Flocean also announced an agreement with Norway’s Alver Municipality to explore offering Flocean’s water to the Municipality’s industrial and consumer customers, and to assess its integration into existing water infrastructure. Flocean has already been desalinating water for 12 months at its test site at Norway’s largest offshore supply base,

Conventional Desalination Struggles to Keep Pace with Global Freshwater Demand
Global freshwater demand is rising sharply, driven by climate volatility, population growth, and industrial expansion. But conventional desalination infrastructure struggles to keep pace—constrained by multi-year permitting timelines, massive capital costs, and limited coastal land.
Flocean's subsea approach delivers a fundamentally different economic model. By moving desalination systems 400–600 meters below the water, the technology leverages the natural pressure of the ocean to reduce cost and deployment time:
- 7-8x lower capital cost per unit of capacity compared to conventional SWRO desal-plants in Western regions
- 50% reduction in energy consumption and greenhouse gas emissions
- 95% less coastal land use, reducing land acquisition and permitting delays
- 60% reduction in pre-treatment infrastructure, accelerating deployment
- Zero chemical pre-treatment required
- No toxic brine discharge, as chemical-free discharge occurs deep below sensitive habitats
"We're not making an incremental improvement—we're changing the fundamental economics of water," said
Flocean operates under a Build-Own-Operate model, selling water as a service to municipal and industrial clients under long-term, bankable offtake agreements spanning 15-25 years. The company has secured initial project agreements in multiple countries, including collaborations with utilities in the Mediterranean,
“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
Flocean also joins the
“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.”
Flocean One will produce 1,000 cubic meters of freshwater daily when it launches in 2026. The modular design enables systems to scale from 5,000 to 50,000 cubic meters per day, serving municipalities, industrial operations, and agricultural clients in over 90 water-stressed coastal markets globally.
