Water Scenarios: Global Desalination Futures
Water Scenarios: Global Desalination Futures
Desalination futures are being shaped by the interaction of supply gaps, energy exposure, brine regulation, digital efficiency, and infrastructure timing.
This OFW Intelligence scenario report helps decision-makers compare baseline expansion, accelerated circular transformation, and high-stress nexus crisis pathways without relying on independent forecasting.
Target Audience
- Utility Executives & System Operators: Understand how SWRO expansion reshapes system architecture to combat rising demand deficits and structural infrastructure stress.
- Regulators & Policymakers: Examine how CEN Workshop Agreement CWA 18153 helps establish standardized compliance paths to resolve current baseline brine disposal challenges.
- Infrastructure Investors & Financiers: Assess how addressing the capital inefficiencies of legacy assets can recover EUR 34.5 billion through targeted energy-recovery retrofits.
Report Deliverables
- Scenario Pathways: Provides analysis of baseline continuation, accelerated transformation, and high-stress desalination futures.
- Nexus Exposure: Delivers insight into water-energy dependencies, grid vulnerabilities, and Scope 2 emissions exposure.
- Investment Readiness: Enables evaluation of legacy retrofit opportunities, PPP models, and bankable infrastructure pathways designed to overcome fiscal barriers.
- Regulatory Transition: Provides assessment of early-stage brine valorization standards, mineral ownership frameworks, and developing circular economy regulation.

The Five Strategic Pillars
-
Architectures: Current expansion path
Examines how established procurement roadmaps and continued SWRO expansion attempt to address the baseline challenges of widening regional supply gaps.
-
Enablement: Accelerated circular transformation
Maps out the pathways required to shift plants toward circular models, addressing systemic disposal issues through brine valorization, renewable power, and resource recovery.
-
Resolution: High-stress nexus crisis
Assesses severe compounding failure modes where regulatory policy lag, prolonged drought, power grid constraints, and delayed infrastructure investments result in concurrent water and energy deficits.
-
Alignment: Efficiency and digital operations
Highlights critical near-term operational remedies—such as digital twins, smart metering, energy recovery devices, minimum efficiency standards, and NRW reduction—to curb severe systemic waste.
-
Capability Building: Investment and regulatory readiness
Links PPP and IWP models, pioneering circular economy frameworks, green finance, and performance metrics directly to the challenge of building bankable, risk-mitigated desalination assets.
Operational Excellence & Resilience
Scenario Report: Desalination Futures assesses a global water system currently constrained by widening supply-demand imbalances and intensifying water-energy exposure. Severe vulnerabilities, highlighted by US$ 39 billion in annual NRW leakage losses and widespread inefficient legacy infrastructure, serve as the driving catalyst for exploring advanced resilience measures. The report evaluates how utilities can counteract these baseline vulnerabilities through SWRO expansion, digital twins, smart metering, energy recovery devices, and renewable energy PPAs. Regulatory frameworks, such as Minimum Efficiency Performance Standards and CEN Workshop Agreement CWA 18153, are framed as essential tools to overcome historical inefficiencies and hit the target 2.0 kWh/m³ efficiency potential required for meaningful cost and emissions reduction.
Projected savings attainable by retrofitting legacy desalination infrastructure currently lacking energy recovery devices, while addressing 111 million tons of CO2 emissions exposure.

Expert Briefing: FAQs
The report provides a precautionary framework for comparing baseline continuation, accelerated circular transformation, and high-stress nexus crisis pathways. The development of this framework is directly driven by the projected 40% gap between demand and sustainable supply by 2030, helping stakeholders navigate infrastructure, energy, regulation, and investment uncertainties.
The nexus dominates because current water systems face severe systemic challenges: desalination relies heavily on stable power grids, while thermal power generation often relies on water for cooling. This vulnerability is underscored by the fact that water-sector electricity use consumes 4% of global electricity, necessitating the report’s deep analysis of grid dependencies, renewable energy PPAs, and demand-side flexibility options.
Rather than treating brine purely as an environmental liability, the report explores its potential as an industrial feedstock for lithium, magnesium, and potassium. This exploration is driven by the reality that 21% of global desalination plants remain inefficient, legacy assets, highlighting a clear need for circular economy regulations and standardized frameworks like CEN Workshop Agreement CWA 18153.
The report prioritizes foundational efficiency upgrades, digital twins, smart metering, and circular regulation. These urgent interventions are directly necessitated by the severe US$ 39 billion lost annually to NRW leakage, offering a structured approach for utilities looking to deploy Independent Water Plant models and Minimum Efficiency Performance Standards to halt systemic resource loss.
