Saudi Arabia and the United Arab Emirates are at the forefront of new desalination technology powered by renewable energy
- Oct 03, 2022, 2:00 PM CDTMENA and Asia-Pacific regions dominate the current desalination market.New technologies could commodify wastewater produced by desalination.Long seen as a high-cost, energy-intensive process, desalination mega-projects are seeking to tap renewable resources to limit the cost and environmental concerns of this crucial technology.
The companies have already installed a pilot plant at the Jebel Ali power plant and desalination complex, which produces 1000 litres per day, and project the new technology could push the cost of desalinated water as low as $0.02 per litre. Although desalination costs vary considerably based on water source, technology and electricity prices, the average range globally is between $0.50 and $1.50 per cu metre.
Desalination is already a widespread practice, with approximately 16,000 plants operating in 177 countries. As of 2016 the Middle East and North Africa region accounted for 46.7% of the world’s desalination capacity, followed by the Asia-Pacific region and North America . The government is targeting an installed desalination capacity of 6.4m cu metres per day by 2050, up from 800,000 in 2021.
While most desalination plants in the MENA region are powered by fossil fuels, the increasing use of renewable energy – coupled withKarmSolar, an Egyptian solar power and utilities company, is constructing a pilot solar-powered desalination plant at Marsa Shagra on the Red Sea coast with a capacity of 200 cu metre per day. According to the company, any unstored excess water supply produced during peak sunlight hours could be used for local construction activities or in hydroponic gardens.
