The story of Soletair Power

Ever felt tired and lost train of thought in a meeting room?

Maybe the CO2 concentration in your room is getting high. We spend 90% of our time indoors and under high CO2 concentration indoors, our complex decision-making functions reduce significantly. In 2016, Harvard University found that human cognitive function starts to decline by 20% for each 400 ppm increase of CO2. It’s been proven that employees had 61% higher cognitive scores in CO2 lean environments. Soletair Power captures carbon dioxide from building ventilation utilizing DAC technology and increases peoples’ productivity.

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.

Protecting existing forests and planting new trees are surely good things to do. But planting a trillion extra trees will remove only a quarter of the CO2 currently in the air. The problem is that our society is releasing CO2, that are warming the Earth’s climate to levels we have never experienced before. Trees will definitely help us slow climate change, but they won’t reverse it on their own.

Soletair Power’s technology is the first in the world to integrate DAC with HVAC in buildings. It captures CO2 from ventilation units inside buildings to improve air quality. In addition to reducing carbon emissions, the integration of DAC indoors can improve humans’ cognitive function.

Our method can produce synthetic hydrocarbons profitably. At the same time, more productive air is brought to the offices.
