Turning Buildings into Carbon Sinks.

Soletair Power is a carbon capture company from Finland. We develop building-integrated Direct Air Capture technology retrofittable within urban infrastructures. Our HVAC integrated CO2 capture technology enables buildings to remove CO2 from the air at ambient airflow rates. Captured CO2 can be stored or utilized in the concrete industry resulting in negative emissions.

Why Buildings?

Carbon minus⁻

Run on renewables, captures more CO2 than it emits.

Retrofittable

Easily retrofits with the existing HVAC system.

Air+

Supplies CO2-lean air leading to better indoor air quality.

Permanence

CO2 mineralization enables long-term storage.

Buildings Need to be Decarbonized

Buildings, responsible for about 40% of global greenhouse gas emissions, can be turned into carbon sinks by making them capture CO2.
Soletair Power’s patented Building-HVAC-Integrated CO2 Capture Technology is developed for buildings and does not require high temperatures or specific geography. Atmospheric CO2 is captured from the air by utilizing the existing HVAC system. Captured CO2 when mineralized into concrete, returns to another building in the form of concrete blocks, closes the cycle, and creates negative emissions.

Why Buildings?

Our building-ventilation-integrated carbon capture technology benefits from the stable temperatures, waste heat, and the already moving air within a building’s existing HVAC system, delivering a geographically independent, weatherproof, economically viable, and round-the-year CO2 capture solution.

Learn what we do

A carbon sink is a reservoir that stores carbon dioxide for an indefinite period after capturing it from the atmosphere.

Direct air capture (DAC) is a technology that uses chemical materials to capture carbon dioxide from the atmosphere. When air is moved over these materials, they selectively capture the CO2, allowing the other components of air to pass through.

According to IPCC, limiting global warming to 1.5°C by 2100 will require technologies for large-scale deployment of carbon dioxide removal measures. DAC is needed alongside nature-based CO2 capture, enabling renewable energy and transitioning away from fossil fuels. DAC has a limited land and water footprint and can be installed in urban environments and in places close to CO2 storages.

High concentration of CO2 in the air indoors has a direct influence on how people think (Ref: Harvard University). The standard indoor CO2 level is expected to stay between 450 and 600 ppm, which is slightly above the normal levels in outdoor air (414 ppm). From 1,000 ppm, room occupiers start to feel dissatisfied and with every 400 ppm increase in CO2 concentration, our cognitive function score drops by 20%. CO2 undercuts our ability to perform in thought works at full potential.

Soletair Power’s technology is the first in the world to integrate atmospheric carbon removal in buildings. Soletair Power’s modules produce no additional noise and can capture CO2 even at a low airflow rate, making it ideal for installing in buildings.

In addition to offsetting a building’s CO2 emissions, HVAC-DAC integration can reduce HVAC’s energy costs, and supply better air indoors.

For a standard ventilation unit handling 3.3 m3/s, each of our Building-HVAC-Integrated CO2 Capture Unit can capture 47 kilograms of carbon dioxide per day, or 20 tonnes per year. On average, there are about 20 modules per building.

Each average commercial building eqipped with Soletair Power’s technology can capture about 400 tonnes carbon dioxide (about the same emissions as 87 cars) per year from the ambient air. Now imagine that for hundreds of buildings!

Capture CO2 onsite and transform buildings into carbon capturing machines.

OUR SOLUTION

Capturing CO2 by integrating DAC with HVAC

Soletair Power provides a cost-effective alternative for distributed direct air capture. We help building owners reduce their net emissions by integrating a CO2 capture technology called “Direct Air Capture” with the building’s HVAC system. Captured CO2 can be converted to carbonates where it stays permanently stored and can no longer contribute to climate change.

The building’s HVAC system pulls in air.

The incoming air is pushed through our proprietary sorbents. Carbon dioxide is selectively adsorbed by them.

When the filter is saturated, the machine is closed and regenerated via vacuum & heating to collect the captured CO2.

The captured CO2 is stored in a separate container near or inside the building.

CO2 can be supplied for making concrete.
