Klimate Tek offers a range of carbon removal solutions built around its core direct air capture technology, combined with a portfolio approach that includes other high-quality methods . Their offerings can be broadly grouped into two main categories:

🏭 Engineered Solutions: Direct Air Capture

This is Klimate Tek’ foundational technology. They design, build, and operate machines that chemically capture CO₂ directly from the ambient air .

  • The Process: Giant fans draw air into collectors where CO₂ is captured on a filter. The filter is then heated—using renewable energy from sources like Iceland’s geothermal plants—to release the pure CO₂ .

  • Permanent Storage: For their core removal service, the captured CO₂ is handed to partners like Carbfix, who mix it with water and inject it deep underground. There, it reacts with basaltic rock and turns into stone within a few years, locking it away permanently .

  • CO₂ Reuse: In some cases, the captured CO₂ can be sold as a raw material for products like carbonated drinks or carbon-neutral fuels, though permanent removal is their primary climate solution .

🌳 Curated Portfolios: A Blended Approach

Recognizing that no single solution can address the climate challenge, Climeworks also offers Klimate Tek Solutions, a platform that curates a mix of high-quality carbon removal methods .

  • The Portfolio Approach: They create tailored portfolios for clients that combine Climeworks’ own engineered removal with other best-in-class solutions . This helps customers meet their sustainability goals by diversifying their investments across different technologies and nature-based approaches .

  • Types of Solutions Included:

    • Engineered: Primarily their own direct air capture with storage, but the portfolio model allows for inclusion of other innovative technologies like bioenergy with carbon capture and storage (BECCS) and enhanced rock weathering .

    • Nature-Based: These include projects like reforestationafforestationmangrove restoration, and biochar production, which stores carbon in soil
