Restoring the ocean's role as Earth's climate stabiliser.
Earth's largest carbon sink is in decline.
The ocean is Earth's largest active carbon sink. It absorbs around a quarter of all human CO2 emissions and has done so for centuries.
That service is now in decline. As CO2 dissolves into seawater it forms carbonic acid. Ocean pH has fallen by roughly 0.1 units since pre-industrial times — a 30% increase in acidity. Higher acidity weakens shell-forming organisms, disrupts marine ecosystems, and slows the rate at which the ocean can keep absorbing CO2.
Left unchecked, this becomes a feedback loop: more atmospheric CO2 drives more acidification, which reduces the ocean's capacity to remove CO2. Ocean restoration is not a side benefit of climate action — it is part of the climate solution itself.
A world where the ocean is once again Earth's climate solution.
No longer a victim of climate change, but one of its most powerful answers.
Help rebalance the climate — and restore marine ecosystems.
By neutralising excess ocean acidity and strengthening the ocean's natural ability to safely absorb and permanently store atmospheric CO2 at gigaton scale.
Three lines on how we get there.
The goal
Transform the ocean from a victim of climate change back into a climate stabiliser, through responsible planetary stewardship.
The method
A sustainable electrochemical process powered by seawater, renewable energy, and abundant alkaline minerals, accelerating Earth's natural carbon cycle.
The impact
A scalable, low-cost, measurable climate solution that removes atmospheric CO2 while supporting healthier marine ecosystems.
Why we are building the demonstration first.
Ocean alkalinity enhancement is a serious intervention in a complex marine system. Before we deploy at commercial scale, we need to understand exactly what our process does to the local environment.
Project Alkalion — our demonstration, a modular, containerised unit now in preparation — is purpose-built to study the effects of our process on local sea life. The research is conducted in partnership with the University of Málaga. The results will directly inform the design, siting, and operating parameters of Ocean Ionics One and every facility that follows.
We are committed to ocean alkalinity enhancement that is measurable, monitored, and ecologically responsible. CO2 removal that damages the ocean is not a climate solution.
