The article discusses the challenges faced by the global green hydrogen industry, particularly regarding the high water demand for electrolysis and the scarcity of clean water sources. Sinopec, a leading Chinese energy firm, is exploring direct seawater electrolysis systems to produce green hydrogen, aiming to tackle the water scarcity issue. The article highlights Sinopec's efforts in developing chlorine-resistant electrode technology and high-performance electrode plates for seawater electrolysis. Additionally, Cornell University and partner institutions have developed a solar-powered seawater electrolysis system that not only produces green hydrogen but also yields potable water through a distillation process. This innovative approach aims to maximize the efficiency of solar energy usage and reduce waste. The research project achieved a 12.6% solar-to-hydrogen conversion efficiency, showing promising results for sustainable green hydrogen production. Furthermore, the article mentions a collaborative green hydrogen project between France and Egypt, supported by a dedicated desalination facility to provide the water needed for electrolysis, powered by nearby renewable energy sources. The utilization of ocean waves for desalination facilities is also suggested as a potential additional renewable energy source. Overall, the article presents various innovative solutions and collaborations in the green hydrogen industry to address water scarcity concerns and enhance sustainability.
