Global Market Size, Forecast, and Trend Highlights Over 2024-2036

Solar Water Desalination Plant Market size is poised to reach USD 7 Billion by the end of 2036, growing at a CAGR of 8% during the forecast period, i.e., 2024-2036. In the year 2023, the industry size of solar water desalination plant was USD 3 Billion. The reason behind the growth is impelled by the growing shortage of water across the world. In many regions of the world, arid climates, rapid population growth, and urbanization have resulted in water scarcity.

 For instance, more than 1 billion people will reside in regions with limited water supplies by 2025. Particularly, by 2050, there will be around 3 billion people living in metropolitan areas worldwide who will be affected by water scarcity, double from over 900 million in 2016.

The increasing research in desalination technology is believed to fuel the solar water desalination plant market growth. For instance, a group of Chinese and MIT researchers has found a solution known as a passive solar evaporation system to the issue of salt buildup without requiring any power source other than sunlight, the procedure might also be utilized to remediate contaminated wastewater.

Solar Water Desalination Plant Market: Growth Drivers and Challenges

Growth Drivers

  • Rising Environmental Pollution - Desalination plants which are powered by renewable energy can lessen the strain on rivers, lakes, and groundwater as sources of freshwater to lessen its negative effects on the environment. Many desalination plants are located in sunny regions where solar energy might offer a more environmentally friendly energy source and help them deal with concerns of sustainability.
  • Growing Adoption of Green Energy- Desalination can benefit greatly from the use of renewable energy since it is mostly powered by sources such as solar, wind, wave, geothermal, and blue energy which aids in reducing the need for fossil fuels and contributes to a safer future. According to estimates, future predictions for renewable energy indicate that global solar capacity will increase by over 550 gigawatts (GW) by 2024.
  • Increasing Agriculture Industry- Solar desalination, converts saltwater into freshwater that may be used for irrigation or mineralized for drinking, thus promoting sustainable agriculture. For instance, globally, the agriculture industry is expected to expand by over 5% between 2024 and 2028, reaching a market size of around USD 4 trillion by that year.


  • Side Effects of Desalination on Environment - Waste and hazardous chemicals that are bad for the environment are produced by desalination plants which has the potential to worsen climate change, increase reliance on fossil fuels, and raise greenhouse gas emissions. It is a costly, and energy-intensive process that can have a detrimental effect on how land is used in communities, increase erosion, disrupt the surrounding environment both visually and aurally, and release pollutants into the atmosphere and water. The procedure can produce pollutants, which may be harmful to the marine environment as a result of which mature fish, larvae, or other marine life get sucked into open water surface intake pipes, leading to serious injuries or even death. The main drawbacks of desalination are the creation of brine owing to its dangerously high concentration of salts and other minerals, and brine trash, which is frequently disposed of in the ocean, poses a risk to marine life by suffocating bottom-dwelling organisms and drastically changing coastal ecosystems. Moreover, apart from brine, the desalination process's high energy consumption also has a lot of detrimental environmental repercussions, such as an excessive amount of CO2 emissions.
  • Slow adoption of solar water desalination plants owing to high Infrastructure Cost
  • Lack or unavailability of sunlight especially during night hours and non-sunny weather

Solar Water Desalination Plant Industry - Regional Synopsis

APAC Market Forecast

The solar water desalination plant market in Asia Pacific is predicted to account for the largest share of 42% by 2036 impelled by rapid urbanization. For instance, In India, more than 451 million people live in urban areas, and this figure is increasing annually by around 2%. Particularly, by 2030, it is projected that over 350 million Indians will reside in cities. As a result, water supplies in many parts of the region are being stressed, which may drive the solar water desalination plant market growth. According to sources, a serious water risk will exist for more than 25 Indian cities by 2050.

In addition, the increase in government initiatives to provide affordable and safe drinking water is further expected to fuel market growth. In May 2023, the Indian Institute of Technology (IIT) announced a partnership with Israel to construct an "India-Israel Center of Water Technology" (CoWT) in Water Resources and use contemporary desalination facilities to meet India's water needs for agriculture and consumption.

Middle East and Africa Market Statistics

The Middle East and Africa solar water desalination plant market is estimated to be the second largest, during the forecast timeframe led by the high dependence on the desalination of ocean water to fulfill the water demand. Saudi Arabia is the biggest consumer of desalinated water.
