    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

    4

    Data and image source: SWCC

    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 worlds 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

    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 countrys 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
