U.S. Researchers Test Sunlight-Powered Technology to Capture Carbon From Air
Published by Todd Bush on November 9, 2026
Washington, Nov. 9 (SANA) U.S. researchers are testing a new technology that uses sunlight and special dyes to remove carbon dioxide from the atmosphere, aiming to reduce the high energy costs associated with conventional carbon capture methods.
Alex Gagnon and Julian Sachs of the University of Washington developed the concept while studying pollution’s impact on coral reefs in the Pacific Ocean, CNN reported Monday.

The researchers founded Banyu Carbon to develop the technology, which uses a water-based solution containing special dyes to absorb carbon dioxide from the air. Sunlight is then used to release the captured gas, allowing it to be stored or used in industrial processes.
The approach could reduce energy consumption compared with existing direct air capture systems, some of which require substantial electricity to separate carbon dioxide from the atmosphere.
The technology is currently being tested in Australia, with the company aiming to expand its use by 2030.
The project comes as the carbon removal industry faces mounting challenges from high operating costs and declining investment.
The research behind the technology originated from studies of coral reefs on Tetiaroa, an island north of Tahiti.
