Syntholene Energy Corp Secures Expression of Interest from Icelandair for 250 Million Liters of Synthetic Sustainable Aviation Fuel Over 10 Years

Investor Insight

Syntholene Energy is advancing a proprietary synthetic fuel production platform designed to produce high-performance, low-cost synthetic hydrocarbons using renewable electricity, geothermal heat and captured carbon. Following successful prototype-scale validation in 2022, the company is now operating its Iceland demonstration facility as it plans commercial-scale production capable of serving aviation, transportation, industrial energy and other hard-to-abate fuel markets.

Overview

Syntholene Energy ((TSXV:ESAF,FSE:3DD0, OTC:SYNTF) is a synthetic fuel production company company focused on developing high-performance, low-cost synthetic liquid fuels. The company is commercializing its proprietary Hybrid Thermal Production System, which combines renewable electricity, geothermal heat, water and captured carbon to produce synthetic hydrocarbons that can serve as direct replacements for conventional petroleum-derived fuels.

Unlike many alternative energy solutions that require extensive changes to existing infrastructure, synthetic fuels can be transported, stored and utilized through today’s fuel supply chains. The resulting fuels are molecularly pure, free from many contaminants associated with conventional fuels and compatible with existing engines, turbines, storage systems and transportation infrastructure. Produced using renewable electricity, hydrogen and captured carbon, the fuels can deliver over 90 percent lower lifecycle emissions while maintaining the energy density and performance characteristics required across multiple industries.

At the core of the company’s platform is its Hybrid Thermal Production System, which combines high-temperature solid oxide electrolysis with industrially proven fuel synthesis reactors. By incorporating low-cost thermal energy into critical production stages, Syntholene seeks to reduce electricity consumption, the largest cost component for most eFuel producers. This approach underpins the company’s targeted 70 percent cost advantage relative to competing technologies and supports its objective of producing cost-competitive synthetic fuels at commercial scale.

The technology builds upon advancements in high-temperature electrolysis, including work undertaken at Idaho National Laboratory. Following successful prototype-scale validation in 2022, Syntholene is progressing toward field-scale demonstration in Iceland. The company believes a successful demonstration will support future commercial deployment across a range of synthetic fuel applications.

Market demand for low-emission liquid fuels continues to expand across multiple sectors. Sustainable aviation fuel represents Syntholene’s initial commercial focus, supported by increasing airline decarbonization commitments, regulatory mandates, and fuel-blending requirements. Beyond aviation, the broader global eFuel market is projected to grow from US$8.89 billion in 2024 to more than US$215 billion by 2032, creating opportunities across transportation, shipping, industrial energy, and other sectors that depend on liquid hydrocarbon fuels.

Syntholene’s leadership team combines expertise across climate technology, synthetic fuels, industrial engineering, energy infrastructure, project development and resource industries. Recent additions to the advisory board, including former Shell and Suncor executive Marc Mageau and energy industry veteran HY Lee, further strengthen the company’s capabilities as it advances toward commercialization.

Company Highlights

• Addressing a multi-layered growth opportunity: The company is initially targeting sustainable aviation fuel while developing a technology platform capable of serving a substantially larger global liquid fuels market spanning transportation, industrial energy and other hard-to-electrify sectors.
• Proprietary hybrid thermal production system: Syntholene’s technology integrates high-temperature solid oxide electrolysis with industrially proven fuel synthesis reactors, utilizing both electricity and thermal energy to improve efficiency and reduce production costs.
• Targeting a 70 percent cost advantage: By introducing low-cost thermal energy into critical stages of production, the company aims to produce synthetic fuels at 70 percent lower cost than competing eFuel technologies.
• Pathway to cost-competitive synthetic fuels: The company believes its technology provides a credible pathway toward producing synthetic fuels that can compete economically with conventional petroleum-derived fuels at scale.
• High-performance fuel characteristics: Synthetic fuels are molecularly pure and free from many contaminants associated with conventional fuels, including sulfur, nitrogen and heavy metals, while remaining compatible with existing infrastructure.
• Over 90 percent lower lifecycle emissions: Synthetic fuels produced from renewable electricity, hydrogen and captured carbon can deliver over 90 percent lower lifecycle emissions than conventional alternatives.
• Prototype validation completed: The company’s production process was successfully demonstrated at prototype scale in 2022 and is now operating a world-first geothermally-integrated demonstration facility in Husavik, Iceland.
• Demonstration facility advancing ahead of schedule: The Húsavík, Iceland facility is now operating, with efficiency and technoeconomic results expected in Q4 2026.
• Strategic geothermal platform: The Iceland project benefits from low-cost geothermal electricity, thermal energy, industrial infrastructure, deep-water port access and an existing 200 MW+ regional grid expansion permitting framework.
• Scalable commercial development strategy: Following demonstration, the company intends to advance a 20,000-tonne-per-year commercial facility design and subsequently scale production through facilities ranging from tens to hundreds of megawatts.

Flagship Project

Húsavík Demonstration Facility, Iceland

Syntholene’s flagship project is its geothermal-integrated demonstration facility located in Húsavík, northern Iceland. The facility is designed to validate the integration of geothermal heat, high-temperature solid oxide electrolysis and synthetic fuel production technologies under real-world operating conditions. Construction has advanced six months ahead of schedule, with first operations initiated on June 22nd 20266 and efficiency and technoeconomic results expected in Q4 2026.

The project leverages northern Iceland’s abundant geothermal resources, providing access to both low-cost electricity and high-temperature steam. Unlike intermittent renewable energy sources, geothermal energy offers reliable baseload power and thermal energy that can be utilized continuously throughout the fuel production process. The location also benefits from established industrial infrastructure, a skilled workforce, proximity to a deep-water port and a favorable regulatory environment.

A key objective of the demonstration facility is to validate the company’s thermal integration strategy and confirm that efficiencies achieved during laboratory and prototype testing can be replicated under commercial operating conditions. The facility incorporates Syntholene’s proprietary Thermal Coupling technology, which converts geothermal steam into high-purity industrial steam suitable for use throughout the fuel production process. Management believes this technology is central to achieving the targeted 70 percent cost advantage relative to competing synthetic fuel pathways.

The project also benefits from significant expansion potential. Iceland has completed environmental permitting associated with a 200 MW regional grid expansion, supporting future industrial development in the region. Following a successful demonstration, Syntholene intends to advance a 20,000-tonne-per-year commercial facility design and subsequently scale production through facilities ranging from tens to hundreds of megawatts. Management believes the Húsavík location alone has the potential to support development capable of generating approximately US$500 million in annual revenue.
