Carbon capture and storage (CCS) and direct air capture (DAC) are both complex industrial processes that isolate CO2 but these newly booming technologies are fundamentally different and often conflated.
Here’s a primer on what they are and how they differ.
What is carbon capture?
CCS siphons off CO2 from the exhaust, or flue gas, of fossil fuel-fired power plants as well as…
