- Liquid DAC systems pass the air through a chemical solution, such as a hydroxide solution, that removes the CO2 while returning the remaining air to the environment
- Solid DAC systems use sorbent filters that chemically bind to CO2. When the filters are heated, they release the concentrated CO2, which can be captured for storage or use.

3 startups to draw inspiration from
This week, we identified three startups that we can draw inspiration from: Carbon Engineering, Global Thermostat, and Heirloom.
Global Thermostat is a US-based start-up focused on developing technology solutions for direct air carbon capture. It has a patented technology working with CO2 directly from air or from industry smokestacks. The technology uses residual heat to capture more CO2 than power plants or industrial facilities emit. The captured CO2 has multiple applications such as carbonating beverages.
Heirloom Carbon Technologies is an American start-up that aims to remove 1 billion tons of carbon dioxide using carbon mineralization for a cost-effective direct air capture system. The company’s system deploys carbon dioxide removal at a gigaton-scale that captures and processes atmospheric CO2 and minimizes second-order impacts and reduces extraction, thereby helping in restoring the atmosphere using natural processes.
