Challenge signal
Extreme
Water access
Access to safe and reliable water services
2+ billion people lack safely managed drinking water services.
Challenge signal
Serious
Water scarcity
Lack of enough available water to meet demand during certain periods
4 billion people, nearly two-thirds of the global population, experience severe water scarcity for at least one month each year.
Challenge signal
Serious
Water stress
Significant depletion of available water supply resources
By 2040, 1 in 4 children will live in areas of extremely high water stress, where more than 80% of available supply is withdrawn.
Why now
Rising demand, coastal vulnerability, and a major untapped energy source
The opportunity sits where global freshwater demand, coastal need, and ocean-wave energy overlap.
~70%
Freshwater is used by agriculture and industry
Growing freshwater demand
Demand is outpacing supply globally
Population growth, industrial use, and climate pressure are increasing demand for resilient water supply solutions.
~2 TW
Global energy potential in ocean waves
Untapped energy source
Ocean waves are a constant, underused energy supply
Ocean waves are abundant, predictable, and still underused as a direct energy source for freshwater production.
~50%
Increase in desalination demand by 2050
Coastal and island vulnerability
Unlock scalable freshwater from ocean waves
Many water-stressed regions are coastal, but conventional desalination often depends on grid access, stable infrastructure, and high service capacity.
Havstraum operates at the intersection of water stress, coastal needs, and untapped wave energy.

Emerging wave-powered segment
Emerging opportunity with strong growth potential.
We enter through coastal and island applications, where offshore deployment delivers the highest value.
Current desalination limits
Ocean conditions expose the limits of conventional systems.
Desalination
Why desalination doesn't scale today
Havstraum is addressing the structural challenges that make conventional desalination difficult to deploy and maintain offshore. The goal is not just freshwater production, but a model built for continuous operation at sea.
01Reliability
Offshore Reliability Gap
Conventional desalination systems are difficult to keep stable and reliable in offshore conditions where salt, motion, corrosion, and load variation are constant.
OPERATIONS
02Power
Power Dependency & Carbon Footprint
Most plants depend on grid access or fossil-backed energy, which increases both operating cost and emissions in the places that often need freshwater the most.
ENERGY
03Environment
Environmental & Infrastructure Constraints
Large coastal facilities need stable infrastructure, permitting, and land access, which limits deployment in island, remote, and climate-stressed locations.
SITING
04Servicing
High Servicing Burden
Maintenance-heavy systems create downtime, logistics complexity, and cost, especially when specialist servicing is required far from shore-based support.
MAINTENANCE
Our Approach
Rethinking mechanical systems for ocean conditions
Havstraum is developing a wave-powered desalination concept focused on how energy is transferred, controlled, and sustained in marine environments. By rethinking mechanical systems for ocean conditions, we aim to enable more robust and long-lasting freshwater production offshore.
