Periodic Reporting for period 1 - C-DAC (Direct Air Capture for on-site CO2 utilization in greenhouses)
Periodo di rendicontazione: 2024-03-01 al 2025-02-28
Climate change is driven by excessive CO2 accumulation in the atmosphere, yet CO2 is also a valuable industrial resource. Over 230 million tons of fossil-based CO2 are consumed annually in industries like agriculture, food preservation, and fertilizers. However, the cost of liquefied CO2 has doubled in recent years, exposing vulnerabilities in traditional supply chains.
Why rely on fossil-based CO2 when we can extract it from the air? The challenge lies in its low atmospheric concentration—just 0.04%—making capture difficult and costly. CARBOMINER has developed C-DAC, an innovative Direct Air Capture (DAC) technology that selectively binds CO2 from ambient air in a fully electric, cost-effective process. Unlike conventional DAC methods, our breakthrough solution combines dry and wet absorbent methods for CO2 capture with a patented electrochemical pH-swing technology for CO2 regeneration. This enables sustainable, scalable, and affordable CO2 supply.
C-DAC has already been demonstrated on-site at client facilities, providing a fossil-free alternative to conventional CO2 sources. By decentralizing supply and reducing dependency on volatile fossil-based CO2, our technology supports climate change mitigation while enhancing food security and industrial resilience.
Our vision is to transform CO2 from an environmental liability into a sustainable feedstock, fostering a circular CO2 economy. By bridging climate action with industrial demand, CARBOMINER’s solution contributes to global decarbonization efforts, strengthens energy security, and establishes a commercially viable model for sustainable CO2 utilization.
