Did Capturing Carbon from the Air Just Get Easier?

"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful. 

"It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything." 

SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..."

Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage. 

"Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial:

 [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages. 
A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree. 
Their research was published this week in the journal Nature. 

And it's also interesting that they're using AI, according to the university's announcement:

Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said. 
Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture. 
"Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."
