🎉 SeaO₂ wins Duurzame Dinsdag Pitch Competition 2025! 🎉

We are proud to share that SeaO₂ has been selected as one of the winners of the Duurzame Dinsdag pitch competition 2025!

Out of 186 submitted innovations, only seven were invited to pitch live in The Hague, and just three companies were chosen as winners. We are honoured to be among them.

For us, this recognition is more than a prize—it’s a strong signal that marine Carbon Dioxide Removal (mCDR) is gaining the visibility and support it deserves. At SeaO₂, we are developing electrochemical Direct Ocean Capture, a breakthrough approach that uses only renewable electricity and seawater to remove CO₂ from the ocean—and by extension, from the atmosphere. The result is a pure CO₂ stream that can be permanently stored or reused in sustainable products.

Our mission is clear and urgent: 🌊Protect our planet from getting warmer and warmer by lowering CO₂ concentrations in the ocean and air

Winning Duurzame Dinsdag gives us renewed energy to push forward. It underlines the importance of scaling solutions that tackle the climate crisis while safeguarding ocean health—two challenges that are deeply interconnected.

We want to extend a big thank you to the organisers, jury, and fellow innovators for the inspiration. Being on stage with so many dedicated changemakers shows that together, we can move the needle on climate action. 🌏

Special thanks to Duurzame Dinsdag, Harm Edens, Sophie Hermans, Maurits Groen, and our co-finalists including RIFT, Grassa, Melvin Sieben, Lenteland, and many others driving the sustainability transition forward.

This milestone motivates us to keep building momentum towards gigaton-scale climate impact. 🚀
