Innovative Marine Startup Captura to Capture Carbon Dioxide from Pacific Ocean

In a groundbreaking initiative, marine-tech startup Captura is set to begin carbon dioxide extraction from the Pacific Ocean at Hawaii's Keāhole Point in 2025. This innovative approach involves pumping seawater through electrochemical systems to remove CO

, subsequently returning the treated water to the ocean, which will then absorb more atmospheric CO

.

Captura's pilot plant, located on a retired U.S. Navy barge at the Port of Los Angeles, has been operational for a year, successfully demonstrating the technology's potential to capture 100 tonnes of CO

2

annually. The upcoming facility in Hawaii aims to increase this capacity tenfold.

This project is part of a broader trend where startups are harnessing the ocean's natural carbon absorption capabilities to combat climate change. Captura's novel electrodialysis machine rearranges seawater molecules, allowing for efficient CO

capture. The initiative has garnered significant interest, with funding from major entities supporting marine-based carbon removal strategies.

As the world faces escalating carbon emissions, Captura's efforts represent a promising step towards utilizing ocean resources to mitigate climate impacts.
