Turning buildings into carbon sinks.
Our modular direct air capture systems help reduce buildings’ CO2 emissions, save energy costs, and help companies comply with legislations (for example, LL97, 45Q, or EPBD) by making buildings capture carbon dioxide from the air.
Building-Integrated CO2 Capture
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 uniquely developed for installation in buildings and does not need high temperatures or specific geography. CO2 is captured throughout the year by utilizing buildings’ existing HVAC systems and the residents enjoy CO2-lean air. Captured CO2 returns to the building in the form of concrete blocks and creates negative emissions.
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.
