Direct Air Capture (DAC) removes CO2 directly from the air. There are two main approaches: mechanical systems using chemical processes and biological systems using microalgae.

In 2026, biological carbon sequestration is proving more efficient, scalable, and economically viable.

Mechanical Direct Air Capture

Requires 1.5–2.5 MWh per ton of CO2

Needs high-temperature heating (80–120°C)

High capital and operating costs

Large industrial footprint

Depends heavily on subsidies

Biological Carbon Sequestration (Microalgae)

Requires less than 0.3 MWh per ton

Operates at ambient temperatures

Integrates into buildings and urban spaces

Produces valuable biomass (protein, biofuels, omega-3 oils)

Lower capital and operating costs

Why Biological Systems Win

Lower energy demand reduces costs by up to 70%. Modular design allows faster deployment. Captured CO2 becomes revenue-generating products instead of storage liability. Lifecycle emissions are significantly lower.

Mechanical DAC may serve niche industrial needs. But for urban scalability, cost efficiency, and long-term sustainability, biological carbon sequestration offers a stronger path forward.

Cities were engineered for commerce and connectivity—not breathable air. As density increases, pollutants such as CO₂, NOx, PM2.5, and VOCs accumulate at street level, directly impacting public health, cognitive performance, and economic productivity.
