Scientists from the University of Cambridge have developed a new device that is able to take in sunlight, carbon dioxide, and water to form a new carbon-neutral fuel without any outside source of electricity. A team of experts behind the device claims it uses a form of ‘artificial photosynthesis’, the process used by plants to transform sunlight into energy. The device relies on an advanced ‘photosheet’ technology and converts sunlight, carbon dioxide, and water into oxygen and formic acid, a storable fuel. Scientists hope this breakthrough will open the doors toward sustainable and practical solar fuel production in the future.
