- Abstract:
- Water desalination is gradually emerging as the leading solution to cope with increasing water stress: i.e., the imbalance between water demand and quantities available. The United Nations estimates that by 2025, two-thirds of the world’s population will be affected by such challenges. The causes of water scarcity are multiple, including climate change, intensive agriculture, and population growth. This requires states to rethink their water policies, which are central to preserving their stability, resilience and sovereignty. A real “boom” in desalination industries is at work. The majority of Gulf countries now largely depend on desalinated water for their inhabitants’ consumption: in the United Arab Emirates (UAE), 42% of drinking water comes from desalination plants producing more than 7 million cubic meters (m3) per day, in Kuwait it is 90%, in Oman 86%, and in Saudi Arabia 70%. In 2022, there were more than 21,000 seawater desalination plants in operation worldwide, almost twice as many as a decade ago, and the sector’s capacity is growing at between +6% and +12% per year. By 2030, desalination capacity in Middle Eastern countries is expected to almost double, as part of plans announced in the region to prepare these economies for their transition to “post-oil” and to foster resilience. Saudi Arabia’s desalination capacity is set to increase from 5.6 million cubic meter (m3) per day in 2022 to 8.5 million m3 per day in 2025, and it will have to cover more than 90% of the country’s water consumption. The same holds for the UAE, Kuwait, Bahrain and Israel, where the production of desalinated water will more than double by 2030. With the rise of available solutions to meet all such needs, these technologies are now in demand on virtually every continent, while the Middle East today represents only 50% of installed capacity worldwide. In Africa, large-scale projects have recently been announced in Algeria and Morocco, countries that until now have had sufficient resources. Other countries such as Ghana, Senegal and Kenya supply many cities with desalinated seawater. This is also the case for Cairo. In the Indo-pacific region, particularly in China and India, the needs for desalinated water are increasing, driven by growing industries and decreasing available water. In 2020 alone, the construction of more than 35 desalination plants was announced in China, as well as six in the Philippines, and six in Taiwan. In the Americas, the west coast of the United States stands out with important projects in California, and Texas is not far behind. In Latin America, new projects are emerging in Peru and Chile, driven mainly by the needs of the mining industry, while in Mexico the demand for desalinated water notably comes from the population. Finally, island areas stand out for their strong needs for desalinated water: Cebu in the Philippines, Cape Verde, the Canary Islands and the Maldives are increasingly using desalination capabilities. European firms still lead, but Asian or local players are taking off There are many industrial players of varied size, although some have emerged for more than ten years as undisputed market leaders: in France, they include Engie and Veolia, whose merger with Suez opened up new prospects in the Americas, the Middle East and Europe; but there is also IDE Technologies, the Israeli champion of desalination; Korea’s Doosan Heavy, China’s Abengoa, and Spain’s Acciona. More recently, companies in emerging countries have distinguished themselves by obtaining large-scale contracts. This is particularly the case of Gulf players like the Emirati company Metito and the Saudi firm Advanced Water Technologies. Egypt also has industrial actors. Overall, the technology of reverse osmosis is largely mastered, while production differentiation concerns capacity, operational costs, electricity consumption and plant life.
