Aerbon

The project purpose is to develop direct air capture (DAC) technology and intends to build facilities for DAC on an industrial scale. The technology is based on research from KTH Royal Institute of Technology. Direct air capture involves 4 main steps: 1. Air is pushed through a collector using a fan

2. CO2 is captured on the surface by a highly selective filter material that sits inside the collector 3. When the filter is full, the collector is closed, a vacuum is generated and 60-85 degrees C heat is applied 4. CO2 can then be separated and stored for further use in industry or for long-term storage

What is new with the method is the energy use in the process and specifically the pairing of low-grade waste heat sources with DAC making the process both energy efficient and economically sound. 80% of the total energy need in the process can come from low-grade waste heat.
