Soletair is a company that captures carbon directly from the air as carbon dioxide, and also hydrogen that the company produces by renewable electricity from the sun or wind. With the help of catalytic synthesis, Soletair combines hydrogen and carbons into hydrocarbons suitable for fuel and plastic production. Soletair integrates these sustainable technologies to demonstrate that renewable products from the sun and air are available.
The Soletair process aims for a 100% renewable solution, which combines carbon dioxide from air and electricity from the sun into sustainable consumer products. Soletair's demonstration facility includes a solar field, and three mobile container units - electrolyzer for hydrogen production, direct air capture for CO2 production, and intensified synthesis reactors for hydrocarbon production.
There are six phases in the process used by Soletair. The first phase is renewable energy. In this phase, the company powers the system with 100% clean solar energy. Power electronics transfer the electricity into the process. The second phase is hydrogen production. In this, they produce hydrogen using the electrolyzer module. The electrolyzer splits water molecules into H2 and O2. The hydrogen is then supplied to the next module. The third phase is direct air capture. Carbon dioxide is being collected from the air using the direct air capture module. Carbon dioxide is separated from the air by the adsorption process. The next phase is the mobile synthesis unit. Here, CO2 and H2 are being transferred to the mobile synthesis unit. An intensified synthesis reactor combines them into CXHY. Multi-functional hydrocarbons are used for fuel, gas, and plastic production. The CXHY is then being transferred to intermediate chemicals, oil refinery, and gas through the refining process. They are then being used for the next phase which is consumer products. They are also used for gasoline and diesel, and synthetic natural gas.
