Turning Buildings into Carbon Sinks.

Soletair Power develops modular direct air capture systems that enable companies, corporations and commercial building owners to capture CO2 directly from the air and be a part of the large-scale deployment of carbon dioxide removal measures.

How we remove CO2 from air

Why install CO2 capture systems in buildings?

Continuous increase in atmospheric carbon dioxide is causing the earth’s temperature to rise and leading to climate change. Reducing emissions is essential to slow global warming but it’s not enough. According to the National Academies of Sciences, Engineering and Medicine, the world must remove 10 gigatons of carbon dioxide per year from the atmosphere to avoid the worst impacts of climate change.

Buildings can be turned into carbon sinks by making them capture and permanently store CO2. Our building-HVAC-integrated CO2 capture system, alongside capturing CO2 from the atmosphere, improves the efficiency of the HVAC system and reduces CO2 in the office air benefiting the building residents with enhanced productivity and well-being.

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

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.

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.

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.

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 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 air, produce synthetic hydrocarbons, offset building emissions, and provide healthy air for people.
