In July 2024, SunHydrogen announced its technology collaboration agreement with CTF Solar GmbH to integrate CTF’s solar cell modules into SunHydrogen’s technology for green hydrogen production. This approach draws on the core principles of SunHydrogen’s nanoparticle technology while utilising a mature manufacturing platform, enabling faster market entry.
In collaboration with CTF Solar, SunHydrogen has designed scalable thin-film solar cell module architecture that will form the basis for multiple 1 square metre hydrogen panel demonstrations. The company is pleased to share that initial fabrication and testing of these large-scale modules is officially underway. Concurrently, SunHydrogen is working to safeguard the modules from chemical corrosion, ensuring their durability and long-term performance.
The company has also announced its joint development agreement with Honda R&D Co. SunHydrogen’s initial 100 cm² hydrogen modules – designed in collaboration with CTF Solar – have demonstrated 10.8 percent solar-to-hydrogen efficiency while under trial at the Honda R&D facility in Japan. The research team is also studying the effects of various hydrodynamic conditions on the modules, further optimising their performance.
“To our knowledge, this efficiency level has not been reached by any other company using cost-effective semiconductor materials immersed in water” said SunHydrogen’s Chief Scientific Officer Dr. Syed Mubeen. Working with Honda R&D, the SunHydrogen team is also moving to finalise sites for large-scale pilot plant demonstrations.
Additionally, SunHydrogen’s expert collaborators – Prof. Kazunari Domen, Dr. Hiroshi Nishiyama, Dr. Taro Yamada and Dr. Nirala Singh – are developing innovative membraneless housing units for the Company’s hydrogen panels. These units enable safe separation of hydrogen and oxygen without membranes, significantly reducing cost and eliminating the use of environmentally persistent fluorinated compounds (PFAS).
