Global certification body DNV has recently endorsed Flocean’s innovative desalination approach, which has been shown to save 30-50% in energy compared to traditional systems after site-specific engineering is completed. This approval comes at a crucial time, as conventional desalination capacity is expected to double by 2032 to combat water shortages, but at the risk of a significant increase in carbon emissions.
Current desalination plants already contribute over 400 million tons of CO2 annually, a number that could double in the next decade with the onset of new projects. Energy is a key cost factor in desalination, accounting for a sizable portion of operational expenses. In countries like Cyprus, where desalination is the primary source of freshwater, the process generates 2% of the country’s total greenhouse gas emissions and consumes 5% of its power.
To address these challenges, Flocean launched the Flocean Zero project in November 2024 to validate their energy-efficient approach in practical settings. Initial data analysis has shown that deep ocean environments provide optimal conditions for high-efficiency desalination, with energy requirements significantly reduced.
By utilizing natural pressure and superior water quality, Flocean’s technology eliminates the need for energy-intensive pumping systems and pre-treatment processes, resulting in higher efficiency gains. With freshwater demand projected to outstrip supply by 40% by 2030, solutions like Flocean’s could play a pivotal role in ensuring water security while also meeting climate commitments on a global scale.
