SunHydrogen, Inc. shared an update to its shareholders from its Chief Executive Officer, Tim Young, as follows. In February 2023, SunHydrogen unveiled the largest version to-date of its nanoparticle-based green hydrogen technology, which splits water molecules into high-purity green hydrogen and oxygen using the sun's energy. This 1.5 sq.

ft. panel houses 16 hydrogen generators and integrates light absorbers, catalysts, membranes, gas collection, and liquid delivery all in one unit. SunHydrogen panel is currently the only self-contained nanoparticle-based hydrogen generation device of its kind that utilizes the sun's energy to split water molecules into high-p purity green hydrogen and oxygen.

Scalable system design, use of low-cost, abundant materials, and ability to utilize water of varying purities are all attributes that set the company apart from conventional electrolyzer solutions. Team's diligent work to scale panel design is a testament to unwavering commitment to providing a truly unique solution that has the potential to revolutionize the green hydrogen landscape and make green hydrogen production highly cost-competitive with brown hydrogen. Team's efforts are currently focused on increasing the panel's hydrogen production rates and durability while decreasing the cost per kilogram of hydrogen produced.

The company is pursuing these goals through a series of improvements to hydrogen panel's design and internal components, and commitment to these efforts is driven by overarching goal of delivering the most affordable green hydrogen solution. First, the company are increasing the hydrogen generator area to panel area ratio by over 50% compared to the current design. This upgrade will result in a substantial increase in the amount of solar energy absorbed and converted into hydrogen gas.

Scientific team is also working closely with the National Renewable Energy Laboratory (NREL) and the University of Iowa to integrate existing, low-cost semiconductors into nanoparticle-based system to substantially improve the overall power conversion efficiency of hydrogen panels. Additionally, are working with industrial partners Corning Laser Technologies GmbH and Geomatec to reduce voltage loss between the anode and cathode catalysts, also resulting in improved power conversion efficiency. Lastly, team is working closely with the Singh Lab at the University of Michigan to optimize catalyst and membrane integration techniques.

This will increase the lifetime of catalyst, decreasing the overall hydrogen production cost. These improvements are currently being implemented and tested in 1.5 sq. ft.

panel, upon which the design will then be translated into a 1 m(2) panel. These advancements have also been designed specifically to increase the lifespan and stability of the panel, reducing the need for maintenance and replacement and making it even more cost-effective for future customers to adopt green hydrogen.
