Sirona Technologies

What Sirona Technologies does

Sirona Technologies is a Belgium-based climate technology company founded in 2023 that develops and deploys modular Direct Air Capture (DAC) systems to remove CO2 from ambient air and permanently store it via geological mineralization. The core technology uses solid sorbents that selectively capture CO2 and release it under heat and vacuum; the system is engineered to be sorbent-agnostic, enabling adoption of improved materials without hardware redesign. Units are factory-built in Belgium to standardize production, steepen the learning curve, and accelerate cost reduction. Sirona operates commercial and pilot DAC projects across multiple geographies chosen for high-renewable electricity and suitable storage geology: Project Jacaranda in Kenya (with Cella Mineral Storage, basalt mineralization), Project Moringa in Oman (solar-powered, targeting 1,800 tonnes/year by 2026), and Project Furu in Norway (hydro-powered grid).

The business sells verified, permanent carbon removal credits through three channels: direct enterprise sales with multi-year offtake agreements, marketplace partners Patch and Climate Vault Solutions that route institutional demand to vetted suppliers, and a self-serve website storefront priced at $0.80 per kilogram for individuals and small businesses. Named enterprise customers include Shopify (first customer, via its Sustainability Fund), IMC, Hexa, and Wild Assets, with cumulative disclosed funding of approximately $7.4 million ($1M pre-seed in November 2023 and €6M seed in June 2024, led by LocalGlobe and XAnge). The company began commercial operations in 2025, with the first carbon removal credits scheduled for delivery in 2026.

Core offering

Sirona Technologies sells certified, permanently stored carbon removal credits generated by its factory-built modular Direct Air Capture (DAC) machines. The DAC units use solid sorbents to capture CO2 from ambient air; the CO2 is then injected underground into basalt or peridotite rock where it mineralizes into stone for permanent storage. Credits are sold directly to enterprise customers via sales-led contracts and multi-year offtake agreements, and to individuals and small businesses via a self-serve online shop priced at $0.80 per kilogram of CO2 removed.

Product overview

Sirona Technologies is a climate tech startup offering modular Direct Air Capture (DAC) systems and permanent carbon removal credits. The core product is their factory-built modular DAC technology that captures CO2 from ambient air using solid sorbents, with the captured CO2 permanently stored through geological mineralization. The company operates multiple DAC projects globally including Project Moringa (Oman), Project Jacaranda (Kenya), and Project Furu (Norway). Carbon removal credits are available for purchase by enterprise customers and individuals through their platform, with certified high-quality verification and permanent storage guarantees.

Direct peers

• Climeworks: Swiss pioneer and global leader in commercial Direct Air Capture using solid sorbents with geological storage. Sirona's technology, customer base (corporate net-zero buyers), and project economics directly mirror Climeworks, making it the most relevant direct competitor.
• Heirloom Carbon Technologies: US-based DAC company using limestone-based DAC technology with mineralization. Targets the same corporate voluntary carbon removal buyers with permanent, third-party verified credits and competes head-to-head on price-per-tonne and project scale.
• CarbonCapture Inc. US DAC developer building modular solid-sorbent systems with mineralization storage. Directly comparable technology approach and target market of enterprise carbon removal offtakers.
• CarbonOrO: German DAC startup using solid sorbents for modular carbon capture with permanent storage. Closely comparable early-stage European peer with similar technology stack and enterprise credit sales model.

Emerging players

• Avnos: US DAC company using a hybrid CO2-and-water capture process. Competes in the same high-quality engineered removal credit market but with differentiated technology producing water as a co-product.
• Phlair: German DAC startup developing modular electrochemical carbon capture systems for permanent storage. Competes with Sirona in the European engineered CDR market targeting corporate offtake buyers.

Broad incumbents

• 1PointFive (Occidental): Subsidiary of Occidental Petroleum deploying gigaton-scale DAC infrastructure (STRATOS plant) with saline aquifer storage. A much larger, capitalized peer pursuing the same enterprise removal credit market with conventional amine capture rather than solid sorbents.
• Carbon Engineering (Oxy DAC): Pioneering liquid-solvent DAC company acquired by Occidental. Operates STRATOS and competes for the same large-scale corporate offtake market with an alternative capture chemistry and incumbency advantages.

Others

• Patch: Carbon removal marketplace that facilitates multi-year offtake agreements. Functions as a distribution channel and infrastructure partner for DAC suppliers including Sirona, and is therefore an adjacent ecosystem participant rather than a competitor.
• Cella Mineral Storage: Carbon mineralization company providing underground basalt/peridotite CO2 storage services. Sirona's Project Jacaranda and Kenya DAC Hub partners with Cella, making it an enabling infrastructure peer rather than a direct competitor.
