Occidental acquires DAC technology company Holocene

April 17, 2025
Occidental Petroleum subsidiary Oxy Low Carbon Ventures has acquired Holocene Climate Corp., its second acquisition of direct air capture technology.

Occidental Petroleum subsidiary Oxy Low Carbon Ventures has acquired Holocene Climate Corp., Knoxville, Tenn.

Holocene holds liquid, low-temperature direct air capture (DAC) technology that Occidental said in a note on Holocene’s website is additive to technology acquired through Carbon Engineering Ltd. (OGJ Online, Aug. 15, 2023).

Occidental acquired Carbon Engineering in 2023 for about $1.1 billion after the two companies had been working together on DAC deployment since 2019, Occidental said at the time. 

On its acquisition of Holocene, Occidental said it believes combining the Carbon Engineering technology with that of Holocene’s technology “will enable us to advance our R&D activities to improve the efficiency of our direct air capture process, reduce CO2 capture costs and accelerate DAC deployment.”

On its website, Holocene describes itself as a DAC technology developer and carbon removal service provider harnessing organic chemistry to remove CO2 directly from the atmosphere “in support of restoring the climate stability and prosperity of our namesake, the Holocene Epoch.” 

In May 2024, the company publicly demonstrated its first industrial DAC pilot, noting a capture rate of about 80% as the plant took in about 450 parts/million CO2 and less than 90 parts/million CO2 came out. As part of the public demonstration news, the company said the pilot brought its technology scale to about 10 tonnes/year of CO2 capacity. Also noteworthy, Holocene said, was the team’s proven ability to scale 100,000x in less than 12 months.
