The plant, housed at the Hawai’i Ocean Science and Technology Park, was developed in partnership with multinational energy firm Equinor, and is capable of extracting 1,000 tonnes of CO2 per year directly from seawater.
This marks the third and final pilot in Captura’s development programme, paving the way for full-scale commercial deployment of its DOC technology. Unlike traditional carbon capture methods, DOC leverages the ocean’s natural ability to absorb atmospheric CO₂, enhancing this process without producing waste or requiring additional feedstock.
The Hawai’i facility builds on successful trials at Captura’s two previous pilot plants in Los Angeles, validating the scalability of its modular technologies. The company is now advancing plans for its first commercial-scale plant.
The CO₂ captured at the Hawai'i plant can be directly sequestered, used as a feedstock to produce renewable fuels, or utilised by industries that require CO2. Captura’s technology will also be offered to local industries, such as aquaculture, which seek to lower their carbon footprint.
"Captura’s journey from lab-scale testing to our third technology demonstration in just three years is a testament to the scalability of our solution. This facility in Hawai’i is the last milestone before we move to widespread commercial deployment of DOC technology. Its rapid installation and commissioning in just over two months demonstrates how our simple, modular design is ready to be scaled quickly to help address the urgent climate and energy challenge," said Steve Oldham, CEO of Captura, in a press release
