skips heat conversion.
High efficiency.

4. Fuel Cells (cont.)

5. Electrolysis of H2O
Clean
Inefficient
Can be mass produced

6. Electrolysis of H2O

7. Example of Methane Reforming:
Natural gas (CH4)
Pretreatment
Reforming
Water Shift
Purification
CH4 + H2O → CO + 3 H2
CO + H2O → CO2 + H2
Methane reforming
CO2
Gas steam impurities
4H2 (Pure)
CO2 + 4H2
CH4
Heat
Heat
CO + 3H2
H2O
H2O
Heat

8. H2O Splitting by heat: Uses high heat to split H2O.
Requires a Catalyst.
Highly efficient.
Groups with nuclear power plants.

9. H2O Splitting by heat:
(NH4)2SO3(aq)+H2O→ (NH4)2SO4(aq)+H2(g)
