Hydrogen: transport, distribution, and end use Annie Brandjord Bevan Flansburg Stephanie Hyde Cristen McLean Megan Sparks

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?

Transporting Hydrogen Primarily, hydrogen is a CARRIER not a source of energy http://nanopedia.case.edu/NWPage.php?page=hydrogen.transport

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 Anne http://infotools.hfpeurope.org/energyinfos__e/hydrogen/main10.html

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) Anne http://www.pttplc.com/th/ptt_core.asp?page=ap_ov_ng

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 Anne http://www.clever-ideas.com/news.asp?id=3

Technical challenges pressure intensity varies seasonally exacerbates H2 attack on pipeline steel hydrogen-induced cracking hydrogen corrosion hydrogen embrittlement valves, meters, compressors similarly affected Anne

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. Anne, do we need this or could you incorporate this somewhere else

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 Jacobson, who has no financial interest in any wind or hydrogen endeavor but whose commitment to clean air is manifest in his choice of car (a Toyota Prius), house (it's solar-powered) and career (atmospheric scientist). Save more lives than were lost in the WTC attacks http://news-service.stanford.edu/news/2005/july13/hydrogen-071305.html http://news-service.stanford.edu/news/2005/july13/hydrogen-071305.html

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.” cristen http://www.hydrogen.energy.gov/enduse.html
