COMPANY DESCRIPTION

Captura provides a scalable, low-cost Direct Ocean Capture (DOC) carbon removal solution, producing a measurable stream of CO2 for sequestration, using only seawater and renewable energy, with no other external additives or by-products produced. DOC requires no freshwater, has a minimal land footprint and can operate with intermittent power. The technology has been fully demonstrated at 100-tonne scale since November 2023. Captura is deploying a 1,000-tonne system in late 2024 while designing larger-scale commercial plants.

CORE INNOVATION

1) Lower Cost: No purpose-built air contactors or absorbents, widespread use of standard industrial equipment and ability to leverage off-peak/intermittent renewable electricity lowers costs. No disposal costs since no by-products generated. 2) Scalability: Use of oceans makes DOC deployable globally. Only inputs are renewable energy and seawater - no supply chain constraints. No temperature or humidity restrictions. No freshwater or material land use. 3) Ocean Health: Closed-loop process adds nothing to oceans. Potential co-benefit of ocean acidification mitigation.

CO2 CAPTURE

Captura’s Direct Ocean Capture (DOC) technology harnesses the ocean’s natural carbon removal powers to drawdown atmospheric CO2, using just renewable energy and seawater as inputs, with no ocean additives. DOC captures CO2 from surface oceans utilizing closed-loop electrodialysis, effectively making “more room” for oceans to draw down the same amount of CO2 from the atmosphere. In this way, removal of CO2 from the ocean results in subsequent removal of CO2 from the atmosphere.

CO2 SEQUESTRATION

Captura produces a measurable stream of CO2, compatible with multiple sequestration solutions worldwide. The CO2 from the 1,000-tonne system will be transported and durably stored at Northern Lights, a pioneering storage facility located in Oygarden, Norway with capacity for up to 5 million tonnes of CO2 annually. The CO2 is injected in a saline aquifer 2,600m under the seabed. Extensive testing and exploration confirmed the suitability of the reservoir for safe and durable CO2 storage.

CO-BENEFITS OR PRODUCTS

Captura DOC removes CO2 from oceans faster than the ocean can replace it with atmospheric CO2, resulting in less CO2 in oceans. This effect could help to mitigate ocean acidification and support ocean-dependent communities. The stream of CO2 that Captura produces can be durably and safely sequestered to generate high-quality carbon credits to help corporations reach critical Net Zero targets, or re-used to create low-carbon products such as green fuels, facilitating the energy transition.
