Powered by nature,
backed by science
Captura began with a bold mission: to harness the power of the ocean to heal the climate.
Born out of rigorous research at Caltech, our founders achieved breakthroughs in bipolar membrane electrodialysis, unlocking a more efficient way to separate and manage ions in salt solutions. By pairing this innovation with the ocean’s natural carbon cycle, we developed Direct Ocean Capture: a simple, scalable solution designed to remove significant quantities of CO₂ from the upper ocean and atmosphere.
Today, our electrodialysis technology extends beyond carbon removal. From our production facility in Pasadena, California, we manufacture high-performance membranes and electrodialysis stacks to power both our Direct Ocean Capture technology and a range of sustainability-driven industrial applications.
Guided by science and environmental stewardship, we are committed to delivering solutions that restore the climate and strengthen the systems that power modern life. From carbon removal to critical resource and energy applications, Captura is harnessing the power of the ocean and science to drive a resilient, net-negative future.

“Equinor Ventures is committed to investing across a menu of scalable carbon removal technologies. Direct Ocean Capture presents a compelling space for Equinor to leverage its offshore competence. We look forward to working with Captura to help catalyze its technology and business.”
Lars Klevjer Acting Managing Director of Equinor Ventures -
“Captura’s ocean carbon capture represents an innovative and cost-effective approach to reducing atmospheric CO2. It can also be integrated with desalination infrastructure which is already deployed at large scale in Saudi Arabia. We are excited to support Captura to commercialize this technology.”
Bruce Niven Executive Managing Director of Strategic Venturing at Aramco Ventures -
“Captura has fast become one of the most promising carbon removal companies on the market by leveraging the world’s greatest natural carbon sink, the ocean. Of all the solutions we’ve seen, Captura stood out, both on technology and track record of delivery. We are thrilled to partner with Steve, CX, Harry and the Captura team as they build commercial, gigaton scale, sub-$100 carbon removal solutions at a fraction of the capital cost of competing approaches.”
Ed Phillips Partner at Future Planet Capital -
“As Hitachi continues to expand in new, promising markets, Captura’s direct ocean carbon capture platform represents both an important growth area and a pathway for continued commitment to Hitachi’s mission of powering social good.”
Masakazu Aoki Executive Officer, EVP and General Manager, Connective Industries Division, Hitachi, Ltd. -
“Climate change is the biggest existential threat to humankind. Wildfires, global droughts, and record hurricanes are just the beginning. We’re serious about building large-scale carbon removal infrastructure to save our planet, and Captura’s scalable, durable and measurable technology stood out as a clear choice for Deep Sky’s first official technology partnership.”
