Carbon Capture Technology: Does It Actually Work at Scale

Carbon capture gets pitched as a climate solution. Here's an honest look at what it can do today.

Carbon capture technology pulls carbon dioxide either directly from the air or from a power plant's exhaust before it's released, then stores it underground or repurposes it industrially.

What's actually proven versus still developing

Capturing carbon directly from a concentrated industrial exhaust stream is well-established and reasonably efficient; capturing it directly from open air is far less efficient and considerably more expensive, since the concentration of carbon dioxide in ordinary air is very low.

The honest scale problem

Current carbon capture facilities worldwide remove a tiny fraction of global emissions, and dramatically scaling up the technology would require enormous amounts of energy and investment, which is why most researchers treat it as one tool among many rather than a standalone climate fix.
