Scientists at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have made significant progress in advancing India's green hydrogen ambitions by designing a next-generation device that produces green hydrogen through a direct photoelectrochemical process using sunlight and earth-abundant materials. Unlike conventional methods, this innovative system eliminates the need for external power supply by using sunlight to trigger water-splitting reactions. The device features a silicon-based photoanode with layers of titanium dioxide, silicon, and nickel oxide, designed for optimal solar-to-hydrogen conversion efficiency. The prototype device achieved impressive performance indicators, showcasing high efficiency and stability over extended operation periods. This development is crucial for India's clean energy objectives under the National Green Hydrogen Mission and Aatmanirbhar Bharat, promoting energy self-reliance and carbon-neutral fuel alternatives. The scalability of this technology is demonstrated through successful testing of a 25 cm² photoanode, indicating potential for commercial hydrogen production. The device's design avoids high-cost catalysts, making it economically viable and compatible with various renewable energy storage systems. The innovative approach taken by the CeNS team has the potential to revolutionize renewable energy systems in India, offering a new pathway to affordable and indigenous green hydrogen at scale. The team is focused on further scaling up the technology, exploring industry partnerships, and integrating the device into existing hydrogen infrastructure, aiming to bolster India's leadership in solar hydrogen technology.
