CONTENTS
WHAT IS SUSTAINABLE DESALINATION?
Sustainable Desalination uses a group of technologies to maximize economic and environmental efficiencies within the entire process. Renewable energy supply is an obvious important part, but not the only contribution to Sustainable Desalination
3
• Solar & Wind energy supply
• Energy recovery devices
• Maximized water recovery
• High-performance membrane
• Zero discharge
• Subsurface intakes
• Materials design
• Smart Systems
• Automation
FRESH WATER AVAILABILITY WORLDWIDE

• There is an abundance of water, but it is not always accessible
• Saudi Arabia and the Gulf Region is one example in the world where this is the case
SAUDI DESALINATION MARKET
5
• Saudi Arabia is amongst the driest regions on earth
• It has one of the world’s fastest population growth rates and its population is expected to reach approximately 35 million by 2020*
• The pressure on water demand is great
• It is further complicated by the rapid increase in middle-class life styles that increase per capita water demand

SAUDI DESALINATION MARKET

• KSA depends heavily on Desalination
• Largest Desalination Market in the World
• Makes up the biggest share in the GCC

• The desalination infrastructure requires a huge amount of energy (over 3,500 T BTU)
• Approximately, 10% of domestic energy consumption is used to Desalinate water*
• This figure is growing, not shrinking. Energy requirements in desalination have been steadily increasing as shown in the graph

and Solar Energy Deployment Roadmap (KACARE, 2013)
ENERGY CONSUMPTION IS UNSUSTAINABLE
9
• As you know, KSA energy grid runs on oil
• It is projected that by 2038 domestic oil demand will outstrip supply
• By 2026 domestic oil demand will outstrip the export of oil
• If KSA domestic energy consumption, including the energy needs of desalination, continues at the current trajectory, it is highly unsustainable

The 3 E's of Sustainability
• In Saudi Arabia, it is critical to find sustainable ways to produce and to treat water
• The country’s population growth and economic growth cannot be supported otherwise
• This critical situation is repeated throughout the Gulf and Middle East, and can be found in other regions of the world
KSA INITIATIVE FOR DESALINATION POWERED BY
RENEWABLE ENERGY
• Saudi Arabia has taken steps in the right direction.
• In 2010, the Initiative for Desalination Powered by Renewable Energy was launched under the direction of King Abdulaziz City for Science and Technology (KACST)
• Solar powered desalination is an attractive option: Good solar resource in the Middle East
• Main Target: Reaching a value of 1.5 SAR per m3 (0.4 USD/m3) using solar powered desalination

Phase 1 – Al Khafji
SWRO 30.000 m3/d (increased to 60.000 m3/d) solar power desalination plant
Completion scheduled for mid 2017
Phase 2
300.000 m3/d solar power desalination plant (all technologies to be considered)
Starting after 1st phase
Phase 3
Implement several water desalination plants across the KSA
Starting after 2nd phase
Phase 4
Apply the knowhow and experience to provide low-cost water for agriculture

• In 2017-2018, KSA intends to begin installing an additional 2.6 MN m3/day and 3,000 MW at 8 different sites
• There is the opportunity that a percentage of this capacity be met at least in part by next-generation plants based on Sustainable Desalination
• Doing so would lay the foundation and secure the future of Sustainable Desalination
