What if our best hope for large-scale carbon removal isn’t on land—but deep below the ocean’s surface?
In this episode of the Climate Confident podcast, I’m joined by Ori Shaashua, Co-founder and Chief Commercial Officer at Gigablue, to explore the cutting edge of marine carbon removal (mCDR). Gigablue’s innovative MCFS (Marine Carbon Fixation and Sequestration) method uses phytoplankton and gravity—not high-energy tech—to permanently sequester CO₂ in ocean sediment for thousands of years.
We cover:
👉 Why the ocean is the planet’s largest carbon sink
👉 How Gigablue’s system works—and why it’s cost-effective
👉 The importance of MRV (Measurement, Reporting & Verification) in building trust
👉 How scalable marine carbon removal really is—and what’s needed next
👉 Why 2025 could be the tipping point for mCDR
This isn’t just theory. Gigablue has already landed the largest ocean-based carbon removal offtake deal to date, and they’re scaling fast—with plans to reach gigaton-level removals by 2035.
If your company is exploring net zero strategies, high-durability carbon credits, or just wants to understand how climate tech is evolving beyond forests and DAC, this episode is for you.
