Syntholene completes design report for demo facility

Executive Summary

• Syntholene Energy Corp. has completed its Conceptual Design Report (CDR) and technoeconomic analysis for a planned geothermal-integrated effect test demonstration facility in Iceland, marking a key technical milestone in its development roadmap.
• The project aims to validate the world's first integration of high-enthalpy geothermal heat with solid oxide electrolyzer cells (SOEC) to produce low-cost, low-emission hydrogen for synthetic hydrocarbon fuels (eFuel).
• The company has achieved the first of three business milestones required to issue deferred consideration shares to former shareholders of Syntholene Energy Corp. (Delaware), triggering the issuance of 1,397,500 shares.

Key Details

• Technical Milestone: Completion of the Conceptual Design Report (CDR) and integrated technoeconomic analysis for the geothermal-integrated effect test demonstration facility.
• Technology Validation: The CDR validates the integration of high-enthalpy geothermal heat with SOEC technology to produce hydrogen, targeting a scalable pathway to hydrogen production below $2 (U.S.) per kilogram, with a long-term objective of below $1 (U.S.) per kg.
• Efficiency Metrics:
  • Conventional low-temperature electrolysis consumes ~65 kWh/kg H2 with 60-70% electrical efficiency.
  • Syntholene’s high-temperature steam electrolysis (SOEC) reduces energy demand to as low as 37 kWh/kg H2, achieving 85-90% electrical-to-hydrogen conversion efficiency when supplied with external process heat.
• Effect Test Objectives: The upcoming effect test in Iceland will validate:
  • Novel direct thermal coupling of geothermal well heat to SOEC modules without intermediary boilers.
  • Stable hydrogen production under dynamic geothermal temperature and pressure conditions.
  • Start-up, shutdown, and perturbation response of the integrated system.
  • Commercial-grade hydrogen flow rate and outlet purity performance.
• Construction Status:
  • Site identified in Iceland; lease negotiations commenced.
  • Permitting applications submitted.
  • Off-site construction and assembly of modular components (heat exchanger system and SOEC modules) underway in Harvard, Ill., Copenhagen, and Los Angeles.
  • Target completion of construction in the fourth quarter of 2026, followed by initiation of the effect test.
• Financial Position: The company believes it has sufficient funds to make significant progress toward assembly of core components and site preparation, though additional financing may be required for full construction and operation.
• Deferred Consideration Shares:
  • Milestone 1 (Achieved): Completion and delivery of the CDR and digital twin. Action: Issuance of 1,397,500 common shares required on Dec. 10, 2026.
  • Milestone 2 (Pending): Completion of a 1,000-hour effect test on or before Dec. 10, 2028. Action: Issuance of 5,052,500 common shares.
  • Milestone 3 (Pending): Award of non-dilutive grants for aggregate gross proceeds of not less than $20-million on or before Dec. 10, 2028. Action: Issuance of 4.3 million common shares.
• Digital Twin: The integration design was validated using a digital twin constructed in Aspen Plus, incorporating mass and energy balances, temperature flow pressure sensitivity analysis, and control logic simulation.

Notable Quotes

• "This CDR validates 20 years worth of work on thermally integrated high-temperature electrolysis, aspiring to produce energy-dense, high-purity synthetic fuel," said John Kutsch, chief engineer of Syntholene.
• "This conceptual design report presents the most detailed current design of Syntholene's demonstration plant in Iceland... Ultimately, it demonstrates our capability to deliver novel production efficiency through our thermal hybrid production process, which we are excited to demonstrate to the world," said Jack Williams, head engineer.
