The idea of the approach dates back to the 1920s, when German scientists developed a technology to convert carbon monoxide into liquid fuel. Now chemists at the University of California, San Diego said that they have built and demonstrated a prototype device that can capture energy from the sun, convert it to electrical energy and “split” carbon dioxide into carbon monoxide (CO) and oxygen.
The “device” is still deep into the research phase, as the scientists said they still need additional energy for the process to work. But the approach looks promising and considering today’s fuel prices as well as environmental concerns, the idea is likely to get a lot of attention.
Scientists use solar energy to create liquid fuel from greenhouse gas
