What specific problem are you solving?
SeaO2 is pioneering a transformative solution to address the critical challenge of Negative Emissions, needed for achieving Net Zero by 2050, a goal to prevent global warming from exceeding 1.5ºC over pre-industrial levels. As the IPCC (Intergovernmental Panel on Climate Change) published on their 2018 report, despite the aggressive pathways outlined for reducing emissions and decarbonizing industries, a substantial residual emission of at least 10 Gigatons remains (i.e., from the hard-to-abate sectors), a significant fraction of the current 40-50 Gigatons of global emissions. Reaching Net-Zero is impossible, unless in addition to decarbonisation, CO2 is also removed from the atmosphere, also often called “Negative Emissions”.
What is your solution?
At SeaO2, we remove the excess atmospheric CO2, to enable Net-Zero. Our approach harnesses the vast potential of the world's oceans, which cover 70% of the Earth's surface and already absorb a third of all emissions. This marine environment offers a unique advantage, as carbon is 150 times more concentrated in seawater than in the atmosphere, making CO2 extraction both more efficient and cost-effective compared to e.g., Direct Air Capture.
SeaO2's solution, Direct Ocean Capture, relies solely on renewable electricity and seawater to extract CO2 from the surface of seawater and consequently from the atmosphere in a scalable and cost-effective way. The process uses electrochemistry and vacuum to shift the carbonate equilibrium of the existing Dissolved Inorganic Carbon in water to enable CO2 extraction in gas form. The captured CO2 can then be stored away (e.g., underground) or utilised (as feedstock, directly or after conversion to valuable products).

Who does your solution serve, and in what ways will the solution impact their lives?
SeaO2’s work addresses climate change at its root by directly removing CO₂ from the atmosphere—a critical solution since only Negative Emission technologies can reverse existing emissions. This effort benefits everyone, but especially communities most vulnerable to climate impacts, such as low-lying coastal areas, small island nations, and regions prone to extreme weather. These populations are often underserved in terms of access to effective climate solutions.
Our technology delivers both carbon and non-carbon benefits. By removing CO₂ at gigaton-scale, we help stabilize global temperatures, protect ecosystems, and support long-term climate resilience. Our process also contributes to ocean de-acidification by releasing CO₂-depleted water with a slightly higher pH, helping restore marine ecosystems that are essential to coastal livelihoods.
Additionally, SeaO2's strong focus on Monitoring, Reporting, and Verification (MRV) enhances ocean observation, improving knowledge and protection of marine environments in areas that are often under-monitored.
Finally, our activities generate economic opportunities within the blue economy, creating jobs and supporting sustainable development in coastal regions.
By combining cutting-edge climate action with tangible benefits for vulnerable communities, SeaO2 empowers people and ecosystems alike to thrive in a changing climate, supporting a more resilient and equitable future.
