For more than half a century, the Gulf Cooperation Council (GCC) has treated seawater as a lifeline. Today, it is turning it into an economic asset. The GCC countries now account for an estimated 50–60% of the world’s total desalination capacity and produce approximately 40 per cent of all desalinated water globally, underscoring their position as the undisputed centre of the global desalination industry.
Desalinated water is not just supplementary in the region, it forms the backbone of national supply systems, providing 90% of Kuwait’s potable water, 86 per cent of Oman’s, and around 70% of Saudi Arabia’s. Saudi Arabia, home to megaprojects such as the Ras Al-Khair complex, is the world’s largest producer of desalinated water by volume, while the UAE holds the largest installed desalination capacity in the Arabian Gulf. To meet rising demand and enhance long-term resilience, the GCC has committed $100 billion in new investment to expand desalination capacity by 37% over the next five years, marking one of the most ambitious water-security programmes underway anywhere in the world.

The Gulf as a Desalination Superpower
Water scarcity is structural in the Gulf: low rainfall, high evaporation, fast-growing populations, and water-intensive economic development. Natural renewable freshwater per capita is among the lowest in the world, making desalination and reuse central to economic planning.
Over decades, GCC states have steadily built a dense network of plants. The World Bank notes that nearly 44% of global desalination capacity was already in the GCC by 2019, out of more than 18,000 plants worldwide producing about 87 million cubic metres of water per day. More recent regional estimates suggest the GCC now holds roughly half to 60% of global desalination capacity, and produces around 40% of desalinated water.
That build-out is accelerating. GCC countries have earmarked about $100 billion to expand desalination capacity over a five-year period, with plans to increase output by roughly 37%. This is not just about more plants; it is about more efficient plants. The older, energy-hungry thermal systems are being gradually replaced or complemented by reverse-osmosis technologies, which are more energy efficient, easier to pair with renewables, and quicker to deploy.
For investors and operators, the Gulf is effectively the world’s largest “desalination laboratory”. Scale gives local utilities and developers an advantage in:
Cost curves: Experience and volume help drive down unit costs of production and distribution.
Technology integration: The GCC is an early adopter of hybrid plants, smart grids, and AI-optimised networks that link power and water planning.
Export potential: Gulf-based players such as ACWA Power and regional engineering firms are increasingly competitive in bidding for desal projects in other water-stressed markets, from North Africa to Asia.
In effect, the Gulf is turning its historic water deficit into a platform business: mastering desalination and water management at home, then monetising that expertise abroad.
Building a Gulf Blue Economy
Globally, the “blue economy” is defined as the sustainable use of ocean resources for economic growth, jobs, and improved livelihoods while preserving ocean health. For the Gulf, this concept is being woven into national visions and mega-projects.
Saudi Arabia is the most explicit. Under Vision 2030, more than $3.2 trillion is expected to be injected into the kingdom’s economy by 2030, with a portion directed toward coastal and marine assets — from ports and logistics to tourism and offshore renewables. Within this, a “new blue economy” agenda aims to upgrade traditional activities such as shipping, fishing, and leisure through advanced technologies and data-driven management of Red Sea ecosystems.
Neom’s Oxagon, the planned floating industrial city on the Red Sea, is one of the clearest symbols. Marketed as a next-generation industrial and logistics hub, Oxagon is designed around clean energy, automation, circular manufacturing, and a dedicated “blue economy” zone of around 10skm blending sustainable blue innovation, water-based living, and marine research.
Across the GCC, similar patterns are emerging:
Ports and logistics: Major hubs such as Jebel Ali, Khalifa Port, and King Abdulaziz Port are expanding not only freight capacity but also value-added services (ship repair, bunkering, logistics zones) that anchor blue-economy clusters.
Tourism and coastal real estate: Projects along the Red Sea, Arabian Gulf and Gulf of Oman — integrating marinas, resorts, mangrove parks, and coral restoration are positioning sustainable waterfronts as premium real estate and tourism assets.
Marine innovation ecosystems: Start-ups and research labs are emerging around desalination, brine mining, marine biotechnology, and aquaculture, particularly in Saudi Arabia’s Red Sea corridor. The strategic question for GCC policy-makers is how to ensure this blue growth does not replicate the externalities of earlier industrialisation waves, especially given the sensitivity of semi-enclosed seas like the Arabian Gulf and Red Sea.
From Prize-Led Desal Breakthroughs to Digital Water
The Gulf’s water transition is no longer limited to building more plants; it is about systemic innovation.
In 2024, the UAE launched the Mohamed bin Zayed Water Initiative and partnered with the XPRIZE Foundation on a $119 million, five-year XPRIZE Water Scarcity competition to find breakthrough desalination technologies that are radically more sustainable, affordable, and scalable. The competition framework is explicitly global, but the UAE’s own dependence on desalination makes it a natural early adopter of any successful solutions.
At the policy level, the UAE Water Security Strategy 2036 sets targets to ensure sustainable access to water in normal and emergency conditions, while reducing overall demand, expanding reuse, increasing storage capacity, and cutting the carbon intensity of water production. Complementary initiatives aim to reduce water demand by about 21% and lift reuse of treated wastewater to around 95% by 2036.
Delivering those targets requires more than hardware. The UAE is upgrading national water supply networks with new pipelines, reservoirs, and treatment plants, and beginning to deploy AI and advanced analytics to optimise flows, reduce leakages, and match supply with real-time demand.
On the energy side, the Gulf is also moving gradually toward lower-carbon desalination. The UAE has explicitly identified “decarbonised desalination” as a key pillar of its Net Zero 2050 strategy, signalling a shift toward renewable-powered plants and more efficient processes. Similar language appears in Saudi sustainability frameworks, where blue economy investments are linked to clean energy and nature-positive coastal development.
For investors, three innovation themes stand out:
1. Low-carbon desalination: Renewable-powered reverse osmosis, energy-recovery devices, and modular plants for coastal communities.
2. Water reuse and circularity: Advanced treatment and recycling infrastructure for cities, industry, and agriculture, backed by performance-based PPPs.
3. Digital water & AI: Platforms that integrate SCADA data, demand forecasting, and predictive maintenance to cut losses and energy use across integrated water-energy systems.
Managing the Risks: Marine Ecosystems, Brine, and Regulation
The expansion of desalination and coastal infrastructure is not without risk. Desalination remains energy-intensive and generates large volumes of hypersaline brine that, if poorly managed, can harm marine ecosystems. For semi-enclosed bodies of water such as the Arabian Gulf, where natural flushing is limited, cumulative impacts can be significant.
Regional policymakers are beginning to respond. GCC officials have emphasised “significant and continuous efforts” to protect seas and oceans, aligning with the UN Sustainable Development Goal on life below water.
The UAE has expanded protected areas, with total protected territory increasing to more than 15 per cent of national land and sea area in recent years. Other Gulf states are developing similar marine protected areas, coral restoration projects, and mangrove planting programmes.
In parallel, there is growing interest in:
• Brine valorisation: Recovering minerals and industrial salts from brine streams, turning a waste liability into a revenue stream and reducing ecological impact.
• Stricter standards and monitoring: Tightening discharge guidelines, mandating environmental impact assessments, and using remote sensing to track changes in coastal water quality.
• Blended finance for conservation: Linking blue bonds, sustainability-linked loans, and climate funds to measurable outcomes in water efficiency and marine protection.
These safeguards are not optional. Without them, the Gulf’s blue economy could face reputational, regulatory, and physical constraints that threaten long-term value creation.
What Comes Next: From Regional Necessity to Exportable Expertise
As climate stress intensifies, more countries are turning to seawater—Jordan’s multi-billion dollar Aqaba–Amman desalination project and Morocco’s plan to source 60 per cent of its drinking water from desalination by 2030 are just two recent examples. The GCC’s decades of experience, combined with its current investment wave, place it in a strong position to supply technology, capital, and operating know-how to this global market.
To fully unlock that advantage, three strategic priorities stand out for Gulf governments and businesses:
1. Treat water as a strategic sector, not a utility cost line
That means embedding water into industrial policy, export strategies, and climate diplomacy, positioning Gulf firms as partners of choice for water-stressed economies from North Africa to South Asia.
2. Tie blue-economy growth to hard sustainability metrics
Clear targets for carbon intensity of desalination, brine management, marine biodiversity, and reuse rates will be essential to avoid backlash and maintain access to green and blue finance.
3. Build innovation ecosystems, not isolated projects
Prize mechanisms like the UAE-backed XPRIZE Water Scarcity, open testbeds in projects like NEOM’s Oxagon, and cross-border research alliances can make the Gulf a global hub for water and ocean innovation, not just a large customer.
The Gulf’s relationship with water has always been about survival. The emerging blue economy makes it about strategy: redefining how arid coastal nations can grow, diversify, and lead in a world where “blue gold” may matter as much as the black kind.
