• Dotz Nano has secured a two-year, $696,000 supply agreement with Finnish direct air capture developer Soletair Power.
• The deal will supply carbon-capture sorbent for modular systems that integrate with existing building ventilation and thermal infrastructure.
• Soletair Power says each HVAC-integrated unit can capture up to 20 tonnes of CO2 annually, creating a potentially scalable route for building-based carbon removal.

US-traded Dotz Nano has secured a two-year carbon-capture supply agreement worth approximately $696,000 with Finnish direct air capture developer Soletair Power.

The agreement moves Dotz’s specialist sorbent technology into a commercial supply programme. It also gives the company a European customer as demand grows for carbon removal technologies that can integrate with existing infrastructure.

For Soletair Power, the contract secures a 24-month supply of a material central to its direct air capture systems. The Finnish company is developing modular technology that captures carbon dioxide from ambient air passing through buildings.

Bringing direct air capture into buildings

Soletair Power is taking a different approach to direct air capture by integrating its technology with existing ventilation and industrial thermal infrastructure.

Ambient air already moving through a building passes across the sorbent. Carbon dioxide is captured before being released in concentrated form using heat and vacuum. The captured CO2 can then be used or stored.

This model could reduce some infrastructure requirements associated with standalone direct air capture facilities. It also places commercial buildings within the emerging carbon removal ecosystem.

Soletair Power says each HVAC-integrated unit can capture up to 20 tonnes of CO2 annually. Additional modules can be installed where greater capacity is required.

The company has delivered seven direct air capture systems to date. Its projects span Finland, Germany, Denmark and Hungary.

Petri Laakso, chief executive of Soletair Power, said the agreement would support the company’s next stage of deployment.

“This partnership with Dotz validates our technology pathway and secures the sorbent supply essential for scaling our direct air capture operations. We’re pleased to work with an Australian innovator bringing world-class materials to Nordic carbon removal.”

Dotz moves towards commercial revenue

For Dotz, the contract represents a shift from technology development towards recurring commercial supply.

Reliable sorbent availability is critical for direct air capture developers seeking to move beyond pilot projects. Performance, cost and supply security can directly affect the economics of carbon removal at scale.

Nati Harpaz, chief executive of Dotz Nano, said the agreement establishes a pathway towards wider commercial adoption. “Moving Dotz from the laboratory to commercial customer engagement is a critical inflection point for our technology roadmap. Soletair Power’s validation of our carbon-capture sorbent demonstrates the real-world performance required for market adoption in direct air capture applications. This agreement marks the beginning of a significant commercialisation pathway for Dotz’s advanced materials in the climate solutions sector, and we anticipate further customer partnerships and scaling opportunities as demand for carbon removal solutions accelerates globally.”

The agreement gives Dotz greater exposure to Europe’s developing carbon removal market. It also provides Soletair Power with supply certainty as it expands Nordic operations.

Building decarbonisation strategy expands

The carbon-capture contract follows another commercial development for Dotz in the building-energy sector.

The company recently announced its first paying 12-month ChillerAI pilot at Limassol Shopping Centre. The programme was accompanied by an Eneriqs AI technology licence and the appointment of Bridgeford Group as commercialisation and delivery partner.

Together, the projects position Dotz across two areas of building decarbonisation. Its sorbent technology targets carbon removal, while ChillerAI focuses on reducing energy consumed by commercial cooling systems.

For building owners, investors and corporate sustainability teams, that combination reflects a broader shift in decarbonisation strategy. Energy efficiency remains a priority, but carbon removal technologies are increasingly being developed alongside conventional emissions reduction measures.

The commercial challenge will be scale. At up to 20 tonnes of CO2 per unit annually, individual installations remain relatively small compared with large industrial carbon removal projects. Modular deployment, however, could allow capacity to grow across portfolios of buildings.

For Dotz, the next test is whether this initial European agreement can translate into larger contracts and additional customers. For the wider market, the Soletair Power model offers another route for integrating carbon removal into infrastructure that companies already operate.
