Captura, a carbon removal company founded at Caltech, and AltaSea at the Port of Los Angeles announced their partnership that will further advance ocean-climate solutions.
According ot the company, the latest system is a 100x scale-up from the company’s first pilot that has been operating at Newport Beach, California since August 2022.
Captura will use AltaSea’s campus as the site for technology testing, research, and analysis to validate, scale and improve its Direct Ocean Capture (DOC) technology.
This is what AltaSea is all about – bringing together key players from across the blue economy to scale ground-breaking technologies, forge new partnerships, and convene important conversations on topics critical to the fight against climate change.
…said AltaSea President & CEO Terry Tamminen.
As informed, Captura’s DOC technology leverages the ocean’s natural capacity as a carbon sink to remove CO2 from the atmosphere. Powered by renewable energy, the process uses proprietary electrodialysis technology to capture CO2 directly from seawater and deliver it as a measurable stream that can be permanently sequestered or utilized. When the CO2-depleted seawater is returned to the ocean, it has the capacity to absorb the same quantity of CO2 from the air that was originally removed.
By leveraging the ocean to remove atmospheric CO2, the approach is highly scalable and cost-effective. Captura’s process is also unique in that it creates no by-products and doesn’t add anything to the ocean – it simply removes CO2 that the atmosphere then replaces.
Captura’s technology is progressing rapidly through our piloting program towards large-scale commercial deployment.
said Captura CEO Steve Oldham.
At AltaSea, Captura’s team will conduct technology development and ocean modeling work that will enable the company to validate and improve the efficiency of the pilot DOC system and guide feasibility studies for commercial facilities. It will provide a semi-contained environment to measure and monitor the resulting atmospheric CO2 drawdown and evaluate the effects of DOC on the marine ecosystem, including its potential for helping to mitigate ocean acidification.
