Dotz Nano has signed a two-year, $696,000 supply agreement with Finnish direct air capture developer Soletair Power. The deal covers carbon-capture sorbent for modular systems that integrate with building HVAC and thermal infrastructure, moving Dotz from lab work into commercial revenue. Each unit can capture up to 20 tonnes of CO2 per year, and Soletair has delivered seven systems so far across Finland, Germany, Denmark, and Hungary. The contract gives Soletair a stable sorbent supply as it expands Nordic operations, while Dotz gains a European customer and a path toward larger contracts. The article also notes Dotz recently launched a ChillerAI pilot for commercial cooling efficiency, positioning the company across both carbon removal and building energy reduction. The key challenge is scale, since 20 tonnes per unit is small compared to industrial capture, but modular deployment across building portfolios could add up over time.
