Established in 2016, Finnish carbon capture technology provider company Soletair Power is focused on global negative emissions by integrating Direct Air Capture into commercial building HVAC systems, both indoors and outdoors. The captured CO2 is stored in containers and supplied to concrete manufacturers for permanent storage.

In 2021, Soletair Power demonstrated a compact Power-to-X methane production module at Expo 2020 Dubai and installed an outdoor DAC unit at the ZBT hydrogen and fuel cell center in Duisburg, Germany in 2022. In 2023, they installed their HVAC-integrated DAC system at seed funding company Wärtsilä’s Sustainable Technology Hub building in Vaasa, Finland.

Soletair Power HVAC-integrated CO2 Capture system can capture up to 20 tCO2/year/unit and reduce energy consumption and cost of ventilation.

If the world wants to avoid catastrophic climate change, switching to carbon neutrality is not enough. IPCC has warned that limiting global warming to 1.5C by 2100 will require technologies such as direct air capture for large-scale deployment of carbon dioxide removal measures.

We turn buildings into carbon sinks.

Soletair Power addresses the issue of CO₂ emissions originating from buildings, responsible for nearly 40% of global CO₂ emissions. Existing direct air capture solutions face challenges in cost and efficiency. Soletair Power’s breakthrough lies in achieving net-zero emissions by integrating direct air capture with building ventilation systems, providing an economically viable solution for capturing CO₂, thereby generating negative emissions, reducing energy consumption, and improving indoor environments.

Soletair Power’s patented onsite HVAC integrated CO₂ capture technology empowers commercial property owners to reduce their buildings’ overall emissions while achieving significant cost savings. The technology captures CO₂ from the air by retrofitting ventilation systems with CO₂-binding materials, later converting the captured CO₂ into concrete. The modular carbon capture systems operate with a plug-and-play approach, enabling property owners to rapidly and easily install the system.

One HVAC-integrated DAC unit (in buildings with ventilation of 3 m³/s) can capture up to 20 tons of CO₂ per year, equivalent to 3 hectares of Nordic forest aged 30 years. If building ventilation runtime is controlled by CO₂ levels, the system will also help lower the costs of HVAC energy use.

Rather than relying solely on CO₂ emission offset sales, Soletair Power benefits from stable building temperatures for efficient and weatherproof onsite CO₂ capture. The technology operates below 100°C temerature leveraging existing heat, providing a remarkable edge over competitors.

The easy deployment of our modular carbon capture technology can significantly impact the carbon market when scaled. This benefits building owners, making it a financially feasible solution that can contribute positively to the planet.

We’ve showcased our ambient air CO₂ capture and fuel production using Power-to-X technology at Expo 2020 Dubai. Successful pilot initiatives have been undertaken, including a containerized outdoor carbon dioxide capture unit at ZBT in Germany with a daily capture capacity of 21 kg CO₂. Another unit deployed at the Wärtsilä Sustainable Technology Hub in Vaasa, Finland, has a daily capture capacity of 50 kg.

In 2024, a client is deploying our HVAC integrated CO₂ Capture unit at a factory in Vantaa, Finland where the capture CO₂ will be converted into a valuable resource. The next building ventilation integrated unit is scheduled to be deployed in Aarhus, Denmark. Each of these solutions has the potential to capture close to ~20 tonnes of CO₂ per year per ventilation unit.

Every day, we try to innovate ways to enhance our technology, our way of work and our spectrum of imagination. Our values live through the entrepreneurial spirit of our diverse and inclusive network.
