Electrolytic seawater mineralization projects are a carbon-removal project type within the ocean & water segment of the carbon market. They involve electrochemical seawater processes that generate alkalinity and/or carbonated minerals to durably store carbon. In practice, electrochemical processes enhance carbon uptake and then route carbon into durable mineral or dissolved storage. Common project configurations include Electrolytic seawater mineralization systems.

Electrochemical systems can be precisely engineered, but their net benefit depends on energy intensity, product handling, and robust carbon accounting. Ocean-based pathways are developing quickly and can be scientifically compelling, but they generally require especially careful MRV, strong ecological safeguards, and a clear accounting framework for permanence and reversals. For buyers and program designers, the most important diligence questions are: How carbon-intensive is the electricity supply? Are seawater chemistry impacts and storage measurements robust?
