Desalination Capacity Will Increase By 50%

Will Desalination Capacity Increase By 50% By 2035?

Water has become one of the most critical geopolitical and economic issues of the 21st century. Increasing populations, accelerated urbanization, and drought cycles triggered by climate change are depleting freshwater resources, particularly in arid and semi-arid regions. In this context, desalination plants - facilities that convert seawater into potable and usable water - are emerging as a strategic infrastructure investment. The projected minimum increase of at least 50% in global installed desalination capacity by 2035 is being viewed not as an obligation for countries facing water stress, but rather as a survival strategy.

Which Regions Are Leading The Way In The Global Desalination Market?

Currently, the Middle East and North Africa region dominates the global desalination market. Countries such as Saudi Arabia, the United Arab Emirates, and Israel are continuously upgrading their capacities with efficiency gains in reverse osmosis technology. According to Global Water Intelligence data, the installed capacity, which currently stands at approximately 100 million cubic meters per day worldwide, is rapidly expanding due to large-scale projects, particularly in coastal cities of China and India. Water scarcity is no longer solely a problem for arid countries; climate models predict permanent shifts in rainfall regimes across regions including the Mediterranean basin, Southwest United States, and certain areas of Australia. This is driving desalination investments into new geographies.

What Obstacles Stand In The Way Of Desalination Growth?

The biggest obstacle to this growth is high energy consumption. Traditional thermal desalination methods rely on fossil fuels, while even modern reverse osmosis plants require 3 to 4 kilowatt-hours of energy per cubic meter. This conflicts with commitments to reduce carbon emissions and exacerbates environmental sustainability concerns. Furthermore, the discharge of saline water can harm marine ecosystems, and high installation costs represent a financial barrier for developing countries. However, integration of renewable energy sources and advancements in membrane technologies hold the potential to lower these costs.

Why Is The Forecast Probability High?

The forecast’s probability of realization is high because water scarcity is no longer solely a problem for arid countries. Increasing food demand is also directing agricultural irrigation towards desalination. Specifically, rapid urbanization in Africa and Asia is making access to clean water critical. Organizations such as the International Desalination Association (IDA) and Global Water Intelligence provide data that can validate capacity increases. While energy costs and environmental concerns may limit growth, it is anticipated that these barriers will be overcome as water security becomes a higher priority.

Frequently Asked Questions

Why Is Desalination Capacity Increasing?

Water scarcity, climate change, and population growth are depleting freshwater resources, particularly in arid regions. Desalination provides an alternative source by converting seawater into potable water. Increased investments in the Middle East, Africa, and Asia are accelerating capacity growth.

What Are The Environmental Impacts Of Desalination?

High energy consumption and saline water discharge are the primary environmental concerns. Fossil fuel use increases carbon emissions, while saline water can harm marine ecosystems. However, integration of renewable energy sources and advanced membrane technologies mitigate these effects.

How Can The Capacity Increase In 2035 Be Verified?

Global installed desalination capacity can be tracked through reports published by organizations such as the International Desalination Association (IDA) and Global Water Intelligence (GWI). The percentage increase can be verified by comparing it with data from the base year.
