Dawsonite Diver is a research and invention project focused on reversing ocean acidification by removing carbon dioxide from seawater and converting it into a stable mineral form. Ocean acidification is driven by increased atmospheric CO₂, as the ocean absorbs 25% of the emissions. In the water, the CO₂ forms carbonic acid and disrupts marine ecosystems while also “filling up” the ocean’s capacity to act as a carbon sink.

Our solution is a boat-attachable carbon capture device that uses electrolysis to extract CO₂ from seawater and convert it into dawsonite, a stable fire-retardant mineral. The core idea is to make carbon removal accessible to a range of boat owners, enabling them to capture carbon on everyday trips and contribute to scalable carbon sequestration. The project earned national and international recognition and was accepted into the MIT Sandbox.
