Syntholene Accelerates Construction of Demonstration Facility by Six Months, Now Targeting Completion in June 2026
Rapid Execution of Thermal Coupling System and Solid Oxide Electrolyzer Cell Supports Accelerated Operations Timeline
Chicago, IL – May 27, 2026 –Syntholene Energy Corp. (TSXV: ESAF) (OTCQB: SYNTF) (FSE: 3DD0) (“Syntholene” or the “Company”), announced today that the construction of its geothermal-integrated synthetic fuel demonstration facility in Húsavík, Iceland (the “Demonstration Facility”) is ahead of schedule, and that first operations could now occur as soon as June 2026. Effects testing and real-world data gathering are expected to commence shortly thereafter, and the Company is now targeting publication of its first efficiency and technoeconomic data as early as Q4 of 2026.
Dan Sutton, CEO of Syntholene, stated:
Few advanced energy projects finish ahead of schedule, even at the demonstration stage,
“The fact that construction of Syntholene’s Demonstration Facility is on track to finish six months ahead of schedule reflects the seasoned execution capabilities of Syntholene’s engineering and project teams, as well as the elegance and modularity of the Company’s thermal-hybrid architecture.”
The accelerated construction timeline stems from the completion of several key engineering and manufacturing milestones ahead of schedule, including the fabrication of the Demonstration Facility’s Thermal Coupling heat exchanger system in just 42 days. Factory acceptance and operational commissioning of the Company’s solid oxide electrolyzer cell (“SOEC”) system was also completed ahead of the originally scheduled Fall 2026 completion timeline.
The Demonstration Facility has been designed to demonstrate the cost and energy efficiencies of integrating geothermal heat with high-temperature electrolysis for the production of low-cost hydrogen as the core feedstock for synthetic fuel production.
The Company strives to become the first company to demonstrate the integration of geothermal heat with high-temperature electrolysis for synthetic fuel.
The Demonstration Facility is intended to validate continuous operational integration between geothermal heat infrastructure, SOEC hydrogen production, and supporting balance-of-plant systems. Syntholene expects that data generated from the Demonstration Facility will support future engineering optimization, technoeconomic analysis, strategic partnerships, and financing initiatives.
The Company plans to host a site visit at the Demonstration Facility in Norðurþing, Iceland in June for industry and market participants, strategic partners, and investors. Parties interested in attending may contact the Company for additional information regarding timing and participation.
