Capturing CO₂GrowingThe Future.

fortyfour is a climate-tech startup pioneering Direct Air Capture for Utilization. We capture CO₂ directly from the air, turning the atmosphere into your supplier. On-demand. On-site. On economics that work.

Solutions

Decentralized CO₂ for sustainable Greenhouses

Supply Independence

Make your own CO2 directly from the air. Boost plant growth by up to 30% with a local supply that eliminates tank deliveries and fossil fuel combustion. Our systems deliver CO₂ when your crops need it most—during peak photosynthesis, not just when the heating runs.

Superior Integration

Our systems integrate seamlessly with your existing equipment and turn electricity and optionally waste heat into CO2. Smart controls shift operation to low-price electricity hours, cutting energy costs while ensuring plants always have enough CO₂ to thrive.

Sustainable & Future-Proof

Meet emerging CO2 regulations and carbon neutrality mandates while positioning your greenhouse as a sustainability leader. Turn compliance into competitive advantage – lock in predictable and low CO2 costs as fossil-based options get increasingly expensive through rising taxes.

The Future of CO₂ is distributed

Greenhouse filled with lush plants representing CO₂ distribution.

The Challenge Industries worldwide depend on CO₂ as a critical resource, yet traditional supply chains are breaking down under the urgency of climate action. Rising carbon taxes, transportation vulnerabilities, and tightening regulations are making fossil-based CO₂ increasingly unviable. Today's industrial economy consumes over 200 million tons of CO₂ annually, from greenhouse enrichment and food processing to fertilizer production. By 2050, demand will exceed 6 gigatons as new applications emerge in e-fuels, carbon-negative materials, and synthetic chemistry. The way we source this industrial feedstock needs to fundamentally change.

The Opportunity Direct Air Capture transforms CO₂ from a transported commodity into a sustainable and on-site resource. By producing CO₂ where and when it's needed, we eliminate the inefficiencies of centralized production and distribution, cut transport emissions, and enable a defossilized industrial future.

The Solution Our liquid sorbent technology makes distributed CO₂ production economically viable, not through subsidies or distant promises, but through engineering that competes with fossil alternatives on price. Proprietary chemistry optimized for industrial use delivers the purity, volume, and reliability your operations demand, without the carbon footprint or supply chain complexity. By focusing on utilization rather than geological storage, we achieve significant cost advantages over traditional Direct Air Capture approaches.

How It Works

Engineering Simplicity from Complexity

Cuts reliance on fossil-fuel-based enrichment systems, lowering operational expenses for growers.

/01

Air Movement

The air around us contains a tiny fraction of CO₂. Our system draws high volumes of air through a contactor. The airflow is slow and even, which makes the process efficient without wasting energy.

/02

CO₂ Capture

Inside the contactor, our proprietary liquid sorbent flows cross-current to the incoming air. The sorbent has special molecules that selectively bind with CO₂, chemically absorbing it from the airstream and forming a stable solution.

/03

Controlled Release

The CO₂-loaded sorbent is moved to another stage where temperature and pressure are precisely adjusted. These changes unlock the CO₂ as a concentrated and pure stream that is ready for utilization.

/04

Solvent Regeneration

The sorbent is then restored to its original capture-ready state through controlled cooling and conditioning. This closed loop means the same liquid can be reused many times, making the process efficient and sustainable.

/05

CO₂ Supply

The CO₂ is collected and delivered at application-specific purity levels. We can adjust and tailor the stream from moderate purity for agriculture to high purity applications such as food & beverage and industrial use.
