Syntholene Energy Corp. Announces Completion of Conceptual Design Report and Technoeconomic Analysis

Executive Summary

• Syntholene Energy Corp. announced the completion of its Conceptual Design Report (CDR) and integrated techno‑economic analysis for a world‑first geothermal‑integrated solid oxide electrolyzer cell (SOEC) effects test facility.
• The design targets hydrogen production costs below US $2/kg (with a long‑term goal of sub‑US $1/kg), potentially enabling cost‑competitive synthetic aviation fuel (eSAF).
• Achievement of the CDR milestone triggers issuance of 1,397,500 deferred consideration shares and marks a key step toward field deployment in Iceland, slated for Q4 2026.

Key Details

• Project Scope: Demonstration of direct thermal coupling between high‑enthalpy geothermal steam (~150 °C) and SOEC modules to produce low‑cost, low‑emission hydrogen for synthetic hydrocarbon fuels.
• Technical Highlights:
• High‑temperature steam electrolysis (HTSE) reduces energy demand to ≈37 kWh/kg H₂ versus ~65 kWh/kg for low‑temp electrolysis.
• Expected electrical‑to‑hydrogen conversion efficiency of 85–90 % when supplied with process heat.
• Novel direct geothermal‑to‑SOEC coupling eliminates intermediate boilers.
• Techno‑economic Findings:
• Modeled pathway to hydrogen production < US $2/kg, with potential optimization toward < US $1/kg at scale.
• Cost advantage derived from abundant, low‑cost geothermal heat.
• Construction Progress (Iceland Facility):
• Project management firm engaged; general contractor discussions underway.
• Site identified, lease negotiations and permitting applications submitted.
• Off‑site fabrication of heat exchangers and SOEC modules ongoing in Harvard, IL; Copenhagen; Los Angeles.
• Targeted completion of the demonstration facility Q4 2026; effects test to follow.
• Funding Outlook: Company believes current funds are sufficient for significant component assembly and site preparation but may require additional financing to complete construction and operate the Effects Test.
• Deferred Consideration Shares (Milestone‑Based Issuance):
• 1,397,500 shares issued on Dec 10 2026 for CDR completion (first milestone).
• Additional 5,052,500 shares upon achieving a 1,000‑hour effects test by Dec 10 2028.
• Further 4,300,000 shares upon securing non‑dilutive grants ≥ US $20 M by Dec 10 2028.
• Strategic Implications: Successful validation could position Syntholene as the first company to commercialize geothermal‑SOEC integration, delivering synthetic jet fuel at substantially lower cost than competing technologies and fossil fuels.
