Global Desalination Market Analysis: Growth, Trends, and Forecast 2025-2033

Introduction

The global desalination market is poised for significant growth, expanding from US$ 17.64 billion in 2024 to approximately US$ 40.28 billion by 2033, with a compound annual growth rate (CAGR) of 9.61% between 2025 and 2033. This surge is primarily driven by the increasing global water scarcity and the growing demand for potable water. Desalination technologies, including reverse osmosis (RO), multi-effect distillation (MED), and multi-stage flash (MSF) distillation, are the backbone of this growth, offering solutions to water-scarce regions across the globe.

Market Drivers

1. Increasing Global Water Scarcity

One of the most significant drivers of the desalination market is the increasing water scarcity caused by factors such as population growth, climate change, and industrialization. Around 4 billion people—roughly two-thirds of the world’s population—experience water shortages for at least one month every year. By 2030, around 700 million people could be displaced due to extreme water shortages. The demand for fresh water is projected to increase significantly, especially in water-scarce regions such as the Middle East, North Africa, and parts of Asia-Pacific.

Desalination offers a viable solution to this crisis, converting seawater and brackish water into potable water. In nations such as Saudi Arabia, UAE, and Israel, desalination is already a critical component of their water supply strategy.

2. Technological Advancements in Desalination

The desalination industry has witnessed remarkable advancements in technology, especially in reverse osmosis (RO) and thermal desalination. These innovations have led to more energy-efficient and cost-effective desalination processes. The development of new membranes, energy recovery systems, and automation techniques have significantly reduced operating costs while improving overall efficiency.

For example, in December 2023, Hexagon AB’s green-tech initiative, R-evolution, launched a desalination program aimed at improving the scalability and efficiency of desalination plants worldwide through the use of digital twin solutions. These advancements are making desalination more viable for water-scarce regions and ensuring its sustainability.

3. Government Investments and Initiatives

Governments globally are heavily investing in desalination projects to ensure water security. Public-private partnerships, subsidies, and favorable policies are accelerating the construction of desalination plants. For instance, Saudi Arabia’s Crown Prince recently announced the creation of a Global Water Organization, which will invest over $6 billion in water projects worldwide. Similarly, the UAE continues to lead in desalination capacity, investing in cutting-edge technologies such as solar-powered desalination plants to reduce environmental impact.

4. Environmental Concerns and Sustainability

As the demand for desalination grows, so do the concerns regarding its environmental impact. Desalination processes are energy-intensive and produce brine, which, if not properly managed, can harm marine ecosystems. Despite these challenges, the industry is innovating, integrating renewable energy sources such as solar and wind power into desalination plants to minimize environmental footprints. Furthermore, advancements in energy recovery technologies are helping to make desalination more sustainable.
