Aker Carbon Capture is a Norwegian-based Carbon Capture company. Their “Just Catch” series is applicable in industries with inlet CO2 concentration between 3% and 25%.
They claim competitive advantage based on the following:

The CO2-rich flue gasses are captured and pre-treated in the direct contact cooler. The purpose is to cool the flue gas and to remove any SOX and NOX pollutants. From the direct contact cooler the flue gas is transferred to the Absorber column (1.). The CO2 absorber consists of an absorption section in the lower part and a water wash section with an emission control system in the upper part. The flue gas contacts with the lean amine solvent in a counter-current flow regime, absorbing CO2 from the flue gas.
In the upper part of the column, the emission control system including the patented Anti-Mist design cools and cleans the theCO2-lean flue gas of traces of amines and potential amine degradation products, thereby preventing their release to the atmosphere in the form of aerosols.
Just Catch: Aker Carbon Capture uses a proprietary Amine-based solvent. They claim several advantages:
The CO2-laden solvent travels from the absorber tower (1.) to the desorber unit (2.). There it undergoes heat treatment and releases the pure CO2. The regenerated amine is returned to the absorber, while CO2 exits the top of the desorber.
Just Catch: Also in this step Aker Carbon Capture claim several advantages due to their proprietary technology:
Once the CO2 has been separated, it is processed to achieve the desired purity and compressed for transport.
Just Catch: Aker Carbon Capture utilizes heat recovery from the compression for more energy-efficient capture. It is a patented technology, which reduces the requirement for thermal energy down to approximately 2 GJ/tCO2
Aker Carbon Capture has developed multiple ways to improve their energy efficiency. The amine carbon capture process requires mainly thermal heat for its operation. To minimize the requirement for thermal heating, Aker Carbon Capture have developed their “Energy Saver” technology with Man Energy Solutions to introduce more electricity in the process and thus reduce the overall energy requirement by around 10%.
Further, if waste energy from CO2 compression is further harvested, the overall energy demand decreases by 20%. This is achieved by introducing a bit more electricity, resulting in a final split between electrical and thermal energy 35% to 65% respectively.
In a capture scenario where steam is not available, Aker Carbon Capture can also provide fully electric solution via heat pumps.
The Aker Carbon Capture Mongstad project (TCM) is a full-scale carbon capture and storage (CCS) facility located at the Mongstad industrial complex in Norway.
The Aker Carbon Capture Twence CCU project is a collaboration between Aker Carbon Capture and Twence, a Dutch waste management company. It involves capturing CO2 emissions from Twence’s waste-to-energy plant in Hengelo, Netherlands, and converting it into a usable product. This captured CO2 will be utilized in the greenhouse horticulture sector as a plant growth enhancer.
The Aker Carbon Capture Brevik CCS Project is a large-scale carbon capture and storage (CCS) project located at the Norcem cement plant in Brevik, Norway. It aims to capture and permanently store CO2 emissions generated by the cement production process.
The Aker Carbon Capture Ørsted CCS Project is a large-scale carbon capture and storage (CCS) project involving five Just Catch™ modular capture units at two Ørsted bioenergy power stations in Denmark.
