Ammonia - The "other hydrogen."

Ammonia-Fueled Combustion Engines are Coming.

HEC projects their ammonia-fueled engines will produce 2.33 times more horsepower
than a gasoline-fueled engine and plan to have finalized systems ready for sale in 2008.
--------------------

Hydrogen Engine Center, Inc announced today that HEC and Sawtelle & Rosprim, Inc.
("Sawtelle") will work together to design and build tHydrogen Engine Center, Inche
world's first Ammonia Fueled Irrigation Pump System for the purpose of meeting
California's new emissions requirements scheduled to go into effect in 2010.

Plans include integrating HEC's ammonia-powered engines with Sawtelle's pump
technologies and expertise to complete a prototype system for testing and evaluation.
The prototype system is being designed to run 24 hours a day and is expected to be
tested in California during the 2007 irrigation season. HEC intends to begin selling the
finalized system into California during 2008.

"We believe that the demonstration of this engine will complete years of development
work and will allow the sale of our systems worldwide without concerns about hydrogen
storage, cost, availability or permitting," says Ted Hollinger, HEC President. "With the
success of this project, we hope to move ammonia-fueled engines into the genset market."
By having a broad range of products, along with the ability to work with "both
hydrogens", HEC plans to provide engines with substantial power ranges that are
environmentally friendly.

Ammonia (NH3), also known as anhydrous ammonia, which the agricultural industry has
relied on as a fertilizer for many years, contains no carbon, stores like propane and is
the second most prevalent chemical in the world. Ammonia contains more hydrogen per
cubic foot than liquid H2. Hollinger considers ammonia the "other hydrogen."

An infrastructure for ammonia is already in place, as transporting and storing the fuel
is much like that of propane. Usage and safety regulations for ammonia are already in
place, therefore, the process of obtaining a permit to use ammonia is usually relatively
simple. Ammonia pipelines can be found in many areas of the United States, including
Iowa, and distribution of the fuel is already established.

HEC has established an Oxx Power(TM) engine line-up capable of running on a multitude of
fuels, including hydrogen, making the decision to design ammonia-fueled engines the next
logical step.

"Ted Hollinger's presentation was one of the highlights of the conference.
If the Hydrogen Engine Center ammonia fueled commercial internal combustion engines are
as high
in efficiency (50%) as Ted Hollinger indicates, it will be difficult for fuel cells to
compete," commented Norm Olsen, P.E., Manager of Iowa State University's BECON (Biomass
Energy Conversion) Facility in Nevada, IA.
