OBRIST DAC+ : Direct Air Capture Technology

Efficient, scalable carbon capture technology

Designed to extract CO directly from the atmosphere, being a key component of the climate-positive energy carrier production plant, The Modern Forest.

Obrist DAC+: Advanced Technology for Direct CO₂ Capture

Efficient, scalable carbon capture technology

This technology enables the production of Sub Zero® Methanol, a renewable e-methanol based energy carrier, while ensuring permanent CO storage transforming excess CO into solid clean carbon (cSink®).

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.

Technology

BENEFITS

High CO₂ Capture Efficiency

Obrist DAC+ reduces CO concentration greatly from approximately 420 ppm, utilizing sodium hydroxide (NaOH) as the sorbent in a low-energy, continuous operation.

Low-Temperature & Pressure Operation

The system operates under low temperatures and pressures, minimizing energy usage and making it viable across various climates and environments.

Water Recovery

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.

Modular & Scalable Design

The system’s modular design enables flexible deployment, allowing easy expansion to meet CO capture needs in different environments and scales.

Integration in the Modern Forest

By integrating OBRIST DAC+ with the Modern Forest, we provide a scalable, efficient solution for capturing CO, producing renewable fuel, and removing excess carbon from the atmosphere. This closed-loop system is designed for a climate-positive future.

PROCESS

Step 1: CO₂ Capture from the Air
Step 2: Electrochemical Conversion
Step 3: Thermal Decomposition of NaHCO₃

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.
