DAC Air CO2 Direct Capture Technology

Product Overview

DAC (Direct Air Capture) technology has been validated in China since 2018. It uses solid amine-based carbon capture materials and a modular design to efficiently capture CO₂ directly from ambient air.

The captured CO₂ can be supplied to greenhouses as a carbon fertilizer, improving crop quality and yield, while supporting low-carbon, environmentally friendly agriculture.

Working Principle

The technology relies on the selective adsorption of CO₂ from air using solid amine materials. Air passes over the adsorbent, which captures CO₂.

Once the material becomes saturated, CO₂ is released and recovered through changes in temperature or pressure. The modular design allows flexible configuration to suit capacity needs, from tens of tons to over 10,000 tons per year. This ensures continuous operation and efficient extraction of CO₂ for agricultural or industrial applications.

Key Features

• High Capture Efficiency: Captures CO₂ directly from air using solid amine materials; operation is flexible and not limited by location.
• Modular Design: Flexible module combinations allow adaptation to different CO₂ capture scales.
• Significant Economic Benefits: CO₂ supplied to greenhouses improves crop quality and yield, increasing agricultural income by 15%–20%.
• Flexible Operation: Single or multiple DAC module combinations can be used to suit various application scenarios.

Applications

• Greenhouse Agriculture: Provides direct air CO₂ supply to promote plant growth and increase agricultural productivity.
• Environmental Technology: Serves as an effective carbon capture and greenhouse gas reduction solution, supporting sustainable development goals.
