Built for infrastructure scale.
Engineered for the constraints that define modern infrastructure – power, water, heat, and siting.
Carbon Removal Infrastructure
A modular carbon removal system built for infrastructure scale
Hybrid Direct Air Capture (HDAC™) requires no external heat input, integrating carbon removal and water production into the infrastructure being built at global scale, including data centers, geologic storage hubs, and next-generation e-fuels and SAF production.
Unlike legacy DAC systems, HDAC requires no heat inputs, produces clean water rather than consuming it, achieves up to 50% lower cost, and enables deployment where conventional approaches cannot operate. The system integrates directly with existing infrastructure and delivers strong unit economics at scale.
Avnos is backed by more than $100 million in funding from partners including Shell, Mitsubishi Corporation, NextEra Energy, ConocoPhillips, JetBlue Ventures, the U.S. Department of Energy, and the U.S. Department of Defense.

Hybrid Direct Air Capture
What makes
HDAC different
Water-positive
HDAC produces clean water rather than consuming it — generating up to 4 tons of clean water for every ton of CO₂ removed.
Lowest-cost carbon removal
HDAC’s moisture-swing process reduces total energy use and operating costs by up to 50% compared with legacy DAC systems.
Modular and scalable
Standardized units deploy quickly and integrate with existing infrastructure and industrial systems, enabling carbon removal to scale across diverse environments.

How HDAC works
Hybrid Direct Air Capture combines atmospheric water extraction with a moisture-swing adsorption cycle to remove CO₂ while producing clean water in a single energy-efficient process. This design reduces total energy requirements by up to 50% compared with traditional DAC.
At commercial scale, HDAC’s modular architecture enables carbon removal costs below $250 per ton, with longer-term potential below $100 per ton. Avnos is deploying HDAC with global technology and industrial infrastructure companies and federal agencies working to scale durable carbon removal.
