Marine Water Desalination Market Report 2026

The marine water desalination market size has grown rapidly in recent years. It will grow from $12.03 billion in 2025 to $13.73 billion in 2026 at a compound annual growth rate (CAGR) of 14.2%. The growth in the historic period can be attributed to deployment of ro systems on navy and merchant ships, growth of msf and med technologies in marine applications, increasing freshwater demand in maritime operations, early adoption of ed systems on small tonnage vessels, advancements in thermal desalination efficiency.

The marine water desalination market size is expected to see rapid growth in the next few years. It will grow to $23.57 billion in 2030 at a compound annual growth rate (CAGR) of 14.5%. The growth in the forecast period can be attributed to integration of iot-based monitoring for marine desalination, rising use of solar-powered desalination systems, increasing deployment of desalination on passenger and yacht vessels, growth in energy-efficient large tonnage systems, adoption of advanced water treatment technologies in navy operations. Major trends in the forecast period include increasing adoption of reverse osmosis (ro) systems, growth in multi-stage flash (msf) and multi-effect distillation (med) systems, rising deployment of electrodialysis (ed) systems, integration of solar-powered desalination technologies, expansion of small and large tonnage desalination systems on vessels.

The rising demand for freshwater is expected to drive the growth of the marine water desalination market. Meeting this demand requires sustainable water management practices, conservation efforts, and collaborative strategies to ensure equitable access. Marine water desalination addresses freshwater scarcity by converting seawater or brackish water into potable water through processes such as reverse osmosis or distillation, providing a reliable source of clean water for various applications. For example, in March 2023, the World Economic Forum (WEF), a Switzerland-based non-governmental organization, reported that by 2030, global freshwater demand is projected to exceed supply by 40%. Consequently, the increasing need for freshwater is fueling the expansion of the marine water desalination market.

Leading companies in the marine water desalination market are focusing on developing innovative technologies, such as desalination systems that can produce freshwater from seawater at a lower cost than tap water. Desalination involves the removal of salt and minerals from saline water, making it suitable for human consumption or irrigation. In September 2023, engineers at the Massachusetts Institute of Technology (MIT) Corporation launched a solar-powered desalination device. This passive solar-powered system utilizes multiple layers of flat solar evaporators and condensers lined up in a vertical array and topped with transparent aerogel insulation. The system employs natural convection to drive the desalination process, preventing salt accumulation and enabling high-performance and reliable operation, even under extreme conditions. These innovations have the potential to address water scarcity in developing countries and offer a sustainable and cost-effective solution for freshwater production.

In October 2023, BW Group Limited, a US-based shipping company specializing in floating gas infrastructure, deep-water oil, and gas production, successfully acquired Safbon Water Technology Inc. for an undisclosed amount. The acquisition is aimed at strengthening BW Water's position in the water and wastewater treatment industry, particularly in the Americas. This strategic move will open new markets with desalination competencies in Asia and integrate Safbon Water Technology under the BW Water brand. Safbon Water Technology Inc. is a US-based company specializing in designing and supplying seawater reverse osmosis (SWRO) systems, brackish reverse osmosis (BWRO) systems, and nanofiltration (NF) systems for desalination applications.
