Giga-ton scalable Carbon Dioxide Removal Technology

Our Ocean’s Carbon Removal Power

The ocean is a massive sink for CO₂ as one-third of all CO₂ emissions end up in the ocean. Since the industrial revolution, the excess amount of CO₂ in the air has led to ocean acidification. The concentration of (dissolved) carbon in the ocean is more than 150 times higher than in the air. This makes the ocean a powerful source for CO₂ removal.

Electrochemical Direct Ocean Capture (DOC)

Direct Ocean Capture 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 alter the carbonate equilibrium of the existing dissolved carbon in water to enable CO₂ extraction in gas form, which is then permanently stored in geological formations or put into products such as concrete. We return the decarbonized water to the surface of the ocean, where it re-absorbs CO₂ from the atmosphere, bringing balance to climate and battling ocean acidification.

Our Products

The removed CO₂ can be stored away in a permanent way (Carbon Dioxide Removal, CDR), or it can be used/ converted to chemical/ fuels (Utilisation).

We remove and store CO₂ and sell carbon credits to compensate for irreducible emissions

CDR

The removed carbon can be stored permanently by sequestering it in underground geological formations or by mineralizing 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 company’s emissions or become a storage partner.

Green CO₂ as a valuable resource

Utilisation

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.

Frequently Asked Questions

  • CDR is necessary for net-zero CO₂ emissions. To limit climate change, the concentration of CO₂ in the atmosphere needs to be decreased fast. In addition to avoiding/reducing additional emissions, we need to remove (the already existing) CO₂ from the atmosphere. Net zero means huge declines in the use of coal, oil and gas. However, even if 90 % of the world’s energy comes from renewable sources by 2050, we still need 10.000.000.000 tons of CO₂ removal per year to reach net zero.

  • Oceans absorb one-third of the emitted CO₂. Ocean has 150 times more carbon (as dissolved) compared to the atmosphere and acts as a natural CO₂ absorbent from the atmosphere. Much less volume of the ocean’s surface needs to be treated compared to the DAC for the same CO₂ removal. Considering that 70 % of the earth is covered with ocean water, using the vast, available, cheap ocean as input facilitates CDR significantly.

  • We avoid altering the ocean chemistry and only remove the dissolved inorganic carbon (DIC) as gaseous CO₂. After DIC removal, the decarbonised ocean will be returned to the ocean surface. We work with environmental and marine experts to ensure the protection of ocean ecosystems.

  • Our technology has been fully demonstrated at laboratory scale. In 2025, our first pilot plant will start long-term operation using real sea water at North Sea, in the Netherlands. The North Sea is rather small, but from a biological perspective, it is highly productive. Thanks to inputs of alkalinity from rivers and sediments, the chemical buffering capacity of seawater is high at the North sea. This allows its waters to absorb more CO₂ from the atmosphere while resisting the resulting chemical changes.

  • Yes. By removing CO₂ from the ocean, we restore its pH and fight acidification at a local level.

  • In our electrochemical method, green electricity, membranes and seawater are needed. No added chemicals, high temperature or pressure is required.
