Technical specifications

SOLETAIR process aims for 100% renewable solution, which combines CO2 from air and electricity from sun into sustainable consumer products. Our 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. Our ambition is to integrate these units successfully and demonstrate that 100% renewable future is possible

Phase 1: Renewable energy

Phase 2: Hydrogen production

Phase 3: Direct Air Capture (DAC)

Phase 4: Mobile Synthesis Unit (MOBSU)

Phase 5: Refinining of renewable products

Phase 6: Renewable consumer products

SOLETAIR project aims to demonstrate a process that would bind CO2 emissions and surplus electricity into everyday renewable consumer products. Depending on the chosen synthesis unit (methanation or Fischer-Tropsch) and following upgrading process, the ultimate product can be something as simple as synthetic natural gas or complicated petrochemical compounds like polyurethane.

In the case of gaseous products, synthetic natural gas is easy to utilize as such. The product quality is very high and therefore the gas can be directly injected into natural gas grid. Natural gas is widely used by consumers in Europe for heating, cooking and fueling vehicles. In Finland, natural gas is predominantly used in the combined heat and power production1. The renewable synthetic natural gas from SOLETAIR process can be used in cars and domestic appliances also in Finland, to increase the share of renewable in the natural gas consumption.

When the SOLETAIR process is operated in the Fischer-Tropsch mode, the main part of the renewable consumer product is liquid fuels: gasoline, kerosene and diesel. These fuels are high quality, they can be mixed with fossil-based fuels and used in the vehicles. The combustion of the fuel in an engine releases CO2 emissions, which can be again utilized by the SOLETAIR process creating a closed CO2 loop.

If the renewable hydrocarbons are refined to olefins and aromatics instead of fuels, wide range of possible renewable consumer products exists. The simplest and cheapest olefin-based product is polyethylene which is the most common plastic. However, SOLETAIR process is aiming for the higher-value products, which are based on three aromatic compounds: benzene, toluene and xylene. These are building blocks for complicated and valuable polymers, such as polyurethane, which is used in the soft and elastic foam of sneakers. Renewable plastic products like polyurethane sequestrate CO2 unlike fuels, which release CO2 back to atmosphere. Therefore, every renewable consumer product, every pair of sneakers with SOLETAIR components removes CO2 permanently from the atmosphere with purely renewable process.
