I came across the 2013 paper "The thermodynamics of direct air capture of carbon dioxide" by Klaus Lackner https://www.sciencedirect.com/science/article/abs/pii/S0360544212006901. It describes the theoretical minimum energy needed to separate CO2 from the surrounding air. One interesting takeaway is that it is energetically less costly to "skim" CO2 from the air (capture a small fraction of the CO2 in the air and then moving on to more fresh air). This means that direct air capture is not necessarily much more energy intensive than scrubbing exhaust from smokestacks. In the scrubbing use case, you want to get all the CO2 before adding the exhaust to the atmosphere.

DAC doesn’t scale on chemistry. It scales on power.

West Texas: 500 MW solar ↔ STRATOS (500k t/yr). The question: can carbon removal scale without cannibalizing clean electricity?

The world's largest Direct Air Capture plant just got its own 500MW solar farm. ☀️

Origis Energy's Swift Air Solar complex in Texas is now fully online — dedicated renewable power for Occidental's STRATOS DAC facility.

DAC powered by fossil fuels never made sense. This is how it should work.

Climeworks just opened a new HQ in Calgary, Alberta 🇨🇦

Why it matters: They're setting up cold-weather DAC testing — building on Iceland experience to prove the tech works in harsh Canadian winters.

Commercial plant ambitions to follow. DAC is going global. 🌍

A new model for climate-positive buildings.

Imagine circular architecture designed not just for aesthetics — but for atmospheric impact. Buildings can become active carbon removal systems, integrating biological Direct Air Capture directly into facades and structures.

At Carbelim, we transform infrastructure into carbon-negative assets using microalgae-powered solutions.

The Data Center vs. the Planet: Big Tech’s Land-Grab in Durable Carbon Removal - ClimateTech Industry Examiner

As AI data centers drive up emissions and power demand, Big Tech is racing to lock in “durable” carbon removal credits—sending prices soaring, squeezing other

Das Ausfiltern von CO2 aus der Atmosphäre (DAC) und dessen Nutzung als Rohstoff (CCU) würde große Energiemengen erfordern. Zudem müssen die dazu erforderlichen technischen Anlagen enorme Mengen an Entropie in die Umwelt exportieren. DAC und CCU sind somit nicht nachhaltig. Statt DAC und CCU können und müssen natürliche Ökosysteme zu einer erhöhten #CO2Speicherung beitragen.
