Researchers at the University of Cambridge have developed an innovative floating, solar-powered device capable of transforming contaminated water or seawater into clean hydrogen fuel and purified water globally.

This adaptable device, created by the Cambridge research team, is designed for resource-limited or off-grid environments, working with any open water source without external power.

Inspired by photosynthesis, the device stands out from earlier versions, operating efficiently with polluted or seawater sources while generating clean drinking water simultaneously.

Tests on the device demonstrated its ability to produce clean water from highly polluted sources, as reported in the journal Nature Water.

Co-lead author Dr. Chanon Pornrungroj highlighted the challenge of integrating solar fuels production and water purification in one device, emphasizing the potential of a device that can operate using contaminated water.

The research team, led by Professor Erwin Reisner, developed a design using a nanostructured carbon mesh and a deposited photocatalyst to ensure the device remains functional by floating above the water, preventing contamination interference.

The device optimizes solar energy usage with a white, UV-absorbing layer for hydrogen production, transmitting the remaining solar spectrum to vaporize water.

While still a proof of principle, the researchers believe the device represents a crucial step toward developing solutions for a circular economy and a sustainable future.

The research received support from various programs, including the European Commission's Horizon 2020, The European Research Council, the Cambridge Trust, the Petronas Education Sponsorship Programme, and the Winton Programme for the Physics of Sustainability.
