SunHydrogen Achieves Highest Known Efficiency for a Large-Area Hydrogen Module
SunHydrogen (OTCQB: HYSR) has announced significant test results from its recent collaboration in Japan. The company's 1200cm² hydrogen modules, manufactured with CTF Solar, achieved a 9% active-area solar-to-hydrogen efficiency during testing at the University of Tokyo - marking the highest reported efficiency for a hydrogen module of this size.
The modules demonstrated stable performance across temperatures from 5°C to 40°C. This achievement follows previous testing at Honda R&D where 100cm² modules exceeded 10% efficiency, showing minimal efficiency loss despite a tenfold scale increase. Testing was conducted using a state-of-the-art LED solar simulator capable of testing large-scale modules.
Additionally, the company visited Honda R&D in Tochigi, Japan, where they observed rooftop testing of 100cm² modules using an innovative membrane-free hydrogen and oxygen separation system. Honda will soon begin testing the larger 1200cm² modules under similar on-sun conditions.

CORALVILLE, IA , Feb. 05, 2025 (GLOBE NEWSWIRE) -- SunHydrogen, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today shared strong test results from a recent trip to Japan where members of the SunHydrogen team collaborated with consultants Prof. Kazunari Domen, Dr. Hiroshi Nishiyama and Dr. Taro Yamada at the University of Tokyo and visited the Honda R&D facility in Tochigi.
Breakthrough in Large Area Solar-to-Hydrogen Efficiency
At Prof. Domen’s laboratory at the University of Tokyo, SunHydrogen conducted large-area solar testing of its 1200cm² hydrogen modules, manufactured in collaboration with CTF Solar, that comprised the Company’s recent 1m² demonstration system.
SunHydrogen is pleased to report that the 1200cm² modules demonstrated an active-area solar-to-hydrogen efficiency of
Previously, SunHydrogen validated an efficiency exceeding
Additionally, the modules were tested under wide temperatures, ranging from 5°C to 40°C and their efficiency remained stable across the full temperature range. The team utilized a state-of-the-art LED solar simulator, uniquely capable of simulating the solar spectrum over a large enough area to test modules of this scale.
“Scaling up tenfold presents unique challenges, and we are extremely pleased to have maintained such high efficiency in our first large-area test. To our knowledge, this remains the highest reported efficiency for a hydrogen module of this scale,” said SunHydrogen’s CEO Tim Young.
“These results give us confidence that with further design optimization, including maximizing active water-splitting area and refining catalyst loading, we can push efficiencies to
Advancing Real-World Testing with Honda
Following its laboratory testing at the University of Tokyo, the SunHydrogen team visited its joint development partners at Honda R&D in Tochigi, Japan. At their facilities, the team observed on-sun rooftop testing of SunHydrogen’s 100cm² hydrogen modules.
“We were particularly impressed by Honda’s innovative housing unit design, which enables hydrogen and oxygen separation without the use of membranes – a first-of-its-kind approach – and we will continue ongoing testing of the 100cm² modules,” Dr. Mubeen said.
Honda will soon test SunHydrogen’s 1200cm² modules under on-sun conditions using a similar rooftop setup, and SunHydrogen is eager to utilize the performance data from these extended tests to further refine its module design.
“Our visit to Japan provided valuable insights and key validation for SunHydrogen’s technology in both controlled laboratory conditions and real-world outdoor environments,” Mr. Young said. “The University of Tokyo’s unique solar simulator enabled the most comprehensive and precise efficiency testing of our large-area modules to date, while Honda’s membrane-free separation approach represents a significant milestone in real-world implementation. We extend our sincere gratitude to the entire Honda R&D team under the leadership of Mr. Yuichi Matsuo, as well as to Prof. Domen, Dr. Yamada and Dr. Nishiyama.”
