Harnessing the
ocean to heal
the climate
Captura technology provides a simple, streamlined process for large-scale Direct Ocean Capture of carbon.
Technology
A scalable
solution for
carbon removal
Powered by Captura’s high-performance electrodialysis technology, our Direct Ocean Capture process removes CO₂ from seawater and amplifies the ocean’s natural removal of carbon from the atmosphere — all with no additives or by-products. To see the technology in action, take a virtual tour of our 1000 ton-per-year pilot plant in Hawaii.
Ocean Health
Ocean
above all
It’s enormous, powerful, available — and it’s ours to care for. Captura’s system boosts natural cycles, while putting ocean health first.
Solutions
Driving climate & industrial innovation
Captura’s technology unlocks powerful sustainability solutions — from removing and reusing excess CO₂ to delivering high-performance electrodialysis across a range of markets, including direct lithium extraction, desalination and wastewater valorization, energy storage, and electrochemical carbon capture and removal.
