Syntholene Energy Corp. announced that it has successfully completed Phase One of effects testing at its geothermally-integrated Solid Oxide Electrolyzer Cell demonstration facility in Husavik, Iceland, and has now moved into high-power Phase Two operations. Phase One focused on sustained operation and data collection across the facility's integrated electrolyzer, the company's proprietary Thermal Coupling Heat Exchanger, and balance-of-plant systems, generating an operating dataset used to evaluate efficiency, thermal integration and operational stability relevant to its planned commercial architecture. According to chief executive Dan Sutton, that phase produced novel real-world data characterizing the system's performance, and the focus now shifts to running the facility at or near full available power capacity to gather a second dataset at higher loads. The company expects Phase Two to yield further data on electrical efficiency, hydrogen production, thermal integration and system stability, which together with the Phase One results are intended to inform engineering optimization, technoeconomic analysis and commercial-scale development. Syntholene, which says it operates the world's first geothermally-integrated high-temperature electrolysis facility and is producing hydrogen at 99.99 percent purity, is ultimately targeting ultrapure synthetic jet fuel at significantly lower cost than competing technologies, and plans to submit its testing data for independent third-party validation...
