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 remove CO2?

Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth’s temperature to rise. 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 also remove around an additional 10 gigatons of carbon dioxide from the atmosphere each year by mid-century to avoid the worst impacts of climate change.

Buildings can be turned into carbon sinks by making them pull CO2 out from the air and then by storing that CO2 permanently. Our building-HVAC-integrated CO2 capture system, alongside capturing tons of CO2 from the atmosphere, benefits the building residents with improved productivity and well-being.

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

For a standard ventilation unit handling 3.3 m^3 sec^-1, our Building HVAC Integrated CO2 capture system, the VIDAC 1.0, 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 is a technology that uses chemical materials to capture carbon dioxide from the atmosphere. When air moves over these materials, they selectively filter out CO2, allowing the other components of air to pass through.

DAC is needed alongside plantations because planting a trillion extra trees will remove only a quarter of the CO2 currently in the air. Also, DAC has a limited land and water footprint and can be installed at places close to suitable storage, eliminating the need for long-distance CO2 transport.

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

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

Our method can remove CO2 from air, produce synthetic hydrocarbons, offset building emissions, and provide healthy air for people.
