Sweetwater Energy Closes Cellulosic Deal

Sweetwater Energy has announced a 15-year commercial agreement with Front Range Energy to produce cellulosic ethanol at Front Range’s current corn ethanol facility located in Weld County, Colorado. Sweetwater will install its process to convert local biomass, such as crop residues, energy crops, and woody biomass, into sugar that will then will converted to ethanol.

We’ve had great success fermenting Sweetwater’s sugar, and from a business standpoint, we have great confidence in Sweetwater’s management team.”

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. As the project ramps up, economics will ultimately determine the pace and volume with which Front Range’s corn ethanol facility will migrate to Sweetwater’s cellulosic feedstocks.

We’re going to kick this off by replacing about 7 percent of the corn currently processed, and as our partnership grows and we see how well both parties are benefiting from the cellulosic ethanol production, we’ll increase the amount of cellulosic material and really open up the cellulosic markets to Front Range.”

In December 2012, Sweetwater was awarded a patent for the manufacture and deployment of distributed pretreatment units designed for the extraction of sugars from any cellulosic feedstock for the production of ethanol.
