Equatic, a Los Angeles-based startup, has developed an innovative ocean-based carbon removal system that not only captures carbon but also produces green hydrogen using renewable energy sources like wind or solar. The company's process involves pumping seawater into an electrolyzer, which separates the water into hydrogen, oxygen, acid, and an alkaline slurry for carbon capture. This dual-purpose approach has garnered significant attention in the battle against the climate crisis. Equatic is scaling its technology through pilot plants in Los Angeles and Singapore, with plans for larger commercial-scale plants in Singapore and Quebec. The company aims to capture 4,000 tonnes of CO2 and produce 100 tonnes of hydrogen annually in its upcoming plant in Singapore. However, Equatic faces scrutiny over its energy use and potential environmental impact, especially in terms of disrupting marine ecosystems. While Equatic's supporters emphasize the vast storage potential of oceans for carbon removal, skeptics raise concerns about the risks posed by large-scale marine CO2 removal, such as impacts on ocean chemistry, ecosystems, and food security. The company plans to monetize its efforts through carbon credits and has attracted pre-purchase agreements with companies like Boeing. Despite the ongoing debate over the effectiveness and impacts of ocean carbon removal technologies, Equatic remains optimistic about the future potential of its plants in removing millions of tonnes of CO2 annually. The company highlights the importance of addressing legacy CO2 in the atmosphere and aims to ensure environmental soundness through adherence to global standards and ongoing monitoring.
