Professors Christopher Jones and Matthew Realff work with Lively on the full spectrum of DAC, from the molecular to the systems level.ĭAC systems use heat to release CO 2 from saturated filter materials. The study's co-authors include researchers in ChBE who've positioned Georgia Tech as a leader in direct air capture technology. They and found the system could capture CO 2 for $150 to $200 per ton - significantly less than commercial systems under construction that are estimated to capture carbon for $300 to $600 per ton. Since all the components of our system are commercially available and fabrication is relatively easy, there should be few technical hurdles to making the module in large scale."Īt least in theory, the team has done that scale-up, using their experimental data to project the economics of a practical system. Now it's important to scale up the module. "We already successfully captured ambient CO 2 with our lab-scale module. "This work not only conceptualized a new generation of DAC systems but also showed practical operations of our invention to some extent," said Won Hee Lee, the paper's first author and a former postdoctoral scholar in Lively's lab. They described their design and approach in the June 21 issue of the journal Joule. They found they could produce carbon dioxide with sufficient purity for underground sequestration and eliminate many of the substantial upfront costs of building typical DAC systems. With the pneumatic tube-inspired modules in place, the team began testing their system. "That's pretty much what we did, and it worked." "There are not many times you have a light bulb moment in your career, but I saw the tubes and I realized, we could put the fibers in something like a bank teller tube canister. DeLoach Professor in Georgia Tech's School of Chemical and Biomolecular Engineering (ChBE). ![]() They had the old pneumatic tubes that come down to transport documents," said Ryan Lively, Thomas C. "I had to go deposit a check at the bank, and I went through the drive-through. And the carbon fiber strands could be quickly heated to release the captured carbon dioxide with minimal heat loss, boosting efficiency.īut they were struggling with how to deploy these new sorbent-coated carbon fibers for maximum effect. That would eliminate the loud fans used in many systems. Their approach used ambient wind flow to draw air across a new kind of coated carbon fiber to grab CO 2. ![]() ![]() Georgia Tech researchers had been working on an idea to simplify traditional direct air capture (DAC) systems. ![]()
