Direct Air Carbon Capture (DACC) is a carbon removal technology, which is a necessary climate change solution. Carbon removal allows us to remove past green house gas emissions from our atmosphere. There are different forms of DACC.

One of the main differences is the "swing," the catalyst that switches the chemical sorbents from absorption to release of CO2. This is an illustration of a moisture or humidity swing DACC machine that captures CO2 when dry and releases it when wet.
