Carbon capture technology company ION Engineering has initiated testing of its proprietary carbon dioxide (CO2) liquid absorbent system at Technology Centre Mongstad (TCM) in Norway.

This latest test campaign at TCM, which is the world’s largest and most advanced carbon capture test facility, aims to further scale-up and validate ION’s CO2 capture technology and reinforce its second generation liquid adsorption system for deployment on an industrial scale.

The Colorado-based company’s technology directs flue gas rich with CO2 into an absorption tower, where its solvent contacts the flue gas and absorbs the CO2. The flue gas, which is then cleansed of CO2, is returned to the stack and safely released into the atmosphere before the CO2-loaded ION solvent is directed to the regeneration section of the process and heated; at which point the CO2 is stripped from the solvent. The captured CO2 is then sent to be compressed and transported for either utilisation or sequestration purposes.

Due to the efficiency of ION’s novel solvent, required facility sizes are typically much smaller compared to units capturing similar levels of CO2 as well as enabling a reduction energy consumption.

This latest development represents next stage progressions of ION’s liquid absorbent system and is a continuation of the company’s multi-year Cooperative Funding Agreement with the US Department of Energy’s National Energy Technology Laboratory (NETL), under which ION will receive over $16m in funding in total.

ION’s CEO Alfred “Buz” Brown emphasised, ”TCM is an ideal environment that allows us to validate our process at a large industrial test facility. The opportunity to test at TCM represents the final step in our ability to deploy our technology at commercial scale.”

In 2015, ION successfully completed testing of its technology at the National Carbon Capture Center (NCCC) in Wilsonville, Alabama during its pilot scheme.
