New Chip-Based Electrochemical Technology Could Fast-Track Clean Fuel and Hydrogen Development

University of Surrey researchers have developed a new “lab-on-a-chip” electrochemical platform that could significantly accelerate the development of renewable-powered carbon conversion technologies, with potential applications spanning sustainable aviation fuel, hydrogen production, advanced batteries, and fuel cells.

The miniature chip-based devices recreate complex electrochemical reactions in a highly controlled environment, enabling scientists to observe chemical processes that were previously difficult to monitor in real time. Powered by renewable electricity, the platform is initially focused on converting captured carbon dioxide (CO₂) into value-added fuels and industrial chemicals such as ethanol and ethylene—an important feedstock for manufacturing.

A key breakthrough lies in the integration of real-time sensing, high-quality experimental data generation, and artificial intelligence-led modelling, allowing researchers to move beyond traditional trial-and-error experimentation. Built-in sensors record electrical signals, reaction conditions, and chemical transformations simultaneously, while AI tools analyze this data to rapidly identify optimal conversion pathways.

“Rising CO₂ emissions are a major driver of climate change, but they also represent an untapped resource. The CO₂ utilisation market is projected to exceed £24 billion by 2030, so the value of these technologies is clear,” said Kai Yang. “Our chip-based devices give us a window into processes that were previously hidden, helping us understand complex chemical systems faster, more clearly and with greater confidence.”

For the clean energy sector, the technology could play a crucial role in accelerating catalyst discovery, improving electrolyser efficiency, and advancing renewable-powered fuel production pathways, reinforcing the growing convergence of AI, electrochemistry, and next-generation decarbonization technologies. The Surrey team is already exploring commercial collaborations in battery materials and energy systems.
