Alternative Fuels

Due Diligence & Technical Services

In the biofuels and alternative energies sector, E3 and its professionals have worked on alternative fuels engagements (hydrolysis & fermentation and gasification & catalytic), biodiesel, and anaerobic digestion projects. We have supported engagements on projects ranging from ethanol production facilities up to 100 million gallons per year, biodiesel facilities up to 180 million gallons per year. Our assignments have included technology assessments, environmental assessments and permitting, project planning, feasibility assessments, technical and economic due diligence, construction monitoring, and operations and maintenance reviews.

Representative Projects


Ammonia Plant

Myriant Lake Providence Succinic Acid Plant, Louisiana

E3 served as the Independent Engineer supporting the construction and term financing of a succinic acid and ammonium sulfate production plant in Lake Providence, Louisiana. The plant uses novel fermentation processes to produce high-value industrial chemicals using low-cost non-petroleum feedstocks. E3 reviewed the process technology, construction plans, capital and production costs, permitting requirements and financial projections. The facility was partially financed with commercial debt and received grants from the U.S. Department of Energy and the United States Department of Agriculture.


South Davis Digester Food Waste

South Davis Anaerobic Digester Project – Utah

E3 prepared an Independent Engineers report to support the financing of a new anaerobic digester facility in South Davis, UT.  The new facility will accept liquid and solid municipal organic wastes (primarily food processing wastes and discarded grocery store wastes) and produce pipeline-quality renewable natural gas.  E3’s scope of services included a review of technology and efficacy, feedstock procurement plans, capital costs, production costs, permitting, construction agreements and analysis of economic projections.


Red River Refinery Potatoes

Red River BioRefinery – North Dakota

E3 prepared an Independent Engineering review to support an equity investment is this proposed advanced biofuels plant located in Grand Forks, ND.  The plant will process approximately 370,000 metric tons a year of sugar beet tailings and about 110,000 metric tons of potato waste a year to produce low-carbon ethanol, renewable natural gas, and animal feed.  E3’s review included an evaluation of the efficacy of the proposed biofuel technologies.
