Engineers in the US have demonstrated a way to effectively capture 99 per cent of carbon dioxide from the air using a novel electrochemical system powered by hydrogen.
According to its developers at the University of Delaware, the “game-changing” technology is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to market.
Professor Yushan Yan, chair of chemical and biomolecular engineering, has been working for some time to improve hydroxide exchange membrane (HEM) fuel cells, an economical and environmentally friendly alternative to traditional acid-based fuel cells used today.
But the reason HEM fuels cells aren’t on the road as of late is because they are sensitive to carbon dioxide in the air. This defect quickly reduces the fuel…
