Captura is a Caltech-founded technology company specializing in Direct Ocean Capture (DOC) of CO₂, using high-performance electrodialysis to remove carbon from seawater for permanent storage or reuse.[1][3][4][5] It serves the environmental and climate restoration industries by providing a scalable, verifiable CO₂ removal solution that boosts the ocean's natural carbon cycles without chemicals or by-products, targeting gigaton-scale deployment.[1][2][3] The company has demonstrated strong growth momentum through successful pilots—scaling 1,000x while meeting performance indicators—and is now advancing to commercial plants removing tens of thousands to millions of tons of CO₂ annually, leveraging existing ocean infrastructure like desalination plants and retired oil rigs.[1][4]
Powered solely by seawater and renewable electricity, Captura's systems feature proprietary ultra-efficient membranes for streamlined, low-cost operation, with backing from partners like Equinor, XPRIZE, Frontier, and the U.S. Department of Energy.[1][3][4][6]
Captura emerged from Caltech labs in 2021, based in Pasadena, California, with a mission to heal the climate at scale by harnessing the ocean's natural carbon sink.[2][3][5] Founders, guided by strict scientific research, studied ocean cycles to develop an electrodialysis-based DOC process that amplifies natural removal without environmental harm.[1][3] Key early milestones include the first pilot at Caltech’s Kerckhoff Marine Laboratory in 2022, a second-generation system at AltaSea in the Port of L.A. in 2023, and a third pilot at Hawai’i Ocean Science & Technology Park with Equinor in 2025, validating commercial readiness.[1][4]
Pivotal traction came from industry partnerships, such as Equinor's validation of the DOC system and DOE funding for offshore platform designs, propelling Captura from lab concept to large-scale commercialization.[1][4][6]
Captura rides the Direct Ocean Capture trend within carbon dioxide removal (CDR), addressing atmospheric CO₂ via the ocean's vast capacity amid rising demand for verifiable, scalable climate solutions.[1][3][4] Timing aligns with global net-zero goals, U.S. DOE's Carbon Negative Shot (<$100/tonne by 2032), and partnerships like Equinor for commercialization.[4][6] Favorable market forces include offshore renewables growth, repurposed infrastructure, and credits from XPRIZE/Frontier, positioning DOC as a complement to direct air capture for gigaton needs.[1][3][4]
It influences the ecosystem by pioneering industrial applications of electrodialysis, inspiring ocean-based CDR, and validating protocols that build buyer confidence.[1][4][5]
Captura is poised for commercial deployments in 2025-2026, starting with plants at tens of thousands to millions of tons CO₂/year, expanding to megaton-scale offshore platforms powered by renewables.[1][4] Trends like policy-driven CDR markets, offshore energy integration, and falling electrodialysis costs will accelerate growth, potentially capturing a major share of the ocean CDR niche.[1][3][6] Its influence may evolve by standardizing DOC protocols and enabling industrial CO₂ reuse, solidifying its role from Caltech spinout to climate infrastructure leader—harnessing the ocean to heal the climate at scale.[3][4]
Captura has raised $22.0M across 2 funding rounds. Most recently, it raised $10.0M Series A in April 2024.
