Dubai will seek partners this year to build its first solar-powered desalination plant as the emirate tries to diversify away from burning fossil fuels to increase its water supply, the head of the Dubai Electricity and Water Authority (Dewa) said in an interview. The plant, using reverse osmosis technology, will have capacity to produce 120mn gallons a day of drinkable water by 2024, CEO Saeed Mohammed Al Tayer said in Dubai. Dewa is also developing a reservoir to hold as much as 6bn gallons of water reserves, and the utility currently stores about 700mn gallons, Al Tayer said at the World Government Summit in Dubai.
