Carbon negative. Ocean positive
Ocean Ionics permanently removes atmospheric CO2 and restores ocean chemistry — using seawater, renewable electricity, and abundant minerals.
An electrochemical cycle that closes itself.
The ocean has long been Earth's largest carbon sink — absorbing roughly a quarter of human CO2 emissions. That service has come at a cost: rising ocean acidity is weakening marine ecosystems and reducing the ocean's natural ability to absorb more CO2.
Ocean Ionics develops an electrochemical process that helps reverse this. We generate alkalinity from seawater and return it to the ocean, where it neutralizes excess acidity and enhances the ocean's natural capacity to absorb and permanently store atmospheric CO2. The acidic by-product is safely neutralized on land using abundant alkaline minerals.
The result is permanent CO2 removal, healthier ocean chemistry, no waste streams to manage, and a path to gigaton-scale impact at carbon prices in line with existing emissions markets.
From pilot to first commercial facility.
Our process is currently validated in the laboratory at relevant operating conditions (TRL 5). The next step is Project Alkalion — a modular, containerised pilot, 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 move the technology to TRL 6.
Beyond the pilot, 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.
Building the climate solution the ocean already wants.
