Cavendish Renewable Technologies, based in Melbourne, has unveiled its revolutionary C-Cell electrolyser, designed to revolutionize the production of green hydrogen by addressing key barriers in the industry. The electrolyser, featuring an ultra-thin ceramic membrane electrolyte, offers enhanced oxygen evolution, improved ionic conductivity, and long-term stability at high temperatures. By combining solid oxide and alkaline technologies, the C-Cell boasts increased energy performance, reduced capital and operating costs, and compatibility with various renewable power sources. The CEO, Dr. Aniruddha Kulkarni, emphasizes the elegance of utilizing internally generated heat during electrolysis to reduce electrical energy input significantly. The system operates at 100–150°C without external heat sources, achieving high efficiency and simplifying installation. It also allows for easy integration with solar and wind energy, offering precise load control and voltage flexibility. The C-Cell's modular stack design enables efficient coupling to DC solar power systems and operation during low energy pricing windows, with high-purity hydrogen gas output. Moreover, its membrane-electrode structure opens doors for applications beyond hydrogen production, including flow batteries, fuel cells, and CO2-to-fuels electrolysis. Overall, Cavendish's C-Cell presents a promising solution for advancing green hydrogen technology and expanding its use across various sectors.
