SunHydrogen, the developer of a breakthrough technology to produce renewable H₂ using sunlight and water, has completed a demonstration of its green H₂ technology at the commercially-relevant 1 m² scale.

Over the past year, SunHydrogen has rapidly pursued a new methodology that integrates solar cells from CTF Solar GmbH into the company’s core technology for green H₂ production, enabling faster market entry. SunHydrogen’s innovative design utilizes economical, easily manufacturable PV materials to produce clean H₂ and oxygen from just sunlight and water.

In October 2024, SunHydrogen shared that its 100 cm² H₂ modules – manufactured in collaboration with CTF Solar – demonstrated 10.8% solar-to-H₂ efficiency at the Honda R&D facility in Japan. Since then, the company has been working steadily toward a 1m² proof of concept demonstration. On December 11, 2024, the team successfully demonstrated H₂ production in subfreezing temperatures outside the SunHydrogen laboratory in Coralville, IA.

“With this 1 m² demonstration under our belt, we can begin the site selection process for larger pilot demonstrations,” said SunHydrogen’s Chief Scientific Officer Dr. Syed Mubeen. “Our next steps include continuously improving the technology, incorporating even more cost-effective materials without sacrificing efficiency, and scaling it to 25 m² and larger.”

Also, this year, SunHydrogen secured joint development agreements with Honda R&D Co. and CTF Solar GmbH, joined the Texas Hydrogen Alliance to continue making inroads into the H2 economy, and welcomed new board member David Raney, who is leveraging his transportation and energy regulation expertise to help advance the Company’s mission.

“I’d like to express my gratitude to our shareholders for their continued belief in our vision, along with our industrial partners, vendors, and the local Iowa businesses that have supported our progress,” said SunHydrogen’s CEO Tim Young.

“I would specifically like to thank the team at Honda R&D Co., the University of Iowa, the University of Michigan, Niigata Co., Ltd, and our expert consultants Prof. Kazunari Domen, Dr. Hiroshi Nishiyama, and Dr. Taro Yamada for their invaluable support,” Mr. Young continued. “On behalf of the SunHydrogen team, we wish you all a joyful and prosperous holiday season and we look forward to sharing more updates with you very soon.”
