About Comstock Fuels Corporation

Comstock Fuels Corporation (“Comstock Fuels”) delivers advanced lignocellulosic biomass refining solutions that set industry benchmarks for production of cellulosic ethanol, gasoline, renewable diesel, sustainable aviation fuel (“SAF”), and other renewable Bioleum™ fuels, with extremely low carbon intensity scores of 15 and market-leading yields of up to 140 gallons per dry metric ton of feedstock (on a gasoline gallon equivalent basis, or “GGE”), depending on feedstock, site conditions, and other process parameters. Comstock Fuels additionally holds the exclusive rights to intellectual properties developed by Hexas Biomass Inc. (“Hexas”) for production of purpose grown energy crops in liquid fuels applications with proven yields exceeding 25 to 30 dry metric tons per acre per year. The combination of Comstock Fuels’ high yield Bioleum refining platform and Hexas’ high yield energy crops allows for the production of enough feedstock to produce upwards of 100 barrels of fuel per acre per year, effectively transforming marginal agricultural lands with regenerative practices into perpetual “drop-in sedimentary oilfields” with the potential to dramatically boost regional energy security and rural economies.

Comstock Fuels plans to contribute to domestic energy dominance by directly building, owning, and operating a network of Bioleum Refineries in the U.S. to produce about 200 million barrels of renewable fuel per year by 2035, starting with its planned first 400,000 barrel per year commercial demonstration facility in Oklahoma. Comstock Fuels also licenses its advanced feedstock and refining solutions to third parties for additional production in the U.S. and global markets, including several recently announced and other pending projects.
