Carbon Engineering Ltd. (Carbon Engineering) will further the development of a dilute-source carbon dioxide (CO₂) capture technology to capture CO₂ from coal‐relevant streams, such as post‐carbon capture and storage (CCS) flue gas, and re-capture legacy atmospheric coal-based emissions. Carbon Engineering’s dilute-source CO₂ capture technology, under development since 2009, was designed to scrub CO₂ from atmospheric air when present at a concentration of 400 parts per million (0.04 percent). The project aims to advance the state of technological readiness of the system to capture CO₂ at atmospheric concentration, identify and pursue advancements to the technology while also addressing technical risks or under-performance, and evaluate the system’s applicability to other coal-relevant streams such as post-CCS exhaust. Carbon Engineering’s Direct Air Capture (DAC) system is a process-based technology that centers on a wet scrubbing air contactor and uses several chemical processing steps to produce purified CO₂ and re-make the capture solution. Carbon Engineering will use its dilute CO₂ capture research pilot in Squamish, British Columbia, Canada, as a key testing platform for the project. A commercial readiness and cost-estimation effort will be conducted by Carbon Engineering to further understand technology development steps and the advantages and barriers to technology deployment.
