Why a wave-powered municipal water supply?

Coastal and island water authorities face a specific convergence of pressures: growing demand, declining rainfall-fed surface and groundwater reserves, grid instability, high fuel import costs, and increasing exposure to extreme weather. Conventional desalination addresses the supply problem but adds new dependencies on grid power and imported fuel — costs and vulnerabilities that transfer to the water tariff and to the communities who pay it.

BlueDesal’s wave-powered approach decouples freshwater production from fuel and grid infrastructure. For communities where those inputs are expensive, unreliable, or both, this is a structural advantage — not merely an environmental preference.

Designed for PPP, DBOM, and DBFOMT delivery

No diesel fuel cost embedded in the water tariff

Continues operating during grid outages — critical for resilience

Modular scale-up matches phased capital deployment and financing tranches

Compatible with IDB, World Bank, and DFI-financed project structures

Aligned with national Net Zero and climate resilience commitments

Supports compliance with WHO Drinking Water Guidelines

Regional and Island Focus

For example, the Eastern Caribbean is one of the world’s best-matched geographies for wave-powered desalination: consistent Atlantic swell, high diesel and electricity costs, severe water scarcity, and island communities beyond the reach of mainland grid or pipeline infrastructure.

Strong wave resource

The Eastern Caribbean receives consistent North Atlantic swell year-round, with significant wave heights typically between 1 and 3 metres along exposed coastlines. This provides a reliable mechanical energy input without the intermittency of solar or wind.

💰

High fuel cost environment

Many Caribbean islands import diesel at prices significantly above global benchmarks. Eliminating fuel from the water production cost equation directly reduces the tariff required to sustain and service a desalination facility.

Built for PPP and project-financed procurement

BlueDesal is structured to participate in government water infrastructure procurement under a range of delivery models.

DBOM

Design-Build-Operate-Maintain
BlueDesal designs and builds the wave-powered production array; a separate finance and asset ownership structure holds the infrastructure. Suitable for government-capital or DFI-funded projects.

DBFOMT

Design-Build-Finance-Operate-Maintain-Transfer
BlueDesal participates as technology provider and operator within a private-sector consortium that raises project finance against a long-term water purchase agreement.

Phased Feasibility → Deployment

For early-stage procurements, BlueDesal recommends separating site validation and demonstration from the full delivery commitment. This reduces risk for both parties and generates the engineering data needed for bankable project finance.

Consortium Participation

For large-scale sites requiring EPC, SWRO, marine, environmental, and O&M capabilities beyond BlueDesal’s current team, BlueDesal participates as technology provider within a delivery consortium that packages all required disciplines.

IDB eligibility and DFI compatibility

BlueDesal’s technology and delivery approach is designed to be compatible with Inter-American Development Bank, World Bank, and other development finance institution procurement and environmental standards. We welcome discussion with government counterparts about eligibility, procurement pathway, and required documentation at any stage.
