We’ve heard from space technology companies interested in using the device on space stations to remove the carbon dioxide astronauts exhale.” ![]() “We could, for example, pull carbon dioxide from the atmosphere and continuously inject that concentrated gas into a greenhouse to stimulate plant growth. "The technology can be scaled up to industrial settings-power plants, chemical plants-but the great thing about it is that it allows for small-scale use as well: I can even use it in my office,” Wang says in the statement. And it only requires a simple power source. It does not create or consume chemicals, nor does it need to be heated up or pressurized, according to Wang. In the Wang lab's method, the small reactor can continuously remove carbon dioxide from a simulated flue gas with nearly 100 percent efficiency, generating between 10 to 25 liters of high-purity carbon using only the power of a standard lightbulb, according to a statement from Rice. The process also often requires large-scale infrastructure. Traditionally, carbon capture requires very energy intensive processes that need high temperatures and for the carbon that's been captured to be regenerated. The findings were shared in a study published in Nature last month. The new technology developed in the lab of chemical and biomolecular engineer Haotian Wang, the William Marsh Rice Trustee Chair and an associate professor at Rice, uses electricity to remove carbon dioxide from air capture to induce a water-and-oxygen-based electrochemical reaction. ![]() A Rice University lab has developed an efficient, scalable way to capture carbon dioxide - and it just needs to be plugged into a power outlet to work.
