Direct Air Capture for on-site CO2 utilization in greenhouses

Introduction

CO2 is recognized as the main pollutant responsible for global warming. On the other hand, 230Mt fossil-based CO2 is consumed globally as feedstock for different industries, including greenhouses, fertilizers, carbonated drinks, and food preservation.

Market Context

With volatile and soaring prices of liquified CO2, raising 10x last year (from €200 to €2,000/t), why don't we take it back from the atmosphere and use it as a valuable feedstock?

Challenges of CO2 Capture

Although high enough to cause climate change, atmospheric CO2 concentration makes up just 0.04% of the air we breathe, which is low enough to make it tricky to capture cost-efficiently.

Technology Overview

CARBOMINER has developed C-DAC as a novel Direct Air Capture technology for selective CO2 binding from the open air in a fully electric and cost-effective process.

Technical Details

• Based on wet absorbent fiber for CO2 capture
• Patent pending BPM electrodialysis pH-swing for CO2 regeneration

Demonstration and Impact

C-DAC has been demonstrated in greenhouses to provide low-cost fossil-free CO2 compared to current CO2 supply options.
