Abstract: Capturing CO2 from ambient air will always be more expensive than capturing from concentrated sources assuming that both facilities operate the same scale and face the same costs of capital, labour, energy and CO2 disposal, yet "air capture" may nevertheless be an important tool for managing carbon. I will describe technology for capturing CO2 from air being developed by Carbon Engineering, a start-up company. I will describe the engineering of the low-cost gas-liquid contactor and will address costing, technical risk, and results from a pilot facility who have commissions to test these risks.
