Syntholene Energy Corp. Announces Issuance of Key U.S. Patent Covering Proprietary Fuel Synthesis Reactor

Newly granted patent represents a foundational innovation, engineered to deliver high-yield, low-cost, and ultra-pure synthetic fuels, including eSAF

Syntholene Energy Corp. (TSXV: ESAF) (FSE: 3DD0) ("Syntholene" or the "Company") announces the issuance of its first U.S. Patent granted by the United States Patent and Trademark Office (the "USPTO") for the Company's proprietary system for producing high-performance, low-cost, and carbon-neutral synthetic fuels.

This patent, No. US 12,441,674 B2, protects critical intellectual property underlying the Company's novel Compact Cascade Oligomerizer, engineered for high efficiency fuel synthesis performance using the Methanol-to-Jet process. The design is a unitary vessel with multiple chambers incorporated into a single column, as opposed to current proposed systems that use multiple separate and single purpose reactors to produce saturated linear hydrocarbon chains via methanol synthesis, oligomerisation and hydrogenation in sequence.

The newly granted patent, titled "SYSTEM AND METHOD FOR GENERATING SYNTHETIC FUEL," secures Syntholene's rights to a fuel generator and a method for generating fuel in which a Monolithic Block includes a plurality of plates stacked and bonded together. This represents a foundational innovation for delivering high-yield, low-cost, and ultra-pure synthetic fuels, including sustainable aviation fuel (eSAF).

"This patent represents a major milestone for Syntholene as we continue to de-risk and protect our next-generation platform for industrial-scale synthetic fuel production," said Dan Sutton, CEO of Syntholene. "It reinforces our leadership in proprietary, high-efficiency process design, and strengthens our commercial moat as we continue to refine our process components and enhance the efficiency of our integrated supply chain."

"We are proud that the USPTO has recognized this novel approach to high level integration of discrete systems into an efficient unitary solution." Said Syntholene Chief Engineer John Kutsch. "This patent represents Syntholene's unique process intensification approach to high-efficiency systems integration."

This intellectual property covers core reactor architecture and process integration within the Company's integrated fuel synthesis systems. It describes a key technology designed to maximize fuel yield and product purity from syngas inputs while minimizing unwanted byproducts typical in legacy fuel synthesis reactor systems, and employs the physical proximity of exothermic and endothermic reactions within the same unit to maximize heat integration and utilization.

Syntholene continues to pursue patent protection across North America, Europe, and Asia to secure its differentiated IP position ahead of commercial-scale deployments.

About Syntholene

Syntholene is actively commercializing a new production pathway for low-cost clean fuel synthesis. The target output is ultrapure synthetic jet fuel, manufactured at 70% lower cost than the nearest competing technology. The Company's mission is to deliver the world's first truly high-performance, low-cost, and carbon-neutral synthetic fuel at an industrial scale.

Founded by experienced operators across advanced energy infrastructure, nuclear technology, low-emissions steel refining, process engineering, and capital markets, Syntholene aims to be the first team to deliver a scalable modular production platform for cost-competitive synthetic fuel, thus accelerating the commercialization of carbon-neutral efuels across global markets.
