cSink®: Permanent and Safe Carbon Storage

The most effective and scalable solution for turning atmospheric CO₂ into solid carbon

As global CO levels continue to rise, it is crucial to find sustainable solutions for permanently removing carbon from the atmosphere.

cSink®: Permanent and Safe Carbon Storage

The most effective and scalable solution for turning atmospheric CO₂ into solid carbon

cSink® is our breakthrough solution for permanent CO₂ removal.

Using hydrogen and captured CO₂—the same inputs as for green methanol— the cSink® process produces Sub Zero Carbon Fiber, a clean solid graphite that can be stored or reused.

The cSink®, when integrated with the rest of the Modern Forest, -a large-scale facility designed to capture CO₂ from the atmosphere and turn it into valuable resources like green methanol fuel-, is what enables Sub Zero® Methanol to become the world’s first climate-positive energy carrier.

cSink® Process

BENEFITS

Effective CO₂ Removal

cSink® technology enables efficient removal of CO₂ from the atmosphere, contributing to the reduction of greenhouse gas emissions.

Permanent Storage

CO2 is transformed into solid carbon (graphite) and securely stored, contributing to long-term reduction of atmospheric CO₂ concentration.

Environmental Friendliness

The cSink® process is environmentally friendly, preventing the conversion of CO2 into harmful gases and creating a safe carbon storage.

Scalability

The technology can be deployed on a global scale to address the issue of rising atmospheric CO₂ levels.

Reuse Potential

Solid carbon can be repurposed in various industries, such as manufacturing and construction, providing additional value beyond carbon storage​.

How does the cSink® process work?

By integrating cSink® with other Obrist technologies, such as OBRIST DAC+ and Sub Zero® Methanol, we provide a comprehensive solution for reducing atmospheric CO levels and creating valuable byproducts. This approach is not only scalable but also essential for achieving climate-positive goals and ensuring a sustainable future.

Solid Carbon Storage

Obrist's Direct Air Capture (DAC+) technology captures CO₂ directly from the atmosphere. The captured CO₂ is used as the primary input for the cSink® process​.

Using solar power, water extracted from the air undergoes electrolysis to produce hydrogen (H₂), which is a key ingredient for both Sub Zero® Methanol and cSink® production​.

The captured CO₂ is reacted with hydrogen in a controlled process. Instead of converting the CO₂ into methanol as with Sub Zero® Methanol production, this process results in the formation of solid carbon and water​.

The solid carbon is chemically inert, making it safe for permanent storage. This graphite can either be stored indefinitely or repurposed for industrial applications such as carbon fiber or construction materials​.

Industry

APPLICATIONS

Inert carbon can be stored underground forever or converted into products that will not be burned like:

  • Carbon Black pyrolized debris for tires
  • Clean Black carbon for plastics and paints, coatings and ink
  • Graphite for batteries or metal production
  • Graphite CSPG for Li-Ion batteries 
  • Graphite Fibers for structures, high-tech applications
  • Carbon Nano-Tubes for thermoplastics, composites and adhesives
