About us

SeaO2 is a Dutch Ocean Carbon Removal company committed to addressing climate change through removing CO2 from the atmosphere at gigaton-scale, harnessing the potential of the oceans.

SeaO2 is pioneering a transformative solution to address the critical challenge of achieving Net Zero by 2050, a goal to prevent global warming from exceeding 1.5ºC above 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/yr remains from the hard-to-abate sectors, which must be addressed through Carbon Removal, often called “Negative Emissions”.

SeaO2's solution, Direct Ocean Capture (DOC), relies solely on renewable electricity and seawater to extract CO2 from the surface of seawater and consequently from the atmosphere. The process uses electrochemistry and vacuum to shift the carbonate equilibrium of the existing dissolved carbon in water in order to enable extraction of gaseous CO2, which is then permanently stored in geological formations or utilised into products such as concrete or alternative fuels like green methanol. The strength of this approach lies in its scalability and cost-effectiveness. By leveraging the vast scale of the ocean and utilising offshore infrastructure, it avoids land use. Additionally, carbon is 150 times more concentrated in the ocean than in the air, making CO2 extraction more efficient. The process is fully electrical, heat-free, and requires no rare feedstock, all of which contribute to its economic viability.

The company was founded in 2021 from research at TU Delft and today we have a prototype in our R&D facility located at The Afsluitdijk, on the Dutch coastline. We are currently building our Pilot facility. Our goal is to reach the Megaton scale by 2030 and Gigaton scale by 2045

Roles and Responsibilities

After having shown the feasibility of the technology in prototype scale, SeaO2 is currently designing and building its 250 tCO2/yr removal capacity pilot in the Netherlands. We are looking for a practically oriented "research and development" engineer, to operate and improve the prototype and the pilot plant installation with the aim of reducing the energy consumption of the process and increasing its scale. The experiments are run using the prototype installation located at the Afsluitdijk, while the pilot will be located in the north of Groningen.
