La Direct Air Capture (DAC) is the capture of carbon dioxide (CO₂) directly from the air. This technique uses solid or liquid compounds and their ability to selectively bind CO₂. Once the greenhouse gas is trapped, the DAC material can either be stored long-term or regenerated; in this case, concentrated CO₂ is released and the DAC material returns to capturing additional carbon dioxide.

​

Carbon dioxide is a ubiquitous gas in our atmosphere; however, its concentration relative to other gases such as oxygen or nitrogen is much lower. In fact, for every cubic meter of air, only about half a liter is CO₂ (corresponding to 427 parts per million, ppm, concentration). Although low, this concentration is sufficient to drive the greenhouse effect, leading to an average increase in Earth’s temperature of about 1°C for every 100 ppm increase in CO₂ concentration. DAC plays a fundamental role in the fight against the climate crisis due to its ability to be deployed anywhere and to recover already-emitted CO₂. To date, this technology is the only one that offers a renewable source of carbon without quantitative limits, but it has a fundamental drawback: it is too expensive.

​

When CO₂ capture is spontaneous, its release requires energy to separate the capture material and obtain concentrated carbon dioxide for storage or utilization. The limitation lies in the need for large amounts of thermal or electrical energy, which drives the final cost of DAC-derived CO₂ to over 1000 dollars per ton.

 

From here begins our revolution!

​

RAPCO₂ has finally made DAC economically viable by developing a method for regenerating DAC materials through the action of natural microorganisms that, when fed with green hydrogen, actively extract CO₂ and convert it into renewable chemicals, effectively reducing the cost of CO₂ capture to near zero.

Why do they do it so cheaply?

​

Because for them, using CO₂ is the only way to survive, and this makes it advantageous for them to consume CO₂ from DAC and combine it with green hydrogen to produce chemical compounds at high concentrations, all within a fermenter that requires no high temperatures, sterilization, or microbial selection—everything is spontaneous, fast, and safe.
