Desalination Project Viability, $1.2 B Corpus Christi Reversal, 1 Kiewit Termination, and a Permit Delay (2025-2026)

The necessity of desalination as a solution to global water scarcity is now colliding with the economic and infrastructural realities of its immense energy demand. After a period of aggressive capacity expansion, the desalination market is entering a phase of heightened project risk, where sticker shock, regulatory friction, and grid-impact concerns are causing significant delays and cancellations. The cycle of planning, terminating, and then being forced to reconsider high-cost projects, as exemplified by Corpus Christi, Texas, signals a critical inflection point where project viability is no longer guaranteed by water scarcity alone; it is now dictated by the ability to solve the attendant energy challenge.

Desalination Project Risks, Commercial Scale Stalls Despite Growing Water Demand

The momentum for large-scale desalination projects is now hitting a wall of economic and energy reality, forcing municipalities and industries into a recurring cycle of planning, cancellation, and forced reconsideration under the duress of dwindling water supplies.

• The most pointed example of this trend occurred between 2025 and 2026 in Corpus Christi, Texas. The city canceled a contract for a major desalination plant with contractor Kiewit in September 2025, citing the unexpected $1.2 billion cost. However, by June 2026, facing the prospect of emergency water restrictions, the city was forced to reconsider the high-cost project, highlighting a pattern of necessity overriding prior financial objections.
• This dynamic contrasts with the 2021-2024 period, which was characterized by a focus on sheer capacity expansion, particularly in the Middle East. Mega-projects like the Taweelah plant in the UAE and the Ras Al Khair plant in Saudi Arabia set global scale records, with the primary focus on securing water supply through proven Public-Private Partnership (PPP) models.
• This friction is not confined to the United States. In Chile, the Collahuasi copper mine’s critical desalination plant project had its environmental permit ruling pushed to 2026. This exemplifies how regulatory hurdles tied to environmental and energy impacts can stall essential industrial infrastructure that is dependent on desalinated water.
• Adding another layer of risk, the 2025-2026 timeframe saw a heightened focus on the geopolitical vulnerability of these facilities. Analyses from this period highlighted how desalination plants in the Gulf region could become strategic military objectives during a conflict, turning civilian infrastructure into a liability and adding a significant security risk premium for investors and contractors.

Project Cancellations, $6 B NEOM Contracts and 1 Corpus Christi Reversal

High capital intensity and shifting strategic priorities are leading to significant project delays and outright cancellations, even within the most ambitious development programs, signaling that financial and political realities are beginning to temper the pace of desalination deployment.

• In September 2025, the Corpus Christi City Council terminated its agreement with Kiewit for a planned desalination plant due to sticker shock over its $1.2 billion estimated cost and financing concerns. This reversal demonstrates the acute financial pressure municipalities face when confronted with the true capital cost of securing a climate-independent water source.
• The risk of delay is also prominent in industrial projects. In Chile, a ruling on the environmental permit for the Collahuasi copper mine’s desalination plant was deferred to 2026, threatening the operational timeline for a major mining operation that relies on this future water supply.
• Even the most well-funded and strategically important giga-projects are not immune. In March 2026, it was reported that contracts worth $6 billion associated with NEOM’s Trojena ski resort project in Saudi Arabia were canceled as part of a broader project reprioritization, underscoring that even national-level initiatives are subject to capital discipline and revision.

Middle East vs. US, Regional Desalination Growth Faces Divergent Headwinds

While the Middle East remains the global epicenter for large-scale desalination capacity driven by national strategic imperatives, project execution challenges emerging in developed nations like the United States reveal critical vulnerabilities in financing models and public acceptance that are absent in state-led economies.

• The Middle East, particularly the Gulf Cooperation Council (GCC) countries, continues to lead global capacity growth. Saudi Arabia plans to meet 90% of its domestic water demand with desalinated water by 2030, leveraging state-backed entities like the Saudi Water Partnership Company (SWPC) and developers like ACWA Power to execute mega-projects. During the 2021-2024 period, this state-driven model proved highly effective at attracting private capital and building infrastructure at scale.
• In contrast, the experience in the United States during 2025-2026 illustrates a different reality. The saga in Corpus Christi shows how local political opposition and sticker shock over project costs can halt development, even in regions facing acute water stress. This highlights a key difference where projects in the U.S. are more susceptible to local fiscal and political pressures.
• Other regions are following the Middle East’s expansionary model. Algeria, for instance, is set to increase its desalination capacity by 70%, treating it as a matter of national water security. This state-led approach allows for long-term planning that can override short-term cost objections.

SWRO Technology Maturity, Commercial Scale Dominance Creates Energy Burden

Seawater Reverse Osmosis (SWRO) is a fully mature and dominant technology, but its commercial success is predicated on an energy-intensive process that has become its greatest liability, creating a market-wide vulnerability that emerging, more efficient technologies are not yet ready to solve at scale.

• Throughout the 2021-2024 period, the industry standard for SWRO energy consumption hovered around 3.0-5.0 k Wh/m³. The focus was on incremental optimizations of this mature technology, such as improvements in energy recovery devices, rather than fundamental shifts.
• By 2025-2026, the energy burden became a central point of failure for projects. While best-in-class demonstration plants achieved consumption as low as 1.86 k Wh/m³, the vast majority of commercial-scale operations still consume far more. This high energy use, accounting for up to 75% of operating costs in some regions, was a direct factor in the financial infeasibility of projects like the one initially proposed in Corpus Christi.
• Innovations are being pursued, as seen with Micron’s adoption of printed spacer technology for energy savings in 2025. However, more disruptive technologies like Forward Osmosis remain at a lower Technology Readiness Level (TRL 7) and are not yet cost-competitive with the entrenched, albeit inefficient, SWRO standard. This leaves the market dependent on a technology whose primary weakness is now its most significant risk factor.

SWOT Analysis, Desalination’s Strategic Imperative vs. Economic Hurdles

The strategic necessity of desalination as a climate-resilient water source is undisputed, but its significant operational weaknesses, particularly high energy costs and dependency on strained electrical grids, are manifesting as tangible threats that directly challenge project bankability and timelines.

2026 Desalination Outlook: Integrated Renewables as the Key De-Risking Factor

If new desalination projects continue to be proposed as standalone water factories reliant on the public grid, expect a continued pattern of project cancellations and delays as grid-impact assessments and energy cost volatility become insurmountable approval hurdles for regulators and financiers.

• Watch for municipalities and developers to begin mandating co-located solar or wind generation as a standard component of project proposals. This proactive step internalizes the energy cost and decouples water production from grid constraints, making projects more resilient and palatable to stakeholders.
• The bankability of large-scale projects, such as Jordan’s Aqaba–Amman National Water Carrier, which secured financing approval in January 2026, will increasingly hinge on their ability to present a clear, sustainable, and long-term energy procurement plan.
• The key financial metric will evolve from focusing solely on the Levelized Cost of Water (LCOW) to an integrated Levelized Cost of Water and Energy (LCOW+E). Projects that can offer cost certainty for both water and its energy input by bundling the desalination plant with a dedicated renewable power source will become far more attractive to long-term investors. A failure to make this shift will leave projects vulnerable to the exact pressures that stalled the Corpus Christi plant.
