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

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

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

Fuel Cells (cont.)

Electrolysis of H2O Clean Inefficient Can be mass produced

Electrolysis of H2O

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

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

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