A Melbourne-based clean-tech developer, Cavendish Renewable Technologies Pty Ltd (CRT), has announced the launch of its groundbreaking C-Cell electrolyzer. This technology is a next-generation electrolysis platform that fuses the strengths of solid oxide and alkaline technologies. The C-Cell is expected to be a revolutionary step in electrochemical engineering due to its design, which is expected to enable it to overcome the costs, complexity, and scale-up issues associated with producing green hydrogen. In combination with its modular structure and original hybrid solution, the C-Cell is likely to achieve this by offering high efficiency in producing hydrogen, utilizing an economically and technically compelling approach that enables commercially feasible deployment of this technology.

The core of this novel platform is a uniquely thin ceramic membrane that integrates an equivalent component of the system to work optimally within moderate temperatures (100150 o C) without making use of external heating sources. The output is a high-quality, scaled solution that is reliable at real-world current densities. This allows for operating in pressurized environments and reduces the demands on balance-of-plant systems. This technology further clears the way for a new generation of electrolyzer systems, specifically designed to operate in synergy with renewable electricity and can function within intermittent periods of supply at high and stable efficiencies with long lifetimes. Furthermore, with the global market paying increasing attention to green hydrogen, solutions like C-Cell offer the practicality, flexibility, and scalability to ensure that hydrogen remains a key component of decarbonization.

Executive's Statement

Dr. Aniruddha Kulkarni, CEO, Cavendish Renewable Technologies

“A lot of solutions have been proposed in the green hydrogen space, but very few deliver where it truly matters—on both performance and cost. With C-Cell, we’re not proposing anything that contradicts the laws of thermodynamics or depends on speculative science. It’s a simply elegant way of utilizing internally generated heat during electrolysis to significantly reduce electrical energy input—without needing any external thermal source. That said, if low-grade external heat is available, our modeling indicates the efficiency could be improved even further. We aim to validate this through upcoming trials. What makes this particularly remarkable is that comparable performance has only been achievable with solid oxide electrolysis systems operating above 800°C—a range that introduces significant challenges related to heat integration and long-term material stability, which the industry has yet to reliably solve. C-Cell delivers similar benefits at a fraction of the temperature, with far greater practicality and scalability.”
