What Flocean does

Flocean AS, founded in 2024 and headquartered in Oslo, Norway, develops subsea seawater desalination systems deployed at 400-600 meters depth. The company was spun out of FSubsea, a 5-generation Norwegian subsea engineering family business with over 100 years of subsea processing experience. Flocean's core technology platform, branded Flocean Deep, leverages natural hydrostatic pressure at depth (40-50 bar) to drive reverse osmosis without conventional high-pressure feed pumps, reducing energy consumption by 40-50% relative to coastal desalination plants. Modular subsea pods produce 5,000-7,500 m³/day each and scale to 50,000 m³/day via 10-pod configurations. Flocean One, the company's first commercial-scale deployment producing 1 million liters per day, achieved 'first water' in June 2026 at 500 meters depth off Norway's west coast.

Flocean operates under a Build-Own-Operate model, selling water as a service to municipal, industrial, and agricultural clients through long-term bankable offtake agreements spanning 15-25 years. Target customers include water-stressed islands and coastal communities, water-intensive industries (semiconductors, data centers, mining, manufacturing), and agricultural operations in Mediterranean, Red Sea, Indian Ocean, Middle Eastern, and Americas geographies. Named engagements include an agreement with Alver Municipality in Norway and an MOU with Malé Water and Sewerage Company (MWSC) in the Maldives via a development agreement with WaterConnect. The company reports 15+ projects in active development and a theoretical addressable footprint of 90+ water-stressed markets with deep-water shoreline access.

Flocean has raised approximately $31.5 million across two funding rounds, with the $22.5 million Series A extension in November 2025 led by Xylem Inc. as strategic investor, alongside Burnt Island Ventures, Freebird Capital, Katapult Ocean, Nysnø Climate Investments, and individual investors including Ari Emanuel. The company joined the Xylem Innovation Labs Accelerator as part of this partnership. Flocean has received TIME Best Inventions of 2025, Fast Company Most Innovative Companies 2026, WEF Water Resilience Challenge Winner (2026), and XPRIZE Water Scarcity semifinalist (2026) recognition. Founder and CEO Alexander Fuglesang leads the company, with a board chaired by Curtis W. Huff (Owner of Freebird Partners) and directors from Burnt Island Ventures and Bridgewater Associates/Carlyle Group alumni. Strategic advisors include senior figures from Suez, Scatec, Thommessen, Resonance Asset Management, and McKinsey.

Core offering

Flocean designs, manufactures, owns, and operates modular subsea desalination systems that are deployed on the seafloor at 400-600 meters depth to produce freshwater from seawater using natural hydrostatic pressure. The company sells water as a service under a Build-Own-Operate model via long-term (15-25 year) bankable offtake agreements to municipalities, industrial operators, and agricultural clients in water-stressed coastal regions.

Product overview

Flocean offers a unified subsea desalination solution centered on its Flocean Deep technology platform, which includes the Flocean One commercial system and modular Flocean Desal Pod units. Flocean Deep is the core patented technology that deploys modular desalination pods on the seafloor at 400-600 meters depth, using natural ocean pressure to power reverse osmosis. Flocean One represents the company's first commercial-scale deployment of this technology, producing up to 1 million liters of freshwater daily. The Flocean Desal Pod serves as the modular building block, with each pod capable of producing up to 5,000 m³/day, scalable to 50,000 m³/day through multi-pod configurations. The company operates under a Build-Own-Operate model, selling water as a service to municipal and industrial clients under long-term offtake agreements spanning 15-25 years, targeting water-stressed coastal and island regions across 90+ markets globally.
