It is one of the great dilemmas of climate change: We take such comfort from air conditioning that worldwide energy consumption for that purpose has already tripled since 1990. It is on track to grow even faster through mid-century—and assuming fossil-fuel–fired power plants provide the electricity, that could cause enough carbon dioxide emissions to warm the planet by another deadly half-degree Celsius.
A paper published Tuesday in the Nature Communications proposes a partial remedy: Heating, ventilation and air conditioning (or HVAC) systems move a lot of air. They can replace the entire air volume in an office building five or 10 times an hour. Machines that capture carbon dioxide from the atmosphere—a developing fix for climate change—also depend on moving large volumes of air. So why not save energy by tacking the carbon capture machine onto the air conditioner?
This futuristic proposal, from a team led by chemical engineer Roland Dittmeyer at Germany's Karlsruhe Institute of Technology, goes even further. The researchers imagine a system of modular components, powered by renewable energy, that would not just extract carbon dioxide and water from the air. It would also convert them into hydrogen, and then use a multistep chemical process to transform that hydrogen into liquid hydrocarbon fuels. The result: "Personalized, localized and distributed, synthetic oil wells" in buildings or neighborhoods, the authors write. "The envisioned model of 'crowd oil' from solar refineries, akin to 'crowd electricity' from solar panels," would enable people "to take control and collectively manage global warming and climate change, rather than depending on the fossil power industrial behemoths."

Given that the capture of CO2 will require further energy input (potentially carbon producing energy!) to occur, won't this be like cooling your kitchen by leaving the refrigerator door open?

I do that all the time. I go to the Fridge. Open up my robe. And, open the door. It feels MAGNIFICENT! And now they found out, it helps our precious environment. Good to know. So good to know!

Yeah, I don't mind if they want to slap some extra widgets on the air handler. The assumption that air conditioning is going to keep happening is a very valid one though. If it's a choice between me having to sleep in 80+F conditions or the planet, Earth's just fucked.

So they make the assumption that we will keep increasing energy need for HVAC systems, which is a credible statement, tacked on with that this will be powered by coal-power through 2050. That's far less credible. While I am pessimistic that we would've gotten rid of coal by then, I'm optimistic enough to believe that additional energy demand will be provided for in a cleaner way.
Then they lose me altogether stating that their system will suddenly be powered by renewable energy. If in 2050 we're still using coal to power hvac systems, then in 2050 we'll also be using coal to power their system.

Ha ha ha "they" will definitely be still be using HVAC. And coal power or whatever they want.
"You" will be sucking up brown outs and dealing with it like the fucking serf you always were until 150 year ago. The entirety of human history, apart from the briefest period ending shortly, is rulers with immense wealth building golden pyramids and extravagant castles. That is where we are going back to - in your lifetime.
