Comstock Files for Cellulose Fuels Grant


Comstock Mining Inc.

VIRGINIA CITY, Nev., Sept. 15, 2022 (GLOBE NEWSWIRE) — Comstock Inc. (NYSE: LODE) (“Comstock” and the “Company”) today announced that it has filed a grant application with the U.S. Department of Energy (“DOE”) to build a pre-pilot scale system to demonstrate one of Comstock’s unique new pathways to produce renewable diesel, sustainable aviation fuel, gasoline and marine fuel from forest residues and other forms of lignocellulosic biomass with significantly improved yield, efficiency and effectiveness. cost compared to known methods.

Comstock has developed a breakthrough process that effectively deconstructs woody biomass and residues into uniquely isolated biointermediates free of the contaminants that have frustrated previous attempts to commercialize cellulosic fuels on a large scale. Comstock’s biointermediates include cellulose sugar produced from a purified form of cellulose that has been stripped of bioconversion inhibitors, and a unique blend of hydrocarbons that Comstock calls Bioleum.

Cellulose sugar can be used as a fermentation feedstock to produce ethanol, lipids and many other products. Bioleum is a form of biocrude with approximately 75% of the energy content of fossil crude. While Comstock’s biointermediates can be used in several renewable fuel pathways, Comstock’s grant application is based on the fermentation of cellulosic sugar into lipids, the reaction of lipids with Bioleum to produce a single homogeneous feedstock, and the conversion of this homogeneous feedstock into renewable fuels, at yields in excess of 80 gallons per dry ton of feedstock (on a gasoline gallon equivalent basis).

Comstock’s grant application is supported by a team of collaborators, including Topsoe Inc., Marathon Petroleum Company LP, Novozymes, Xylome Corporation, RenFuel K2B AB, Emerging Fuels Technology Inc., University of Nevada Reno, University of Minnesota Duluth’s Natural Resources Research Institute, and the State University of New York College of Environmental Science and Forestry.

“We are grateful to have the opportunity to collaborate with such an exceptional team of industry leaders,” said Corrado De Gasperis, Executive Chairman and Chief Executive Officer of Comstock. “The combined team enables an extremely valuable ecosystem to advance a new, highly scalable and rapidly replenishable feedstock source for renewable fuels. This ecosystem is capable of making material contributions to neutralizing emissions from mobility in the United States. United and to the goal of net zero emissions by 2050.”
