Sirona Technologies manufactures modular direct air capture units that chemically filter CO₂ from ambient air and permanently store it via mineralization in basalt formations. The factory‑built modules are designed for rapid deployment alongside renewable electricity, delivering verifiable carbon removal credits to industries and governments seeking hard‑to‑abate emissions solutions.

Problem
Atmospheric carbon dioxide concentrations continue to rise, making it difficult for many sectors to meet net‑zero targets using emissions reductions alone. Existing sequestration options such as afforestation require large land areas and can lack long‑term storage security.
Solution
Sirona Technologies builds modular Direct Air Capture (DAC) units that chemically filter CO₂ from ambient air. The captured CO₂ is released by steam injection and permanently stored through mineralization in basalt rock formations. Units are factory‑produced, allowing rapid field deployment and scaling in locations with abundant renewable electricity. By iterating designs quickly, Sirona reduces capital expenditure and improves capture efficiency, aiming to deliver large‑scale carbon removal capacity. Certified carbon removal credits are generated using sensor‑based measurement and third‑party verification, providing a verifiable offset product for customers.
Target Audience
Organizations and industries with hard‑to‑abate emissions that need verifiable carbon removal credits, as well as governments and renewable‑energy operators seeking to monetize excess clean power.
Features
- Factory‑built modular DAC modules that can be stacked into large arrays similar to solar farms
- Chemical filter media that selectively adsorb CO₂ and release it via low‑energy steam injection
- Permanent storage through mineralization in basalt rock, ensuring long‑term sequestration
- Sensor‑driven CO₂ capture measurement with third‑party verification for certified carbon credits
- Low‑capex design optimized for deployment in regions with cheap renewable electricity
- Rapid product iteration: three prototype generations built in one year, increasing capture capacity from 1 t yr⁻¹ to 20 t yr⁻¹ per unit
- Scalable deployment plan targeting 1 million t CO₂ yr⁻¹ by 2030, with a commercial plant slated for early 2026
