Sweetwater Energy, Inc. (Sweetwater) ,
a Rochester New York-based cellulosic sugar producer ,
announced a 15-year agreement with
Windsor,
A Corolado-based Front Range Energy,
to generate cellulosic ethanol at
Front Range's corn ethanol facility.
The agreement has a total potential
value in excess of US $ 100 million and
requires a minimum outlay by Front Range
while stabilizing the company's feedstock costs

Sweetwater will use
its patented, decentralized process to convert
locally availalbe cellulosic, non-food biomass,
such as crop residues, energy crops and woody biomass
into highly fermentable sugar,
which Front Range will ferment into ethanol.
Sweetwater
- will place one of its cellulosic facilities
near the Front Range site and
- will deliver enough refined monomeric sugar
for Front Range to produce up to
3.6 million gallons of ethanol per year
during the initial phase of the relationship
The promising economics affored by
Sweetwater's cellulosic sugar and
the patented hub-and-spoke distributed model
will ultimately determine the pace and volume
which Front Range's corn ethanol facility will
migrate to Sweetwater's cellulosic feedstock.
Sweetwater Energy has signed 2 agreements with
1. Ace Ethanol, two weeks agos and
2. Windsor, todays

About
- Sweetwater uses a unique technology to produce
low-cost sugars fron non-food plant materials including
* waste materials such as
crop residues, wood thinning, or
* non-food, purpose-grown crops such as
energy sorghums.
- This highly fermentable sugar solution is sold to refineries,
which use it to produce
* biofuels,
* biochemicals and
* bioplastics
- Sweetwater's process is a major breakthrough
for the future of cellulosic ethanol.

- Just one month agos, Sweetwater announced that
the United States Patent and Trademark Office had issued
US patent to Sweetwater for
the manufacture and deployment of
distributed pretreatment units designed for
the extraction of sugars from any cellulosic feedstock
for the production of ethanol
- The patent allow Sweetwater to deploy its
cellulosic sugar conversion facilities in a
" Hub-and-Spoke " fashion,
providing broad scale diversity for
cellullosic ethanol production that
takes full advantages of
economics and capacity constraints surroundng
cellulosic biomass.
- The patent protects the first technology to support
a viable economic model for scaling to conversion of
cellulosic biomass into highly fermentable sugar and
subsequently ethanol.
- It will mean a great deal to the U.S. corn ethanol industry
and to the profitable future of biofuel prouduction worldwide.
