Low Carbon Ocean Alkalinity Enhancement Solutions

Low Carbon Magnesium Hydroxide Feedstock 

About Us

Our Vision and Mission

We are committed to building a platform that will advance the restoration of our oceans' natural balance, reverse the damaging effects of acidification on marine life and our climate, to leave a healthier planet for the next generation.

As a first mover in this space, we aim to provide the lowest carbon feedstock from the outset to ensure Ocean Alkalinity Enhancement can be deployed at scale and achieve meaningful climate impact.

Our Technology

Low Carbon Alkalinity, the essential element for Carbon Dioxide Removal

Our technology uses a low temperature cracking process to decompose Olivine.

Metals and Silica are extracted as Co-Products leaving low carbon Magnesium Hydroxide for Ocean Alkalinity Enhancement.

Low carbon Alkalinity is essential to achieve Carbon Dioxide Removal (CDR).

One tonne of Magnesium Hydroxide added to sea water will drawdown (capture) around 1.2t of CO2.

The portion of captured CO2 that is actually removed is mostly determined by the embodied carbon of the Magnesium Hydroxide feedstock.

At less than 100kg CO2e per tonne our feedstock has the potential to remove 1.1t of CO2.

That's over 90% of the theoretical maximum.

Key Benefits

Advantages of Our Solutions

Discover the benefits of our OAE technology:

Maximum Carbon Dioxide Removal Potential

High carbon dioxide removal efficency

At less that 100kg of CO2e/t Mg(OH)2 the Carbon Dioxide Removal potential is 90% of the theoretical maximum. 

High Permanence of CDR

Low secondary precipitation risk

Magnesium concentrations in sea water are well below saturation points. Magnesium Hydroxide can be added to seawater with little risk of triggering secondary precipitation of carbonates. 

Safe Levels of Alkalinity

Low risk of exceeding safe levels of Alkalinity 

In lab conditions, the maximum achievable pH that can be reached by adding Magnesium Hydroxide to seawater is around pH9.5. The effects of dilution and solubility rates will result in much lower peaks.

Low Toxicity Risks

Heavy metals are removed

Our process removes all metal from our raw material, Olivine, to produce pure Magnesium Hydroxide, thus reducing the complexity of environmental risk management processes.

Gigaton Scale-Up

Gigatonnes of Olivine Reserves

The raw material for our process is Olivine; the largest single reserve is estimated to be in excess of 1,400 Million Gigatonnes.
