Comstock Fuels and Emerging Fuels Technology Advance SAF and Other Renewable Fuel Yields

VIRGINIA CITY, Nev., Dec. 23, 2024 (GLOBE NEWSWIRE) -- Comstock Inc. (NYSE: LODE) (“Comstock” and the “Company”) announced today that its wholly-owned subsidiary, Comstock IP Holdings LLC, has executed a Technology Cooperation Agreement (“TCA”) with Oklahoma-based Emerging Fuels Technology, Inc. (“EFT”).

Under this agreement, Comstock and EFT will enter into a Master License Agreement, supported by ongoing EFT technical development, to integrate EFT’s gas-to-liquids process (“GTL” and “EFT Process”) into Comstock’s industry-leading renewable fuel solutions.

The integrated system will be able to capture and convert carbon emissions into “emissions derived renewable fuels” (“EDF”) that further extends Comstock’s industry-leading renewable fuel yields, including SAF. All commercialization of existing and future Comstock Fuels Corporation’s renewable fuel technologies, including those developed through this partnership, will be managed exclusively by Comstock Fuels Corporation. EFT is headquartered and operates in Tulsa, Oklahoma.

David Winsness, president of Comstock Fuels, said, “Ken, Mark and EFT are leading fuel innovators (and producers) and one of our most trusted technical partners and supporters for many, many years, and true leaders in innovating and deploying gas-to-liquids solutions. Integrating the EFT process with our already market leading yields enables a significant increase in our SAF production goals, while further reducing carbon intensities. Extending our system with EFT is a very natural evolution.”

Emissions Derived Fuels

Comstock Fuels delivers advanced lignocellulosic biomass refining solutions that produce market-leading yields of SAF, renewable diesel, cellulosic ethanol, and other renewable fuels at extremely low carbon intensities. Comstock’s process involves: (1) solvolytic digestion and fractionation of lignocellulosic biomass, (2) bioconversion of cellulose into Cellulosic Ethanol, (3) esterification of lignin and other derivatives into Bioleum Oil, (4) hydrodeoxygenation of Bioleum Oil into Hydrodeoxygenated Bioleum Oil (“HBO”), and (5) refining of the resulting intermediates into ASTM compliant fuels. These processes can produce up to 125 gallons of renewable fuel per dry metric ton of feedstock (on a gasoline gallon equivalent basis, or GGE), depending on feedstock, lignin content, site conditions, and other process parameters, with extremely low carbon intensity scores of 15 or even less.

Integrating EFT’s GTL process to convert Comstock’s process emissions has the potential to increase Comstock’s industry leading bulk biomass conversion yields even further, to more than 140 GGE and approximately 70% of the theoretical maximum yield from most forms of woody biomass.

Kenneth Agee, founder and president of EFT, added, “Comstock’s yields and recent progress are extremely impressive. Using woody biomass to produce circular fuels has the potential to make a major contribution to decarbonizing global mobility and this TCA and collaboration with the Comstock team is a great application of our technology for the production of premium synthetic Fischer-Tropsch fuels. We share similar ambitions of accelerating the production of renewable fuels with low or negative carbon intensity on a cost-competitive basis, and we’re excited to get to work.”

Technology Readiness Level

Comstock uses the technology readiness scale to estimate the readiness of technology from conception to commercialization, iterating sequentially as follows: (i) TRL 1 (basic principles observed and reported); (ii) TRL 2 (technology concept and application formulated); (iii) TRL 3 (analytical and experimental proof of concept); (iv) TRL 4 (validation in laboratory environment); (v) TRL 5 (pre-pilot scale validation in relevant environment); (vi) TRL 6 (pilot prototype demonstration in relevant environment); (vii) TRL 7 (scaled-up commercial prototype in operational environment); (viii) TRL 8 (commercial system demonstration); (ix) TRL 9 (commercial maturity).

Comstock’s existing process solutions use TRL 9 components in new ways that have been validated at TRL 6 with plans deployed for elevating to TRL 7 in Comstock’s recently announced 75,000 metric ton per year (“MTPY”) demonstration facility, and from there to TRL 8 in Comstock’s planned 1,000,000 MTPY commercial facilities. The scope of work under Comstock’s planned technical services agreement with EFT involves all engineering and technical support required to build and integrate a modular TRL 7 scale-up of the EFT Process into Comstock’s demonstration facility followed by continued and accelerated scaling to TRL 8 in Comstock’s commercial facilities.

Kevin Kreisler, Comstock’s chief technology officer, concluded, “Process emissions capture and utilization will meaningfully enhance our commercialization impact. Our innovations and engineering teams have designed our processes to maximize quality, yield, throughput, and profitability while relying on robust TRL 9 systems to mitigate scaling risks. Still, upwards of 20% of our feedstock value would otherwise be lost to process emissions. Converting even a portion of those losses into additional yield with EFT’s proven commercial solution enables us to and accelerate the rate that the market adopts our combined offering and produce globally meaningful quantities of new energy.”

About 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 fuels, with extremely low carbon intensity scores of 15 and market-leading yields of up to 125 gallons per dry metric ton of feedstock (on a gasoline gallon equivalent basis, or “GGE”), depending on feedstock, lignin content, site conditions, and other process parameters. Comstock Fuels plans to directly build, own, and operate a network of Bioleum Refineries in the U.S. to refine 50 million tons of biomass annually into 8 billion gallons of renewable fuel by 2035, corresponding to 50% of the U.S. renewable fuel mandate. Comstock Fuels is currently evaluating several U.S. sites for construction of its Demonstration Scale Facility to validate its fully integrated process at 75,000 tons per year, paving the way for rapid full-scale commercialization. Comstock Fuels also licenses its advanced refining solutions to third parties for additional production in the U.S. and global markets, including several recently announced and other pending projects.
