OCEAN IONICS
Restoring ocean resilience

Carbon negative. Ocean positive.

Ocean Ionics restores ocean health and permanently removes atmospheric CO2 — using seawater, renewable electricity, and natural minerals.

What we do

A scalable salt-conversion platform.

Developing a scalable salt-conversion platform that simultaneously restores ocean health and removes carbon.

The ocean is Earth's largest natural carbon sink, absorbing approximately one-quarter of humanity's annual CO2 emissions. But this vital service comes at a cost: increasing ocean acidification is weakening marine ecosystems and reducing the ocean's capacity to continue absorbing carbon.

Ocean Ionics is developing an electrochemical salt-conversion platform that transforms dissolved seawater salts into alkaline and acidic streams. The alkaline stream is returned to the ocean, where it restores alkalinity, counteracts acidification, and enhances the ocean's natural ability to absorb and permanently store atmospheric CO2. The acidic stream is fully neutralised on land using abundant alkaline minerals, creating valuable, low-carbon products.

The result is a scalable platform for permanent carbon removal that simultaneously restores ocean health and enables gigaton-scale climate impact.

Ocean Ionics — process overview The process spans two domains. In the ocean and atmosphere, restored alkalinity draws atmospheric CO2 across the air-sea interface and stores it as dissolved bicarbonate and carbonate. On land, a facility draws seawater from the ocean and uses renewable electricity for salt conversion, producing an alkaline stream returned to the ocean and an acidic stream that is neutralised on land with abundant alkaline minerals.

Where we are

From Demonstration to first commercial facility.

Our process is currently validated in the laboratory at relevant operating conditions. The next step is Project Alkalion — a modular, containerised demonstration, now in preparation, with the site and schedule being finalised. Designed in partnership with the University of Málaga to study the effect of our process on sea life, it is built to demonstrate the technology in the real ocean environment.

Beyond the demonstration, Ocean Ionics One will be our first commercial plant — designed to remove 5,000 tonnes of CO2 per year, powered fully by on-site solar. We are speaking with family-office investors and European subsidy partners.

The ocean already removes a quarter of humanity’s CO2 emissions. Our job is to restore its capacity to keep doing it — permanently, measurably, and without waste. Ocean Ionics · Ocean Alkalinity Enhancement
