What is Direct Air Capture & storage?

When we talk about Direct Air Capture (DAC), we only speak about the capturing of atmospheric CO₂.

When we use the term Direct Air Capture and Storage (DAC+S), we refer to the capturing of atmospheric CO₂ with its permanent storage to produce negative emissions.

It involves two main steps:

1. Carbon dioxide is captured from ambient air via direct air capture technology
2. The air-captured CO₂ is permanently stored for thousands of years, for example via underground mineralization.
