Oslo-based FLOCEAN has expanded its Series A round to $22.5 million, adding Xylem Inc. as a strategic investor alongside existing backers Burnt Island Ventures, Freebird Capital, Katapult Ocean, and Nysnø Climate Investments, with new participation from Ari Emanuel, Orion, Rypples, and Wellers Impact’s Water Unite Impact Fund, as well as the CEO of Asset Buyout Partners. The Norway-based company develops subsea desalination systems designed to leverage deep-ocean pressure to reduce energy needs and minimize onshore infrastructure. Flocean says the new funding will support the launch of its first commercial demonstrator plant, Flocean One, planned for 2026 at Mongstad, and help advance ongoing municipal and industrial water projects across several global regions.
Flocean develops subsea desalination systems deployed 400–600 meters below the surface, where natural ocean pressure can be used to reduce the energy intensity and infrastructure footprint of conventional desalination. The company reports that its approach cuts capital cost per capacity unit by up to 8x in Western markets, reduces energy consumption by roughly 50%, eliminates chemical pre-treatment, and avoids coastal brine discharge by diffusing waste deep below sensitive ecosystems.
“We’re not making an incremental improvement—we’re changing the fundamental economics of water,” said Alexander Fuglesang, Founder & CEO of Flocean. “Water-intensive industries from semiconductors to data centers to mining are increasingly constrained by water scarcity. They need solutions that can deploy faster, cost less, and operate more sustainably. That’s exactly what subsea desalination delivers.”
The newly raised capital will support the launch of Flocean One, positioned as the world’s first commercial subsea desalination demonstrator, scheduled to begin operations in 2026 at Mongstad Industrial Park.
The announcement comes alongside Flocean’s agreement with Alver Municipality in Norway to evaluate the company’s freshwater supply for industrial and municipal users and its potential integration into existing infrastructure. Flocean has been operating a long-term test site at Mongstad for the past year through its partnership with ABP, the site’s owner.
“We are excited to collaborate with Flocean on testing their groundbreaking water desalination technology,” said Nina Bognøy, Mayor of Alver Municipality. “Our municipality applauds bold efforts like this and we will work as a team to evaluate and consider Flocean’s offering for both local industrial users, as well as the municipal network.”
Beyond Norway, the company says it has secured early-stage agreements with water utilities in regions including the Mediterranean, Red Sea, and Indian Ocean, all of which face mounting resource constraints. Flocean plans to operate under a Build-Own-Operate model, selling water under long-term offtake agreements to municipal, industrial, and agricultural customers.
For Xylem, a Fortune 500 water technology company, the investment aligns with its broader efforts to scale emerging solutions in global water management. Flocean will also join the Xylem Innovation Labs Accelerator, gaining access to the company’s technical and commercial network.
“Flocean’s subsea desalination technology represents a bold leap forward in how we produce fresh water and address water scarcity — one of the most urgent challenges of our time,” said Snehal Desai, Chief Growth and Innovation Officer at Xylem. “As demand for water accelerates globally, we’re investing in breakthrough technologies that have strong potential to scale. This partnership reflects our commitment to solving water with innovation that empowers our customers and communities to build a more water-secure world.”
When launched, Flocean One is expected to produce 1,000 cubic meters of freshwater per day, with modular systems designed to scale substantially depending on local demand.
