Who’s Who in Tech: Equatic Is ‘Sinking’ in the Ocean

Why It Matters

Equatic’s dual‑output model could lower the cost barrier for large‑scale carbon removal while supplying green hydrogen, addressing two critical climate‑tech markets simultaneously.

Key Takeaways

• Equatic raised $11.6M Series A led by Temasek and Kibo
• Targets 100‑kiloton CO₂ removal facility producing green hydrogen
• Uses seawater electrolysis to generate base that captures atmospheric CO₂
• Onshore plant provides carbon data for compliance across jurisdictions

Pulse Analysis

Equatic’s approach taps the ocean’s natural ability to absorb carbon, but adds a high‑tech twist: seawater electrolysis powered by cheap renewable electricity. By splitting seawater into hydrogen, oxygen, acid and base, the process creates a carbon‑negative loop—base reacts with atmospheric CO₂, while the resulting green hydrogen can be sold as a clean fuel. This integration of carbon capture and value‑added product generation differentiates Equatic from traditional CCS projects that rely on costly geological storage and offer no revenue stream beyond carbon credits.

Regulatory compliance is another pillar of Equatic’s value proposition. While the ocean itself is a free carbon sink, companies increasingly need verifiable emissions data to meet tightening climate policies worldwide. Equatic’s on‑shore plants embed monitoring and reporting capabilities, delivering the granular carbon‑removal metrics demanded by carbon markets and corporate sustainability programs. This data‑rich architecture not only satisfies auditors but also opens pathways for monetizing carbon offsets, making the business model more resilient in a market where transparency is paramount.

The broader climate‑tech landscape is witnessing a surge of capital toward renewable energy and carbon‑removal solutions, driven by falling solar and wind costs and rising electricity demand across sectors—from AI data centers to electric vehicles. Equatic’s funding round, led by climate‑focused investors such as Temasek’s Catalytic Capital, signals confidence that ocean‑based removal can scale affordably. If the company meets its 100‑kiloton target, it could set a benchmark for cost‑effective, dual‑purpose climate infrastructure, prompting further investment and policy support for similar hybrid technologies.
