Is it possible…?
…to wholly transform our fossil fuel reliance?
…to make hydrogen available and usable to consumers?
... to change the currently inadequate energy infrastructure regardless of which energy we rely on?
…to take a SMART approach to our nation’s energy future?
Hydrogen is the answer
How is hydrogen transported?
What are hydrogen’s end uses?
How is hydrogen used as an energy source? QuickTime™ and a

Transporting Hydrogen

Primarily, hydrogen is a CARRIER not a source of energy

Hydrogen Pipelines
H2 safely transported through pipelines for decades, w/o optimal system
GH2 pipeline important synergies substantial added value
Pipelining GH2 will cost ~1.5 to 2 times NG, per unit energy-distance

NG/GH2 Comparison
NG pipeline systems typically cost $US 1 per mm diameter per meter length (with compressors, meters, controls) Minimum ~30 cm diameter. NG pipeline 50 km long would
be ~ $US 15 million.
GH2 pipeline may cost 2-3 times as much ($US 40 million)

Wind and H2, an example
H2 gathered from wind energy can be transported via pipelines
Example: Great Plains wind energy delivers wind energy as
compressed H2 gas through 400 new GH2 pipelines
requires 900 of the largest, practical new electric transmissions lines

Technical challenges
pressure intensity varies seasonally

affected
Distribution Standards
Mixtures of NG and GH2 up to 100%
High pressure (>14 MPa), high-capacity (>5 GW), long-distance capabilities (>500km)
Buried terrestrial or subsea
>100 pressure cycles per year to 50% of design operating pressure.
two types of hydrogen usage for power: combustion fuel-cell conversion (most
efficient method)
NASA uses of hydrogen: lift space shuttles fuel cells to power ship
electrical systems crew drinks H2O byproduct

Hydrogen in the mix
5% hydrogen in gasoline = reduces nitrogen oxide
can be added to ethanol, methanol, and natural gas to increase performance and reduce pollution

Hydrogen on a timeline
• Today: 9 million tons produced in
US today, could power 20-30 million cars or 5-8 million homes
NASA Around the world 500
hydrogen powered cars in use (Nov. 2006)
Honda to release hydrogen fueled vehicle in 2008

• Future: GOAL: U.S. Department
of Energy’s Hydrogen Program intends to use Hydrogen to produce 10% of our total energy demand by 2030

Safety and savings
Converting to vehicles that use hydrogen fuel-cells generated by wind
Would save 3,000 to 6,000 lives in the United States annually
These savings would make it cost-competitive with gas

Hydrogen’s vast potential
“Eventually hydrogen will join electricity as the major energy carrier, supplying every end-use energy need in the economy, including transportation, central and distributed electric
power, portable power, and combined heat and power for buildings and industrial processes.”
