“…Reverse osmosis is commonly used for desalination process world over. However, Saudi Arabia uses thermal multistage flash distillation process that is energy intensive and requires ~10 to 12 TWh to desalinate 1 m 3 sea water (Ghaffour et al 2014, Chandrasekharam et al 2015c). The quantity of electricity generated during the desalination process is shown in Fig.…”

“…Due to severe water scarcity, the government adopted a policy not to grow wheat from 2016. Thus wheat import is expected to reach 3.03 million tonnes in MY 2013-2014 compared to 1.92 million tonnes in -2013(USDA 2013, Chandrasekharam et al 2015a. Placing the country's food security with other countries is not a sensible decision.…”

The future economy of the Middle East countries (GDP growth) depends on the availability of fresh water for domestic and agricultural sectors. Saudi Arabia, for example, consumes 275 L/day per capita of water that is generated from desalination process using 134 x 10 6 kWh of electricity. With 6 % population growth rate, demand for fresh water from fossil fuel based desalination plants will grow at an alarming rate. It has been reported that Saudi Arabia's reliance on fossil fuels to generate electricity and generate fresh water through desalination using the same energy source is economically and politically unsustainable. This may lead to destabilisation of the global economy. However, Saudi Arabia has large geothermal resources along the Red Sea coast that can be developed to generate power and support the generation of fresh water through desalination. The cost of fresh water can be further lowered from the current US$ 0.03/m 3 . Among the gulf countries, Saudi Arabia can become the leader in controlling CO 2 emissions and mitigating the impact on climate change and agricultural production. This will enable the country to meet the growing demand of food and energy for the future population for several decades and to reduce food imports.

Scale production occurs during enhanced geothermal system (EGS) processes due to various conditions. The production of scales in pipes or fractured reservoir narrows the diameter of the injection and production well, decreasing permeability and reducing EGS efficiency. However, geothermal water flushing during EGS processes can be implemented to recover the permeability. In this study, an experimental instrument to simulate a geothermal system was applied to observe the chemical composition change of core and water samples. To simulate the EGS, an experiment was conducted by injecting the geothermal fluid in several cycles to the fractured core. Results showed that Si ions decreased in the geothermal fluid and permeability decreased due to precipitation. Thereafter, flushing was applied, and dissolution occurred inside the fracture, increasing the permeability.
