Project Jacaranda by Sirona Technologies

Sirona Technologies is a Brussels headquartered company developing innovative DAC machines that have the potential for rapid scaling. Their pilot facility in Kenya will mark the fastest DAC pilot deployment in the world.

Kenya’s abundant geothermal and solar resources, combined with the storage potential, create a unique opportunity for DAC.

The project will not only accelerate large-scale carbon removal, but also stimulate local industrial demand for renewable energy.

Sirona was started to address to urgent truths: the world needs carbon removal at scale, and DAC can’t afford to move slowly. They designed a modular operational model to scale quickly, but needed a site that matched. Kenya offers exactly what DAC needs to scale: abundant renewables, favourable regulation, and critically, CO₂ storage infrastructure in place with our partner Cella. That’s where Project Jacaranda began.

Deploying this technology at unprecedented speed in a region rich in renewable energy and geological potential demonstrates that DAC can scale globally. But more than that, Project Jacaranda shows what’s possible when climate innovation is rooted in local partnership, purpose, and urgency.

• The carbon is stored in geological formations where it is mineralised and stored for at least 1000 years.
• Sirona has partnered with Cella Mineral Storage who's unique approach to mineralisation aims to use 20 times less water than other carbon mineralization providers.
• Sirona has overcome traditional DAC challenges such as long construction times and high costs by developing a modular and easily-scalable system powered directly by on-site renewable energy.
• Sirona’s operations are powered entirely by renewable energy, both for electricity and thermal needs. Electricity is sourced from their own solar farms and Kenya’s national grid, which is 93% renewable. Thermal energy is supplied through a combination of on-site geothermal heat and heat pumps with thermal storage.
• In a eco-sensitive location, the project has taken additional steps to limit the impact of their operations on nearby endangered species. A detailed site decommissioning plan is also in place to avoid groundwater pollution and ensure carbon remains stored for thousands of years.
• Sirona supports local infrastructure with water and healthcare access, prevents wildlife disturbance through buffer zones, and ensures community alignment via extensive stakeholder engagement.
• Sirona aims to use the highly-detailed Isometric as its certification partner and digital MRV system to track and verify its operations from removal to sequestration. Storage partner Cella also has extensive post-project monitoring measures to ensure the carbon removed remains safely stored.

At the heart of Sirona's approach is speed: they design modular machines, mass-produced in Belgium, to scale DAC fast and improve with every deployment. Each machine is a new iteration aiming to be more energy-efficient, more cost-effective. They brought their first pilot online in under 19 months from founding, and are on track to reach megaton-scale removal by 2030.

In Kenya, Project Jacaranda brings more than carbon removal: it creates jobs, strengthens local energy infrastructure, and invests in community-led initiatives.

Sirona's operation model is designed for speed and cost reduction. They mass-produce modular machines from off-the-shelf components, improving performance with every iteration. Plug-and-play deployment allows them to scale rapidly while driving down costs, without the complexity of large infrastructure.

To ensure that all carbon credits are high-quality, permanent, and transparently verified, Sirona Technologies follows the Isometric DAC protocol v1.1, with certification currently in progress.
