SunHydrogen Installs Upgraded 1.92 M² Hydrogen Modules At Austin Pilot Demonstration SunHydrogen announced the installation of upgraded 1.92 m² hydrogen modules at the Company's pilot demonstration system at the University of Texas at Austin's Hydrogen ProtoHub. The newly installed modules incorporate multiple engineering improvements identified during initial outdoor operation, including revised reactor housing designed for inclined operation, improved catalyst integration, enhanced protective coatings, and expanded instrumentation. The upgrades represent the next phase in SunHydrogen's staged pilot program, which is designed to validate module performance while advancing manufacturability and system reliability under real-world operating conditions. The revised reactor housings are designed for operation at an approximately 30° fixed incline, close to Austin's latitude, providing a practical solar-field configuration for evaluating year-round sunlight capture and outdoor performance. The inclined configuration is also designed to support future improvements in gas collection and separation within the reactor housing. Future commercial installations may employ different mounting angles depending on geographic location, site constraints, structural design, and project requirements. Operating upgraded modules alongside earlier-generation units allows SunHydrogen to directly compare performance, durability, and operating characteristics under identical outdoor conditions. The resulting data will guide future module design, manufacturing methods, and system architecture. Temperature remains a key engineering focus of the Austin pilot. While laboratory testing allows temperature and illumination to be tightly controlled, outdoor operation exposes the system to continuously changing sunlight, ambient conditions, and wind throughout the day and across seasons. These temperature variations influence multiple parts of the reactor differently. Higher temperatures generally reduce semiconductor voltage while often improving catalyst reaction kinetics. The objective is therefore not simply to maximize or minimize operating temperature, but rather to enlarge the practical operating window in which the semiconductor absorber, catalysts, protective coatings, gas-management system, and balance-of-system components operate together with maximum efficiency, durability, and reliability. Data collected from the Austin pilot will be used to optimize future reactor designs for long-term outdoor deployment. SunHydrogen has also expanded the instrumentation and monitoring capabilities of the Austin pilot. Enhanced sensing and data-acquisition systems provide greater visibility into reactor performance, including gas composition monitoring to assess hydrogen output under real-world conditions, and enable higher-confidence analysis of long-term outdoor operation. Separately, additional upgraded semiconductor modules produced through SunHydrogen's manufacturing-development program with CTF Solar have arrived at the Company's Iowa facilities. These modules will be used to evaluate manufacturing reproducibility, production yield, and field performance across a larger population of manufactured modules. This evaluation includes the uniformity and repeatability of protective coatings across production runs. The work is intended to demonstrate that recent design improvements can be produced consistently and translated into scalable manufacturing processes. SunHydrogen will continue collecting long-term operating data from the Austin pilot throughout the coming months. Insights from the program will guide the next generation of module design, manufacturing processes, system integration and architecture as the Company advances toward larger-scale field demonstrations and commercial deployment.

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.
