According to The Intergovernmental Panel on Climate Change and effectively all climate models, achieving only a rapid reduction in CO2 emissions will not limit global warming to the targeted 1.5°C above pre-industrial temperatures. We will also need to remove between 1.3–29 Gigatons of CO2 from the atmosphere annually by 2050, an objective known as Carbon Dioxide Removal (CDR).
CDR can be achieved through a range of techniques that draw down atmospheric CO2 and send it to long-term storage. Direct Air Capture and Storage (DACCS) techniques are currently the focus of many efforts. In the last 18 months, dozens of new DACCS companies have been formed and are moving towards commercialization, while the US government has introduced significant new tax credits and grant-based funding programs for DACCS.
It is critical that developments and improvements for a range of DAC technologies are rapidly expedited this decade.
In direct air capture (DAC), CO2 is…
