Carbon Engineering

Carbon Engineering's DAC system integrates two main cycles. The first cycle is the absorption of from the atmosphere in a device called an "air contactor" using an alkaline hydroxide solution, and US20150329369A1. The second cycle regenerates the capture liquid used in the air contactor, and delivers pure as an end product. These cycles operate in tandem continuously, producing a concentrated stream of gas as an output, and requiring only energy, water, and small material make up streams as inputs. Energy is used in such a way that no new emissions are incurred, and thus do not counteract what was captured from the air. The captured atmospheric can be stored underground, used for enhanced oil recovery, or turned into low-carbon synthetic fuels using the company's "air to fuel" technology. This approach offers a means to deliver clean fuels that are compatible with existing engines, and can help de-carbonize the transportation sector by displacing fuels made from crude oil. ==Pilot plant demonstration==

In 2015, Carbon Engineering started operations of its full end-to-end pilot plant, located in Squamish, British Columbia, Canada. When running, this facility captures roughly 1 ton of atmospheric per day. Both DAC and air to fuel technologies have been proven at the pilot plant and are now being scaled up into commercial markets. Individual DAC facilities can be built to capture up to 1 million tons of per year in the near future. At that scale, one Carbon Engineering air capture plant could negate the emissions from ~250,000 cars—either by sequestering the or by using the recycled carbon dioxide as a feedstock to produce synthetic fuel. == Commercialization ==

In May 2019, Carbon Engineering announced it was partnering with Oxy Low Carbon Ventures, LLC. (OLCV), a subsidiary of Occidental Petroleum, to design and engineer a large-scale DAC plant capable of capturing 500,000 tonnes of carbon dioxide from the air each year, which would be used in OLCV's enhanced oil recovery operations and subsequently stored underground permanently. Located in the Permian Basin, construction for the plant is expected to begin in 2022, with operations targeted for 2024. In September 2019, Carbon Engineering announced they were expanding the capacity of the design of the plant from 500,000 tonnes to an expected one million tonnes of captured per year. In August 2023, it was announced Occidental Petroleum had acquired all the outstanding equity of Carbon Engineering for $1.1 billion. == References ==
