Direct Air Capture system using microalgae technology

Direct Air Capture (DAC) Technology Using Living Systems

Direct Air Capture (DAC) is a carbon dioxide removal technology that extracts CO₂ directly from ambient air. Carbelim’s microalgae-powered DAC system combines biological efficiency with precision engineering to enable scalable, permanent carbon sequestration.

Direct Air Capture

The Biological Advantage in Carbon Capture

Unlike conventional DAC systems that rely on energy-intensive sorbents and thermal regeneration cycles exceeding 900°C, Carbelim harnesses microalgae nature’s carbon capture champions to remove atmospheric CO₂ with unprecedented efficiency and minimal energy consumption.

Our nature-enhanced DAC pathway creates a closed-loop system where captured carbon transforms into valuable biomass, then engineered biochar, delivering permanent carbon storage that satisfies the most rigorous MRV (Monitoring, Reporting & Verification) standards for climate commitments worldwide.

Why Microalgae Outperforms Traditional Direct Air Capture

Biomimicking Technology

400x Faster CO₂ Capture


Microalgae assimilate atmospheric carbon 400 times more efficiently than trees, making them amongst the world's most powerful biological carbon removal mechanisms available for industrial deployment.

Negligible Energy Cost

Low-Energy Operation


Our continuous DAC operation consumes significantly less energy than most other existing DAC companies worldwide, due to innovative technology and process efficiencies that minimize power use without compromising performance.

Modular Engineering

Globally Scalable


Deploy as urban facade systems, rooftop farms, modular pods for remote locations, or photobioreactor fields across desert, coastal, and industrial environments worldwide.

Biomimicking Technology

Complete Carbon Removal Lifecycle

Carbelim’s DAC system operates as a fully integrated carbon capture, utilisation, and storage (CCUS) pipeline—from atmospheric intake through permanent sequestration.

Atmospheric CO₂ Intake
Ambient air flows continuously through transparent photobioreactors containing optimised microalgae strains engineered for rapid CO₂ fixation and stable year-round growth.
Enhanced Photosynthesis
Microalgae convert CO₂ into oxygen and dense biomass using biomimetic light-harvesting mechanisms, optimised lighting, pH balancing, and turbulent-flow circulation.
Biomass Harvesting
Captured carbon is harvested as concentrated algal slurry using gravity separation, microfiltration, and low-energy drying technologies.
Biochar Engineering
Biomass blends with agro-forestry residues in controlled pyrolysis, producing ultra-stable biochar locking carbon for centuries.
MRV & CDR Credits
Full MRV enables verifiable carbon removal credits with QR-coded batches and geotagged audit trails.

Deployment Versatility Across Environments

Urban Infrastructure

Transform building facades, rooftops of commercial complexes, smart-city infrastructure, and roadway corridors into distributed carbon sinks integrating climate action directly into the urban fabric where emissions concentrate.

Industrial Facilities

Co-locate DAC farms at cement plants, steel mills, glass manufacturers, chemical facilities, refineries, and logistics hubs enabling facility-level carbon dioxide removal at the source of hard-to-abate emissions.

Remote & High-Emission Zones

Deploy modular DAC pods in deserts, arid regions, landfills, waste sites, and renewable energy farms turning underutilised land into productive carbon removal infrastructure with minimal water requirements.

Agricultural Regions

Establish DAC farms co-located with agricultural operations where agro-residues can be integrated into biochar blending creating circular carbon economies that enhance soil health whilst removing atmospheric CO₂.

Performance Metrics That Matter

Direct Air Capture FAQs

Direct Air Capture technology can be applied across industries with high or hard-to-abate carbon emissions, including manufacturing, cement, steel, energy, commercial buildings, data centers, and urban infrastructure. DAC is especially suitable where emissions are diffuse or cannot be captured at the source, enabling organizations to address residual and legacy CO₂ emissions.

In industrial and commercial settings, Direct Air Capture systems continuously draw in ambient air and selectively remove carbon dioxide. Carbelim’s biological DAC approach uses microalgae to naturally absorb CO₂ through photosynthesis, converting it into biomass. This process operates at ambient conditions, reducing energy demand compared to conventional thermal or chemical DAC systems.

The cost of Direct Air Capture depends on scale, energy use, and system design. Biological DAC systems can offer improved cost efficiency by operating at low temperatures, reducing energy intensity, and enabling modular deployment. For large facilities with sustainability or net-zero targets, DAC can become economically viable when integrated with carbon utilization strategies and long-term decarbonization plans.

Traditional carbon capture systems typically capture CO₂ directly from industrial exhaust streams, while Direct Air Capture removes carbon dioxide directly from the atmosphere. DAC can address emissions that are already released or cannot be captured at source, making it complementary to CCS. Biological DAC further differs by using natural processes instead of energy-intensive chemical sorbents.

Biological Direct Air Capture can be suitable for industrial and large-scale facilities when implemented as a distributed or phased solution. Carbelim’s approach is intended to reduce operational complexity and energy demand compared to traditional DAC, making it adaptable for pilot projects and scalable deployments.
