Introduction: From Laboratory to Buildings and Offshore, China’s DAC Commercialization Process Accelerates
While global carbon capture technology remains hindered by high energy consumption bottlenecks, Chinese enterprises are innovating to open up new scenarios:
- Buildings Transform into Carbon Sinks Green Carbon Technology achieves426ppm indoor CO₂ removal in 1 minute
- Offshore Oil Fields Sequester CO₂ to Drive Oil Production China National Offshore Oil Corporation’s Enping platformsupercritical injection technology reduces costs by 40%
- Green Electricity Collaborates for Negative Emissions Linhe Climate collaborates with State Grid to tacklewind and solar power-driven DAC aiming for 2025 to be the year of explosive growth for domestic direct air capture technology from demonstration to large-scale application.
1. Building Revolution: Green Carbon Technology Creates the World’s First Residential DAC System
1. Huayu Lake, Nanjing: Buildings as Carbon Sinks
- Technical Breakthrough
- Utilizesthree-layer composite adsorbent (MOF + ion resin + porous carbon), improving humidity adaptability by 50%
- Achievesreducing 426ppm CO₂ concentration to nearly zero in 1 minute, simultaneously addressing indoor stuffiness
- Innovative Carbon-Sequestering Concrete
- Captures CO₂ and mineralizes it into building materials,with a carbon sequestration rate of 29.7% (153kg CO₂/m³)
- Strength comparable to ordinary concrete, curing time reduced by 30%
The core highlight of this project is the first integration of DAC technology into urban buildings. Unlike traditional industrial point-source capture, DAC technology captures carbon dioxide directly from ambient air, making it one of the key technological pathways to achieve “negative emissions.” Test data shows that this DAC system can reduce the CO₂ concentration at the inlet from 426 PPM to nearly zero in 1 minute. This not only provides an innovative solution to alleviate the “stuffy” feeling caused by high indoor CO₂ concentrations and enhance living comfort but also opens up a new avenue for urban buildings to actively participate in carbon reduction. The concrete carbon sequestration technology developed by the project team can stably solidify the captured CO₂ in the concrete, with a carbon sequestration rate (relative to cement usage) of up to 29.7%, equivalent to each cubic meter of concrete “absorbing” about 153 kilograms of CO₂. More valuably, this carbon sequestration process not only achieves long-term safe storage of CO₂ but also creates economic value.
