Designed to extract CO₂ directly from the atmosphere, being a key component of the climate-positive energy carrier production plant, The Modern Forest.
OBRIST DAC+ is built for scalability and continuous operation, using widely available, cost-effective materials and operating efficiently even in regions with limited resources. Its low-temperature, low-pressure operations make it particularly suited for deployment in sunbelt regions.
Obrist DAC+ reduces CO₂ concentration greatly from approximately 420 ppm, utilizing sodium hydroxide (NaOH) as the sorbent in a low-energy, continuous operation.
The system operates under low temperatures and pressures, minimizing energy usage and making it viable across various climates and environments.
Obrist DAC recovers water from the air, ensuring self-sufficiency even in arid regions without the need for external water or chemicals, making the system fully operational in a wide range of climates.
The system’s modular design enables flexible deployment, allowing easy expansion to meet CO₂ capture needs in different environments and scales.
By integrating OBRIST DAC+ with the Modern Forest, we provide a scalable, efficient solution for capturing CO₂, producing renewable fuel, and removing excess carbon from the atmosphere. This closed-loop system is designed for a climate-positive future.
Ambient air is transported into a reactor via a fan, where CO₂ reacts with NaOH and water, creating Na₂CO₃ (sodium carbonate), effectively capturing CO₂ from the air.
The sodium carbonate solution is processed through electrolysis. During this step, hydrogen (H₂) and oxygen (O₂) are released, and the sodium carbonate is converted into NaHCO₃ (sodium bicarbonate), ready for further processing.
At a temperature of around 120°C, the NaHCO₃ undergoes thermal decomposition, releasing pure CO₂ and water. The CO₂ is then used to produce Sub Zero® Methanol (green methanol) as well as conversion into solid carbon via our cSink® process for permanent storage.
