Water supply options for small island Groundwater from freshwater lenses limited quantity and risk of unsustainable extraction
rates and saltwater infiltration Rainwater collection and storage requires large surface areas and has a risk of siltation Tanker ships expensive and increases reliance on larger island or the mainland Desalination ships high investment cost and high operational costs On-site desalination high operational costs due to fuel costs, reliance on larger island or
mainland for fuel supply
Renewable Energy Desalination can be a practical solution
Water Supply for Small Islands: unique features and limited options
p3
Limited surface area for water collection or retention possibilities
Sensitive to natural disasters (cyclones, erosion, climate change)
Supply demand mismatches (dry or tourist seasons)
Limited natural freshwater resources (lenses, lakes)
Isolation from larger inhabited areas
Pollution (sanitation facilities, pesticides, leachate, fertilizers)
Small islands have unique features that affect the water supply
Benefits of Renewable Energy Powered Desalination
p4
Security of Supply: increases independence
Economic Development: facilitates the growth and deployment of economic activities
Fuel costs: reducing the cost burden of a clean and reliable water supply
Reduced imports: reduces the need for fuel or water imports

A: Renewable Energy Desalination can address a supply/demand mismatch
B: Renewable Desalination reduces fuel costs and imports
Can provide power and water Off-grid or mini-grid operation Optional back-up by energy storage or conventional diesel generator for 24h availability
The desalination process: reverse osmosis (RO) Proven technology Adopted worldwide by utilities and industry for seawater and brackish water desalination Ongoing development and demonstration of systems for grid-independent operation

System integration and advanced control systems provide enhancements
Address seasonal demand changes with ‘PV modules’ or ‘RO trains’ capable of long-term
shut-off during low-demand seasons
Include water storage as a low-cost buffer to match water supply and demand
Enables water supply when renewable energy is unavailable
Enables diversion of renewable power to the (mini) grid without disrupting water supply
(demand response)
Electricity storage or diesel generator to ensure continued operation when renewable energy
source is not available.
System Integration Design offers enhancements
p6
A: Design Challenges
Discontinuous operation customized design needed
Water demand mismatch (seasonal peaks – tourism) Direct coupling with RE
Large space required for renewable energy supply system (solar PV modules)
Energy recovery for small-scale systems
Limited operational experience
B: Logistic Challenges
Availability of chemicals (pre-treatment, anti-scalant, post-treatment)
Water quality monitoring (off-site laboratory in Small Island)
C: Possibly limited availability of experienced and trained O&M personnel
Capacity building required
Typical Challenges for Renewable Desalination Plants on Small Islands

Off-grid PV powered RO seawater desalination located in the Caribbean Assumptions:
Specified daily water production (m3/d) occurs during day-time only (no energy storage or diesel back-up)Costs for water storage excluded from this estimation
Masdar’s Renewable Energy Seawater Desalination Program
• The demonstration includes pilot plants located in Abu Dhabi. Each pilot plant will be operatedover 18 months.
• The plants will showcase different advanced and innovative desalination technologies: 4plants are currently under construction / commissioning
• The main objective is to demonstrate highly energy efficient desalination processes allowingfuture desalination plants to be cost-effectively powered by renewable energy sources.
• Ongoing discussions with Mascara NT to test a fully off-grid PV powered desalination pilotplant
