Global Ocean Carbon Removal Market Size is valued at USD 638.9 Mn in 2024 and is predicted to reach USD 3435.3 Mn by the year 2034 at an 18.4% CAGR during the forecast period for 2025-2034.
Ocean Carbon Removal (OCR) refers to a range of innovative methods and technologies designed to enhance the ocean's natural ability to absorb and store atmospheric CO?, addressing the urgent need for large-scale carbon sequestration. These include DOC-direct ocean capture (direct seawater electrochemical removal of dissolved CO?), marine algal cultivation (macroalgae absorb CO? during photosynthesis and can provide biofuels as well as other products), and ocean alkalinity enhancement (addition of alkaline substances into seawater to enhance its ability to absorb more CO?). These methods would tap into the natural role the ocean has played-the largest carbon sink on Earth-to provide scalable solutions to address climate change impacts while fixing problems like ocean acidification.
The applications of OCR technologies vary from climate mitigation, such as helping to achieve set international climate targets by extracting CO? from the atmosphere, to restoring ocean health by lowering acidity for more robust marine ecosystems like coral reefs. Captured CO? can also assist industrial uses, such as the generation of synthetic fuels or neutralization of waste. Projecting to remove 100–1000 gigatons of CO? during this century, IPCC: the future application of OCR stands as a veritable complement to traditional emission reduction strategies, enormously harnessing the ocean's vast potential for carbon sequestration.
The Ocean Carbon Removal market is segmented by technology. By technology the market is segmented into direct air capture, biochar, enhanced mineralization, ocean alkalization, others.
Direct Air Capture (DAC) is a key driver in the Ocean Carbon Removal (OCR) market, integrating innovative technologies with oceanic systems to enhance carbon dioxide (CO?) sequestration. Recent developments of direct air capture include adaptation of atmospheric capture techniques for dissolved CO? in seawater utilizing electrochemical processes for removal. Although historically expensive, technologies are reducing DAC costs to a level of $100 per ton, making it easier to deploy on the open ocean while not competing for land. Increased regulatory support and investment, in addition to companies like Global Thermostat and Captura, is picking up its pace of adoption. Moreover, DAC enhances oceanic carbon storage, complementing natural processes by alleviating ocean acidification while delivering a vital, multi-faceted solution for climate mitigation.
Ocean Carbon Removal market is led by North America and the United States, mainly because of large investments in this region, innovative strategies by the companies, and a somewhat conducive regulatory environment. The U.S. Department of Energy has been extremely prompt in investing large funds, such as the $36 million in marine carbon dioxide removal projects. The region is home to key players like Brilliant Planet, Captura, and Ebb Carbon, besides research hubs and academic collaborations that drive the innovation of technology. Favorable regulations and climate action policies push the industries towards carbon removal solutions. These factors ultimately help North America move ahead as a leader in OCR advancements while accelerating growth in its market.
