UNIST research team develops solar hydrogen production tech

In South Korea, Business Korea reported that a joint research team at the Ulsan National Institute of Science and Technology (UNIST), announced that it has developed a green hydrogen production technology utilizing solar energy. The research team addressed the drawbacks of perovskite solar cells and significantly increased the size of the photoelectrodes by 10,000 times, enhancing the practicality of the technology. Solar hydrogen technology is an ideal green hydrogen production method that utilizes solar energy, the most abundant renewable energy source on Earth, to electrolyze water and obtain hydrogen, according to the report. Dharmesh Hansora, the lead author of the study, stated: “The photoelectrode developed in this study maintained high efficiency even on a large scale. If we focus on on-site validation for the commercialization of green hydrogen production in the future, we can expect solar-based green hydrogen technology to be commercialized before 2030.”
