SunHydrogen, Inc. shared positive test results from a recent trip to Japan where they collaborated with consultants from the University of Tokyo and visited the Honda R&D facility. They achieved a 9% active-area solar-to-hydrogen efficiency in their 1200cm² hydrogen modules, the highest reported for this size. The company maintained high efficiency even after scaling up tenfold, nearing the 10% efficiency threshold, showing the technology's potential at larger scales. The modules also demonstrated stable efficiency across wide temperature ranges. During the visit to Honda R&D, SunHydrogen observed innovative membrane-free hydrogen and oxygen separation in real-world testing. SunHydrogen aims to further optimize design for higher efficiencies in future modules. The trip provided valuable insights and validation for SunHydrogen's technology in both laboratory and real-world environments, showcasing the potential for cost-effective and green hydrogen production.
