Why It Matters

The ocean has absorbed over 30% of anthropogenic CO2, leading to ocean acidification and threatening marine ecosystems, including coral reefs and shellfish, impacting global fisheries and biodiversity. Mainstream DOCC could see floating platforms or coastal facilities actively scrubbing CO2 from vast quantities of seawater, helping restore ocean pH and supporting marine life. Companies developing electrochemical systems, as well as coastal communities, stand to gain, while industries contributing to ocean acidification might face increased pressure for remediation. The primary technical hurdles are energy efficiency, scalability, and ensuring no harmful byproducts are released back into the ocean. Pilot and demonstration projects are anticipated within 5-10 years, with substantial deployment within 20-30 years. Startups like Ebb Carbon, Captura, and academic consortia are at the forefront of this emerging field. A less-considered impact is the potential for DOCC to decouple carbon removal from land-use constraints, making it a viable option for island nations or coastal megacities.
