Leveraging the Ocean's Carbon Removal Power
HOW IT WORKS
Our Direct Ocean Capture process
Our technology features a flow of ocean water passing through the facility, where water is treated to remove its carbon dioxide content. This decarbonized water is then returned to the ocean’s surface layer where it reacts with the atmospheric CO₂ to absorb an equivalent quantity of the original CO₂.
To meet the net zero carbon goals of 2050, sustainable, scalable, inexpensive technologies that fit in an electrified industry and have a small footprint are needed for carbon removal.
Our electrochemical Direct Ocean Capture technology:
Has a compact and flexible plug-and-play design that can be retrofitted into existing infrastructure and allow for low land use
Does not need any chemical or feedstock, as the ocean already acts as a massive natural CO₂ absorbent from the atmosphere
Is energy efficient and fully electrical, offering a cost-efficient and heat-free approach to do high-quality carbon removal at large scale
Our Process in 8 steps
Seawater is taken from the ocean surface within 50-100 m depth
A small fraction of the seawater stream needs to be pre-treated and filtered to enter the Bipolar Membrane Electrodialysis (BPMED)
Inside the Bipolar Membrane Electrodialysis (BPMED), a sufficient current density is applied that generates a sustainable pH-swing (i.e., acid and base production)
The produced acid is mixed with seawater to reach a mild acidic pH, and enable CO₂ degassing (the dissolved bicarbonate ions turn into dissolved CO₂ upon acidification)
Gaseous CO₂ is extracted from the acidified seawater portion.
The extracted CO₂(g) is then compressed and transported for storage or utilisation
The produced alkaline stream from the BPMED is added to the mild acidic stream for pH restoration
The decarbonised water with restored pH is discharged back to the ocean, where it will re-absorb CO₂ from the atmosphere, decreasing carbon dioxide concentration in the atmosphere within a couple of months.
OUR PRODUCTS
The removed Carbon Dioxide can be stored away in a permanent way (Carbon Dioxide Removal, CDR), or it can be used/ converted to chemical/ fuels (Utilisation)
CDR
We remove and store CO₂ and sell carbon credits to compensate for irreducible emissions
The removed carbon can be stored permanently by sequestering it in underground geological formations or by mineralising it into concrete. We will be partnering with European based storage parties to store our first tons of removed CO₂. We offer high quality carbon credits to neutralize your company's (irreducible) emissions. Neutralize your companies emissions or become a storage partner
Utilisation
Green CO₂ as a valuable resource
The removed carbon does not need to be seen as a waste product but rather as a valuable resource. Applications can be pivotal contributions in decarbonizing hard to abate industries. CO₂ can be used directly (for example: food, beverages, packaging, agriculture) or it can be converted into alternative fuels (e.g., green methanol), chemicals (e.g., ethylene, alcohols, formic acid, formate, syngas, urea) and other organic materials.
