Solar-powered device captures carbon dioxide from air to make sustainable fuel

Scientists at the University of Cambridge have created a solar-powered reactor that captures carbon dioxide from the air and turns it into fuel. This device could help power cars, planes, and industries while reducing CO2 levels. The reactor uses sunlight to drive the process, making it more sustainable.

Unlike other carbon capture methods, this reactor does not need fossil fuels or large storage spaces for CO2. Instead, it transforms CO2 into syngas, which is useful in making chemicals and pharmaceuticals. The device is inspired by plants’ natural ability to use sunlight for energy.

The reactor works by collecting CO2 from the air at night. When the sun shines, a chemical reaction powered by solar energy converts the captured CO2 into syngas. A special mirror helps concentrate sunlight, increasing efficiency.

Researchers are now working on turning syngas into liquid fuel. If scaled up, this system could provide a clean alternative to fossil fuels. It could be especially useful in remote locations where fuel is hard to access.

This breakthrough could help reduce greenhouse gases while creating valuable resources. The team is developing a larger version of the reactor and plans to begin testing soon.
