Syntholene Energy (SYNTF) announced an independent review confirming technical proof-of-performance at its geothermal-powered hydrogen demonstration facility in Húsavík, Iceland. The review measured stack electricity consumption of 34.90 kWh per kilogram of hydrogen across 713 Phase Two high-load hours. Consumption including auxiliary equipment was 38.60 kWh/kg, excluding steam generation and geothermal circulation requirements.
The review found no degradation in stack voltage data or evidence of heat-exchanger fouling or material performance loss. Syntholene's internal analysis showed approximately 60% higher hydrogen output and 10.5% lower system electricity consumption per kilogram in Phase Two versus Phase One. The review identified potential for cost-competitive synthetic aviation fuel under favourable commercial conditions; actual commercial costs remain dependent on engineering, operating conditions and successful scale-up.
Syntholene (SYNTF) engaged Imperial College London researchers through Imperial Consultants to independently review operating data from its Iceland hydrogen demonstration facility. Nigel Brandon will examine the electrolysis system, heat exchanger and supporting equipment. The report is expected to assess electricity use per kilogram of hydrogen, projected commercial-scale efficiency, operating stability and possible equipment degradation. Phase One testing is complete, and Phase Two high-power operations have begun. Syntholene expects the final report before the end of 2026; Imperial Consultants will receive a fixed £27,500 cash fee.
Syntholene also engaged Euroswiss Capital Partners, Outside The Box Capital and Departures Capital for communications support. Their respective agreements cost CAD$60,000 over six months, CAD$150,000 over six months and CAD$20,000 over twelve months. Services cannot begin until the TSX Venture Exchange accepts the engagements.
Syntholene Energy (SYNTF) announced that Research Capital Corporation has initiated independent equity research coverage of the company. This is the first time an external equity research group has published analyst coverage on Syntholene. The initiation report was authored by Greg McLeish, CFA, and is available directly from Research Capital. The company states that any opinions, estimates or forecasts in the report are solely those of Research Capital and have not been endorsed or approved by Syntholene or its management. Syntholene also clarifies that it did not pay Research Capital a fee for initiating coverage and is not responsible for the report’s content, accuracy or timeliness.
Syntholene Energy (SYNTF) has completed Phase One effects testing at its geothermally integrated SOEC demonstration facility in Húsavík, Iceland, and begun Phase Two high-power operations.
Phase One involved extended, sustained operation of the fully integrated system, including the SOEC stack, proprietary Thermal Coupling Heat Exchanger and balance-of-plant equipment. This phase generated a substantial real-world operating dataset to characterize system efficiency, thermal integration, operational stability and other performance metrics relevant to Syntholene’s anticipated commercial architecture.
Phase Two is now focused on sustained operation at or near the facility’s full available power capacity, with data collection on electrical efficiency, hydrogen production, thermal integration, system stability and behavior under higher loads. The company plans to use combined Phase One and Phase Two data for engineering optimization, technoeconomic analysis, commercial-scale project planning and independent third-party validation in the coming months.
KBR (NYSE: KBR) completed an independent technical and economic review of Syntholene's geothermal‑integrated SOEC hydrogen platform, modeling levelized hydrogen costs of about US$1.75/kg in best‑case Iceland scenarios and US$2.10/kg under broader deployment.
The study benchmarks these costs against higher recent European green and fossil hydrogen estimates and outlines key assumptions, potential technical advantages, and project risks.
Syntholene Energy (OTCQB:SYNTF) produced its first 500 kg of green hydrogen at its geothermally integrated SOEC demonstration facility in Húsavík, Iceland, marking completion of commissioning and start of integrated operations.
Initial results show >99.9% purity, stack power use ~33.5 kWh/kg H₂ and system 37.8–40.0 kWh/kg, with continuous testing and independent validation targeted and full effects data publication in Q4 2026.
Syntholene Energy (OTCQB: SYNTF) completed construction of its geothermal-integrated SOEC demonstration facility in Húsavík, Iceland, about six months ahead of schedule and under budget. The plant is Syntholene’s first fully integrated field deployment and has commenced operations-focused effects testing.
The facility aims to demonstrate how integrating geothermal heat with high-temperature electrolysis could lower electricity needs for hydrogen used in synthetic fuel. According to Syntholene, initial efficiency and technoeconomic results are targeted for release as early as Q4 2026.
Syntholene Energy (OTCQB: SYNTF, TSXV: ESAF) appointed former Suncor and Shell executive Marc Mageau to its Advisory Board. Mageau has over 30 years of oil and gas leadership across refining, oil sands operations, logistics, and large-scale industrial asset management.
According to Syntholene, his expertise in refining operations, infrastructure execution, and industrial scale-up is expected to support commercialization of its thermally-integrated synthetic fuel platform and help grow operations from demonstration-scale to commercial production.
Syntholene Energy (OTCQB: SYNTF) reported that construction of its geothermal-integrated synthetic fuel demonstration facility in Húsavík, Iceland is about six months ahead of schedule, with completion and first operations now targeted for June 2026.
Key systems, including the Thermal Coupling heat exchanger and SOEC, were completed early, enabling earlier testing and efficiency and technoeconomic data publication as soon as Q4 2026. A site visit for industry participants and investors is planned in June.
Syntholene Energy (OTCQB: SYNTF) appointed HY Lee to its Advisory Board and named Grant Tanaka, CFO since May 2021, as interim Corporate Secretary effective May 8, 2026. Lee previously led contract management for the US$24.4 billion Barakah Nuclear Energy Plant. Syntholene also outlined details of Robert Rapier’s independent three‑month technical and economic assessment of its thermally integrated electrolysis platform, for which he received a fixed US$6,000 fee.
