Syntholene Energy Selects Dynelectro, Developer of "World's Most Efficient Electrolyzer" as Vendor for Synthetic Fuel Demonstration Facility

Relationship Represents Potential Long Term Scalability of High Efficiency Supply Chain from Demonstration to Commercial Scale

SYNTHOLENE ENERGY CORP (FSE: 3DD0) (OTCQB: SYNTF) ("Syntholene" or the "Company") announces that it has selected Dynelectro ApS (Denmark) as the electrolyzer technology vendor for its planned synthetic fuel demonstration facility in Iceland. Dynelectro is the developer of what it describes as the world's most efficient electrolyzer platform, purpose-built for high-performance hydrogen production in power-to-liquids applications for synthetic fuel ("eFuel") and, more specifically, synthetic sustainable aviation fuel ("eSAF").

Dynelectro's electrolyzer platform has demonstrated industry-leading energy efficiency in the production of hydrogen, a key feedstock to eFuels, while maintaining durability under continuous industrial operation at variable load. The system architecture emphasizes reduced balance-of-plant complexity, high current density operation, and modular deployment, characteristics that align closely with Syntholene's objective of developing capital-efficient, repeatable synthetic fuel infrastructure.

The planned demonstration facility is intended to validate the Company's integrated approach to producing low-cost hydrogen as a feedstock to eSAF and other eFuels, with a focus on scalability, energy efficiency, and long-term cost competitiveness with fossil fuels.

"Syntholene's eSAF production plans are a perfect match for Dynelectro's electrolyser solution," explains Sune Lilbaek, CEO at Dynelectro ApS. "To be successful in the eSAF market, the lowest possible cost of hydrogen over the lifespan of the plant is a necessity. Dynelectro's unique take on SOEC electrolysers seeks to enable the lowest possible energy consumption and maintenance cost. When integrated with Syntholene's proprietary hybrid thermal production system, it is possible to convert up to 90% of the renewable electrical energy supplied into clean hydrogen. Together, we expect to be deploying the most cost-effective, energy-efficient solution for production of sustainable aviation fuel on the market today."

The vendor selection represents a key technical milestone for Syntholene as it advances engineering and procurement activities associated with its first demonstration-scale facility.

"The selection of Dynelectro is the result of a rigorous two-year technical and commercial evaluation process across all major vendors focused on efficiency, reliability, and long-term scalability," said Dan Sutton, CEO of Syntholene. "Electrolyzer performance coupled with low-cost clean energy are the primary drivers of synthetic fuel economics. Partnering with a technology provider that prioritizes energy efficiency and industrial robustness is critical as we move from demonstration toward multi-megawatt commercial deployment."

About Syntholene

Syntholene is actively commercializing its novel Hybrid Thermal Production System for low-cost clean fuel synthesis. The target output is ultrapure synthetic jet fuel, manufactured at 70% lower cost than the nearest competing technology today. 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, unlocking the potential to produce clean synthetic fuel at lower cost than fossil fuels, for the first time.

Syntholene's power-to-liquid strategy harnesses thermal energy to power proprietary integrations of hydrogen production and fuel synthesis. Syntholene has secured 20MW of dedicated energy to support the Company's upcoming demonstration facility and commercial scale-up.

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.
