Project Description

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.

Project Benefits

Advancing the state of technological readiness of Carbon Engineering’s dilute-source CO2 capture technology will allow for a better understanding of its performance and costs and the external market environments in which it might be commercialized. If scaled to 1 million tons of CO2 per year and having low technical risk and powerful economic scale, this dilute CO2 capture technology can aggregate or negate emissions streams from a variety of small-scale sources that might be too technically challenging or too costly to mitigate at each individual source, in addition to atmospheric CO2 capture.
