EFFECTIVE USE OFHYDROGEN IN TRANSPORTATION Presentation to: INDIA ENERGY CONFERENCE New Delhi, India October, 2008 Frank Lynch Eden Hydrogen Littleton, Colorado, USA
http://spiff.rit.edu/classes/phys240/lectures/elements/elements.htmlhttp://spiff.rit.edu/classes/phys240/lectures/elements/elements.html Hydrogen is the most abundant element in the universe (~90%).
The Earth is a water planet. • 70% of Earth is covered by water. • 2/3 of H2O is H2. • Energy must separate H2O to Make H2. Photo courtesy of NASA
Hydrogen, like electricity, carries energy but neither is a source of energy.
Hydrogen Energy System Goal: Make Energy Use Part Of Earth’s Water Cycle
Most hydrogen is made by steam-methane reformers and used on-site to make fertilizers, methanol and other chemicals. • Some of the largest reformers are used at oil refineries for processing petroleum. • So-called “merchant hydrogen” is produced at one location and is transported to an end-user by truck, rail or barge. • Most merchant hydrogen is liquefied at the plant and stored for filling -253ºC “cryo” tank trucks. 1 million m3/day Martinez, California, USA Photo Courtesy of Air Products

Cryogenic storage “dewars”can be built at any scale. This 420-liter container was built for NASA by Eden Cryogenics. It is suitable for liquid nitrogen, liquid oxygen or liquid hydrogen. Photo courtesy of Eden Cryogenics

Hydrogen is special stuff! • Simple displacement of petroleum with H2 is not economically possible today. • Hydrogen must deliver a premium value to justify its premium price. • Fuel cells deliver premium value with zero emissions and high efficiency. • Hythane delivers premium value with low emissions and high efficiency.
Hythane®* prototype 1990 Hythane is H2 in natural gas. *Hythane is a Registered Trademark of Eden Hydrogen
Forms of “Leverage” (premium value) • Emissions Leverage: emissions reductions exceed the H2 energy in Hythane. • Efficiency Leverage: efficiency increases exceed the H2 energy in Hythane. • Economic Leverage: Co-product streams have high value (e.g., Cl2, C nanotubes).
Transmission electron microscope images of carbon nanotubes H2 and C nanotubes are co-products of a process under development by U. Queensland for Eden Hydrogen. CO2 emissions are zero for this process. The high value of C nanotubes and C credits makes H2 cost-competitive. Structure of one type of nanotube Photos courtesy of U. Queensland and Wikipedia

This remains the long term goal. We must use H2 wisely to get started now.
