SunHydrogen Installs Improved Hydrogen Modules At Austin Pilot with Early Field Performance Consistent with Lab-Validated Modules SunHydrogen, Inc. announced the successful installation of hydrogen modules built with its latest design improvements at its pilot demonstration system at the University of Texas at Austin's Hydrogen ProtoHub. Hydrogen modules measuring 1.92 m² (20.7 ft²), built with SunHydrogen's latest catalyst integration and coating improvements, installed at UT Austin's Hydrogen ProtoHub, demonstrate efficiencies consistent with the Company's lab-validated 100 cm² and 1,200 cm² modules. A larger population of modules with improved absorber layouts now manufactured for upcoming reproducibility and yield testing. During a recent on-site visit to the Austin pilot, the SunHydrogen team expanded the installation with a new set of hydrogen modules, including modules incorporating advances in catalyst integration and coating strategies identified during the pilot's initial commissioning. These improvements were developed specifically to enhance module performance, effectiveness, and consistency as the Company advances toward commercial-scale production. Most significantly, the 1.92 m² modules (16 times larger than lab-scale) built with these latest improvements demonstrated efficiencies consistent with the 100 cm² and 1,200 cm² modules that SunHydrogen has previously validated and tested at its own laboratories and at partner facilities. This alignment between real-world field performance and lab-validated benchmarks is an important indicator that the Company's process improvements translate from controlled laboratory conditions to outdoor operation at scale. Separately, the Company, together with its partner CTF Solar GmbH, has manufactured more than 100 modules incorporating an improved absorber layout that more effectively converts incoming sunlight into usable power, increasing hydrogen production. The catalyst integration and coating strategies refined during the recent Austin installation will subsequently be applied to these modules. Over the coming months, the Company will test this larger population of modules to evaluate reproducibility, manufacturing yield, and performance predictability, critical requirements for scaling to commercial production volumes. Additional improved modules will also be installed at the Austin pilot as part of this effort. To support continued evaluation, the Austin pilot has been extended for an additional six months. The extension will allow SunHydrogen to gather additional real-world operating data on the improved modules and further refine its technology and manufacturing processes. Announcement • Nov 11
SunHydrogen Highlights Strong Momentum at World Hydrogen Technology Expo in Hamburg SunHydrogen, Inc. announced a successful showing at the Hydrogen Technology Expo in Hamburg, Germany. Exhibiting alongside its solar partner CNBM CTF Solar, the company’s booth attracted sustained engagement from industry leaders, potential partners, investors, and students. Live, in-booth technology demonstrations impressed visitors and reinforced SunHydrogen’s core value proposition—producing clean hydrogen directly from sunlight and water, without the need for a separate electrolyzer or water purification system, in a compact, modular format designed for scalability.Across three days in Hamburg, SunHydrogen’s partner network was a frequent topic of conversation, with CNBM CTF Solar and Honda R&D highlighted as key collaborators. Their work with SunHydrogen signaled growing global industry confidence in the company’s approach and underscored the strategic progress made since formalizing these relationships. The company was equally encouraged by the number of SunHydrogen shareholders who visited the booth, reflecting a strong and growing sense of community within the investor base. In addition to advancing commercial discussions, SunHydrogen initiated new pilot demonstration opportunities—including several outside North America—and strengthened connections with potential collaborators, funding partners, and key vendors such as DuPont and Swagelok to support larger-scale, end-to-end hydrogen production planning.Looking ahead, SunHydrogen remains focused on disciplined execution of the initial 30 m² pilot in Austin, Texas; expanding additional pilot deployments; deepening strategic partnerships; and communicating progress with clarity and transparency. The company thanks its partners and shareholders for their continued support and engagement. SunHydrogen looks forward to sharing further updates as it builds on the momentum from Hamburg and forthcoming news from the 30 m² pilot installation in Austin, Texas. Announcement • Aug 12
SunHydrogen, Inc. Achieves Live Demonstration of Commercial-Size Hydrogen Module SunHydrogen, Inc. announced the successful live operation of its 1.92 m2 (20.7 sq. ft.) hydrogen module. Conducted in an open prototype housing, the demonstration marks a pivotal milestone in the company's path toward commercial-scale, renewable hydrogen production. The 1.92m2 hydrogen module, which uses only sunlight and water to produce hydrogen, represents the most advanced version of SunHydrogen's proprietary hydrogen production technology. Engineered to operate independent of the electrical grid, the system integrates solar collection and hydrogen production into a single unit, offering a modular and scalable solution for distributed renewable hydrogen. Building on this milestone, SunHydrogen will next test its 1.92 m2 hydrogen module inside a closed, specially designed proprietary housing unit for continuous operation. In this configuration, hydrogen and oxygen will be extracted continuously while the water is recirculated. Demonstrating continuous, closed-system operation will form the cornerstone of SunHydrogen's upcoming pilot, which is planned to deploy sixteen such hydrogen reactors totaling over 30 m2 of active area at UT Austin's Hydrogen ProtoHub.
