A breakthrough in ocean-based carbon capture technology now enables removal of 1 million tons of CO2 annually at costs below $100 per ton—making large-scale carbon removal economically viable for the first time.
🌊 Technology Metrics
How Ocean Capture Works
The system enhances natural ocean carbon absorption. Electrochemical processes increase seawater alkalinity, allowing the ocean to absorb more atmospheric CO2. The captured carbon becomes stable bicarbonate minerals—permanent, safe storage.
“The ocean already absorbs 25% of human CO2 emissions naturally. We’re simply accelerating and enhancing this process. It’s working with nature, not against it.”
— Dr. Ken Caldeira, Carnegie Climate Science
System Components
- Electrochemical Cells: Split seawater into acid and base streams
- Alkalinity Enhancement: Return base to ocean, increasing absorption capacity
- Mineral Carbonation: CO2 becomes stable calcium/magnesium carbonate
- Renewable Power: Solar and wind provide process energy
- Monitoring Network: AI-driven optimization of ocean chemistry

🗓️ Scaling Timeline
🏢 Corporate Buyers
Microsoft, Google, Stripe, and 200+ companies have pre-purchased over $1 billion in carbon removal credits. This corporate demand is financing rapid scaling of ocean capture technology.
Environmental Safeguards
- Marine Life Monitoring: Extensive ecological impact studies ongoing
- Alkalinity Limits: Changes kept within natural variation ranges
- Distributed Operations: Small changes across vast ocean areas
- Reversibility: Process can be halted with natural recovery
The Scale of the Challenge
Humanity emits approximately 40 billion tons of CO2 annually. Even removing 10 billion tons by 2050 only addresses part of the problem. Ocean capture is one tool in a portfolio that must include emissions reduction, direct air capture, and ecosystem restoration.
Ocean carbon capture transforms the climate crisis equation. Combined with aggressive emissions cuts, large-scale removal offers a pathway to actually reversing atmospheric CO2 increases—turning climate change from irreversible disaster to manageable challenge.
