What Fueled The Previous Growth In The Solar Water Desalination Plant Market?
The solar water desalination plant market has seen considerable growth due to a variety of factors.
• In recent years, the market size of the solar water desalination plant has seen significant growth. Expected to grow from $2.85 billion in 2024 to $3.1 billion in 2025, it will reflect a compound annual growth rate (CAGR) of 8.7%.
The historical growth of this market can be associated with several factors. These include the ever-expanding agriculture industry, the rising global water shortage and the subsequent demand for freshwater resources, increasing population and urbanization that have led to a surge in water consumption, a worldwide soaring demand for fresh water, and a heightened use of solar energy globally.
How Does the Forecast Look for the Solar Water Desalination Plant Market?
The solar water desalination plant market is expected to maintain its strong growth trajectory in upcoming years.
• The market size for solar water desalination plants is projected to experience substantial expansion in the coming years. The market is set to reach $4.1 billion by 2029 with a compound annual growth rate (CAGR) of 7.3%.
The predicted growth during the forecast period can be linked to the escalating need for fresh water and the toll of water scarcity, the rise in environmental sustainability awareness, and the push to decrease greenhouse gas emissions. Fluctuating energy sources and an increase in environmental pollution, coupled with the steady rise in green energy utilization, also contribute to this growth. Noteworthy trends projected within this period include technological progress, advancements in solar technology, the increasing use of smart technologies in solar water heaters, the merging of solar desalination with energy storage solutions to enable continuous operation, as well as ongoing research and development efforts to boost the efficiency and scalability of solar desalination.
What Are The Leading Drivers Of Growth In The Solar Water Desalination Plant Market?
The escalating problems of water scarcity and the growing need for freshwater are projected to drive the expansion of the solar water desalination plant market. Factors like population expansion, urban growth, climate variations, water contamination, inefficient utilization of water, economic progress, and insufficient infrastructure are causing increase in water scarcity and demand for freshwater. Solar water desalination systems offer a solution by employing renewable solar power to transform seawater into freshwater, ensuring a steady and sustainable water source in regions with limited access to freshwater supplies. As indicated by the United Nations, a U.S. intergovernmental organization, in March 2023 approximately 1 billion urban dwellers globally are currently facing water scarcity. This number is predicted to reach between 1.7 billion and 2.4 billion within the next 30 years, meaning by 2050. Consequently, escalating water scarcity and freshwater demand are the major driving forces behind the expansion of the solar water desalination plant market.

How Are Emerging Trends Reshaping The Dynamics Of The Solar Water Desalination Plant Market?
Dominant entities in the solar water desalination plant industry are leaning towards the invention of modern systems and technologies with increased water-production and salt-rejection rates in a bid to enhance their market earnings. Greater water-production rates are indicative of enhanced efficiency and productivity, while elevated salt-rejection rates mean reduced residual salt levels in the treated water. For instance, the US-based Massachusetts Institute of Technology (MIT) Corporation, a research university, unveiled a solar-powered desalination device in September 2023. This entirely solar-powered desalination system utilizes multiple layers of flat solar evaporators and condensers arranged vertically, topped with a transparent aerogel insulation. The system avoids salt-clogging issues and ensures reliability and high performance by inducing natural convection that drives the desalination process, preventing salt build-up, even under severe conditions. This innovation in solar desalination technology carries the potential to mitigate water shortage in underdeveloped nations and offer a cost-effective and sustainable alternative for freshwater production.
