Sirona DAC Initiatives for 2025: Key Projects, Strategies and Partnerships

Sirona Technologies: Scaling a Modular Revolution in Direct Air Capture

From Nascent Startup to Commercial Player: Sirona’s DAC Evolution

Between 2021 and 2024, Sirona Technologies emerged as a Brussels-based startup with a distinct vision for Direct Air Capture (DAC). Founded in 2023, the company’s initial phase was characterized by foundational development, focusing on a “plug-and-play” modular system using a chemical filter. The primary application was theoretical, aimed at designing scalable machines and securing foundational partnerships, such as the 2024 agreement with Cella and Great Carbon Valley to establish a future DAC hub in Kenya. This period represented a strategic groundwork phase, positioning the company to enter the market.

The period from January 2025 to today marks a significant inflection point, signaling a pivot from planning to execution. The key development was the launch of Sirona’s first commercial DAC machine—a unit housed in a 40ft container capable of capturing 300 tons of CO2 annually. This move from concept to a tangible, operational asset built in just six months underscores a rapid development cycle. The application of Sirona’s technology has diversified from hardware development to a service-based model. The company is now actively selling DAC credits on the market for delivery across 2025, 2026, and 2027 through partners like Agendi and Hexa. This transition from a technology developer to a carbon removal service provider validates its commercial viability. The primary opportunity is to prove the cost-effectiveness of this distributed model, while the threat remains the challenge of scaling to compete with larger, centralized DAC facilities.

Sirona Technologies’ growth is underpinned by a strategy of targeted, ecosystem-building partnerships. Early collaborations were designed to establish a framework for future deployment, which has since transitioned into active, operational projects that validate the company’s entire value chain, from capture to storage and monetization.

From European Roots to an African Foothold: Sirona’s Geographic Pivot

Between 2021 and 2024, Sirona’s geographic footprint was centered in Europe, with its founding and headquarters in Brussels, Belgium. This served as the hub for its initial research, development, and corporate strategy. The first signal of a global ambition came in 2024 with the announcement of a partnership to establish a DAC hub in Kenya, marking a strategic decision to deploy its technology in a region with high potential for renewable energy.

Since 2025, that strategic plan has materialized into a tangible operational focus on Africa. The launch of Project Jacaranda with Cella firmly establishes Kenya as Sirona’s primary deployment site. This shift is significant, indicating that the company is pursuing a strategy of co-locating its DAC technology with ideal environmental conditions—abundant solar energy for power and favorable geology for permanent mineralization storage. This makes Kenya a leading region for Sirona’s activities and suggests a broader trend where DAC deployment becomes mainstream in locations with synergistic natural resources, not just in traditional industrial centers. This presents an opportunity to build local cleantech value chains but also introduces potential risks associated with operating in emerging markets.

From Concept to Container: Tracking Sirona’s DAC Technology Maturity

In the 2021–2024 timeframe, Sirona’s DAC technology was in the pre-commercial development and demonstration phase. The focus was on refining the core concept of a modular, “plug-and-play” system powered by a chemical sorbent. The major milestone of this period was securing the €6 million seed round in June 2024, which was critical for transitioning the technology from a blueprint to a physical asset. The technology was validated at a conceptual level, attracting investor confidence based on its potential for scalability and cost-effective deployment.

The period from 2025 to the present has been defined by a rapid advancement to the pilot and early commercialization stages. The key validation point was the successful construction and launch of its first commercial DAC machine in a 40ft container, proving the company can execute its vision. This unit, with a stated capture capacity of 300 tons per year and built with off-the-shelf components, represents a tangible product. Furthermore, the integration of this technology into Project Jacaranda demonstrates system-level maturity, combining capture with solar power and mineralization. The most definitive signal of commercial readiness is the sale of multi-year DAC credits, which transforms the captured CO2 into a marketable commodity and validates the entire business model.

What to Watch: Scalability, Cost Curves, and Market Penetration

The data from 2025 signals that Sirona Technologies has successfully navigated the perilous journey from concept to an operational, revenue-generating company. The year ahead will be critical for proving its model at a larger scale. The market should no longer focus on whether Sirona *can* build its technology, but on how efficiently and quickly it can be replicated.

Market actors should pay close attention to three key signals. First is scalability: watch for announcements regarding the deployment of additional modular units and the total aggregate capture capacity. The success of the “plug-and-play” model hinges on rapid, cookie-cutter replication. Second is cost-effectiveness: any release of data on the operational cost per ton of CO2 removed from Project Jacaranda will be a major catalyst. This will determine its competitiveness and ability to attract larger offtake agreements. Finally, market adoption: the key signal is the expansion of its customer base beyond the initial partnership with Hexa. Securing more multi-year credit purchase agreements will validate the market’s confidence in its distributed, modular approach. Sirona’s model of rapid, distributed deployment is gaining significant traction, and its performance in the coming year will be a key indicator of the future of decentralized DAC.

Frequently Asked Questions

What is Sirona Technologies’ core business?
Sirona Technologies is a Direct Air Capture (DAC) company that has evolved from developing technology to becoming a carbon removal service provider. It builds modular, containerized DAC machines and sells the resulting carbon removal credits on the market through partners like Agendi and Hexa for delivery in 2025, 2026, and 2027.

What makes Sirona’s DAC technology different from others?
Sirona’s technology is based on a modular, “plug-and-play” system. Its first commercial unit is housed in a 40ft container, capable of capturing 300 tons of CO2 annually. This approach, which uses off-the-shelf components for a rapid six-month build cycle, focuses on a distributed model rather than building large, centralized facilities.

Why is Sirona operating in Kenya?
Sirona established its primary operational foothold in Kenya to co-locate its technology with ideal environmental conditions. The region offers abundant solar energy to power its DAC units and favorable geology for permanent CO2 storage through mineralization, a solution provided by its partner, Cella Mineral Storage.

What is Project Jacaranda?
Project Jacaranda is Sirona’s first operational pilot project in Kenya, launched in partnership with Cella Mineral Storage in February 2025. The project integrates Sirona’s solar-powered DAC machine with Cella’s permanent carbon mineralization storage, demonstrating a complete and operational capture-to-storage value chain.

How did Sirona finance the development of its first commercial machine?
Sirona secured €6 million ($6.4 million) in seed funding in June 2024 from investors including LocalGlobe, Xange, Look Up Ventures, and Satgana. This capital was specifically raised to scale its technology and directly supported the deployment of its first plant in Africa.
