Technical Specifications of the Building HVAC / Ventilation Integrated Direct Air Capture of CO₂ Unit from Soletair Power

Soletair Power offers three categories of products:

  1. Indoor CO₂ Capture Unit for boosting Productivity
  2. Building Ventilation Integrated CO₂ Capture Unit for Productivity, Low Emission, and Carbon Utilization
  3. Outdoor CO₂ Capture Unit for Carbon Capture and Utilization

We also provide Productive-Air-as-a-Service for offices. The service cost is the same as the coffee benefit: $1- $2/day/employee; companies do not require to buy the whole system.
For companies that produce valuable products out of CO₂, we supply 99.99% pure CO₂ captured directly from the air.

In 2021, we have demonstrated our Power-to-X system at the EXPO 2020 Dubai.

Soletair Power: Making buildings carbon sinks

Direct air capture of carbon dioxide is often associated with large filter machines piled one on top of another and moving large volumes of air. Large contact points are required due to the small concentration of carbon dioxide in the air and because of the large daily production targets of these plants. As air is pushed in the filter, carbon dioxide and moisture are trapped or adsorbed. When the filter is saturated with these compounds the machine is closed and regenerated via vacuum and heating to collect the CO2 and water. Moisture is condensed leaving pure CO2 for compression.

Soletair Power delivers solutions for capturing CO2 in air supplied to building ventilation. The same adsorption and regeneration principle is used in our system to capture carbon dioxide but the dimension is compact. The captured CO2 is integrated inside an electrolyzer and synthesis unit, where it gets converted to fuels or other hydrocarbons.

Our Approach

Many factors govern the design of ventilation systems, Soletair Power’s ventilation-integrated CO2 capture system is designed to work within these established design requirements. The system is aimed to meet the ventilation speed typically in m3 sec-1 and the customers preferred indoor CO2 level measured as parts per million or ppm.

For a standard ventilation unit handling 3.3 m3 sec-1, our CO2 capture system will have a dimension of 3 m (L), 2 m (W), and 2 m (H) and can produce 47 kilograms of carbon dioxide per day. Due to the space limitation in the HVAC room, the system’s piping, and dimension can also be modified to fit the customer’s specifications.

Visual outlook of our system installed in an HVAC room

Below is an example of the visual outlook of our system installed in an HVAC room.  The system can be installed as a turn-key solution or can be assembled on site. The latter is especially suited to building retrofit installation where the access path to an HVAC system can be limited.

The system has a modular design principle therefore it is easy to install multiple units if required. The conversion of the CO2 to fuels or other hydrocarbons is done in a separate room in the building. Carbon dioxide from the CO2 capture system is piped to this room.

About Soletair Power:

Soletair Power is a Finnish startup founded in 2016 that manufactures solutions for carbon capture directly from the ambient air. Their technology can capture CO2 utilizing buildings’ HVAC systems and the captured carbon dioxide can be stored as long-lived products such as hydrocarbons or synthetic fuel. The technology being used is Direct Air Capture.
