Alternative Energy Engineers from the University of Delaware developed a method for effectively capturing 99 percent of carbon dioxide from the air using an electrochemical system powered by hydrogen, a press statement reveals. Aside from boosting the overall performance of carbon capture technology, the new method could also enable the commercial production of more sustainable fuel cells. Capturing 99% of CO2 from the air The new system, outlined in a new paper in the journal Nature Energy , was actually born out of a setback in another research project. The team behind the new technology was originally working on hydroxide exchange membrane (HEM) fuel cells, a more affordable and environmentally friendly alternative to traditional acid-based fuel cells. While working on that technology, the team was faced with a serious obstacle. HEM fuel cells, they found, are very sensitive to carbon dioxide in the air, making it hard for the […]
