Hydrogen is the most abundantelement 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.

Hydrogen, like electricity, carries energybut neither is a source of energy.

•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.

Reformers may be scaled down for onsite production of hydrogen.

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.

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 1990Hythane 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).

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.

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