The marine water desalination market size is expected to see rapid growth in the next few years. It will grow to $21.03 billion in 2029 at a compound annual growth rate (CAGR) of 14.5%. The growth in the forecast period can be attributed to increased demand for fresh water, increasing water demand in water-stressed regions, the integration of desalination plants with other water treatment processes, growing global population leading to increased demand for freshwater, increasing investments in desalination infrastructure by governments and private sectors. Major trends in the forecast period include technological advancements, advanced membrane technologies, rising focus on decentralized desalination systems, innovations in water storage and distribution infrastructure, new product innovation.

The marine water desalination market is poised for growth, driven by the increasing demand for fresh water. Addressing fresh water scarcity requires sustainable water management practices, conservation efforts, and collaborative initiatives to ensure equitable access. Marine water desalination plays a crucial role in mitigating fresh water scarcity by converting seawater or brackish water into potable water through processes such as reverse osmosis or distillation. This provides a reliable source of clean water for various uses. According to a report by the Parks and Recreation business in September 2023, global annual freshwater usage exceeds 4 trillion cubic meters, with consumption surpassing 2,002 trillion cubic meters as of 2022. Water demand is projected to rise by 20 to 30 percent by 2050. Consequently, the increased demand for fresh water is a key driver behind the growth 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.
