Turning buildings into carbon sinks

We leverage buildings’ ventilation systems to capture atmospheric CO₂ by retrofitting HVAC with direct air capture technology. Buildings become net-negative carbon sinks when concrete locks the captured CO₂ inside.

Building-integrated CO₂ capture: Closing the emissions gap.

Shifting to renewables is allowing the world to reduce emissions across many parts of the economy, however, real estate emissions remain difficult to avoid.
Buildings, responsible for 38% of global emissions, can be turned into carbon sinks by making them capture and permanently store CO₂.
Our patented Building-HVAC-Integrated CO₂ Capture Technology is different from most carbon removal solutions that need high temperatures or specific geography.
Our weatherproof system has the ability to run entirely on renewable electricity and operate inside a building. CO₂ is captured utilizing buildings’ existing HVAC system and the residents enjoy CO₂-lean air. Captured CO₂ returns to the building in the form of concrete blocks and creates negative emissions.

What is a carbon sink?

A carbon sink is a reservoir that stores carbon dioxide permanently after capturing it from the atmosphere.

How much CO2 can Soletair Power capture?

For a standard ventilation unit handling 3.3 m³/s, our Building-HVAC-Integrated CO₂ Capture Unit can capture 47 kilograms of carbon dioxide per day per module. On average, there are six modules per building. So it’s around 300 kg/day from an average commercial building.

What is direct air capture (DAC)?

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.

Why are DAC and carbon sinks needed?

One of the biggest benefits of direct air capture is siting flexibility. DAC does not require arable land, which can minimize impacts on food production or other land uses. DAC is needed alongside plantations because planting a trillion extra trees will remove only a quarter of the CO₂ currently in the air (Ref: BBC). DAC also has a limited land and water footprint and can be installed in places close to suitable CO₂ storages, thus eliminating the need for CO₂ transport.

What is the effect of CO2 on people in buildings?

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.

What makes Soletair Power unique?

Soletair Power’s technology is the first in the world to integrate atmospheric carbon removal utilizing ventilation systems in buildings. In addition to offsetting building’s CO₂ emissions, HVAC-DAC integration can reduce HVAC’s operational costs, and improve people’s well-being. This also brings in the potential to create a localized supply of alternative energy sources.

Our method can capture CO₂ from the air, offset emissions, make buildings energy efficient & provide healthy air. Captured CO₂ can be stored permanently in concrete, or be used to produce synthetic hydrocarbons using Power-to-X.

What our customers are saying.

The visitors at Wärtsilä’s Sustainable Technology Hub (STH) in Vaasa may check out the Auditorium Archipelago on the ground floor of STH and discover the next best thing. Thanks to the HVAC-connected CO₂ capture unit – courtesy of the Finnish startup Soletair Power – carbon dioxide is radically reduced from the air before it enters the auditorium.
