On the desert shores of the Red Sea, Jordan plans to build a vast desalination plant to send drinking water hundreds of kilometres across its arid interior to the capital, Amman – bolstering climate resilience and reducing reliance on Israel for the vital resource.
As climate change exacerbates water scarcity in Jordan, a deterioration in the country’s already prickly ties with Israel since the start of the Gaza war has underscored the strategic importance of the roughly $6-billion desalination initiative, billed by its backers as a strategic climate adaptation project.
But despite receiving $295 million in support for the project from the UN’s Green Climate Fund (GCF), the energy-hungry plant – which will double the power needs of Jordan’s water sector – will get no more than 27% of its electricity from a purpose-built solar farm in the desert near the plant in Aqaba. The rest will come from the grid, whose power is mostly generated by fossil gas.

On the desert shores of the Red Sea, Jordan plans to build a vast desalination plant to send drinking water hundreds of kilometres across its arid interior to the capital, Amman – bolstering climate resilience and reducing reliance on Israel for the vital resource.
As climate change exacerbates water scarcity in Jordan, a deterioration in the country’s already prickly ties with Israel since the start of the Gaza war has underscored the strategic importance of the roughly $6-billion desalination initiative, billed by its backers as a strategic climate adaptation project.
But despite receiving $295 million in support for the project from the UN’s Green Climate Fund (GCF), the energy-hungry plant – which will double the power needs of Jordan’s water sector – will get no more than 27% of its electricity from a purpose-built solar farm in the desert near the plant in Aqaba. The rest will come from the grid, whose power is mostly generated by fossil gas.
To get salt out of sea water, it has to be pushed at high pressure through a membrane – a process requiring huge amounts of electricity.
The annual planet-heating emissions from producing the non-renewable power needed for the plant would be equivalent to having 160,000 petrol-run cars on the road for a year, according to an analysis by Climate Home News of figures provided by the project’s developers to the GCF – the world’s largest multilateral fund to help developing countries tackle climate change.
Such forecasts prompted a warning from its independent technical advisory panel and criticism by climate campaigners, but the GCF board nevertheless approved the financing at a meeting late last year, with GCF Executive Director Mafalda Duarte hailing it as a “milestone project”.
A GCF spokesperson told Climate Home News its design “required the balanced optimisation of multiple objectives”, among them water security, financing considerations and climate-related benefits.
Asked to respond to concerns about the project’s sustainability, a spokesperson for Jordan’s Ministry of Water and Irrigation said the plant is key to tackling the nation’s water deficit, in tandem with other steps to conserve supplies such as managing leaks.
“We have carried out environmental impact studies for the Aqaba desalination plant,” the spokesperson added. “All donor countries reviewed and approved these studies.”
Dry and getting drier
Jordan is already one of the world’s most water-stressed countries, and climate change impacts mean the country of about 11 million people is getting less rain at a time of population growth, in part due to the arrival of refugees from the war in Syria.
Half of Jordanian homes currently receive water for less than 24 hours a week and many pay to get tanker trucks to deliver extra water despite the high cost.
“Every Jordanian living in a village or city … can feel, especially in the summer, that the amount of water reaching their home is not enough,” said University of Jordan water science professor Elias Salameh.
At the same time, heightened political tensions in the region are raising fears over a long-standing water supply accord with Israel.
Prominent Israeli news outlet Ynet quoted government officials as saying last year that – until Jordan ends its criticism of Israel’s actions in Gaza – it would no longer send Jordan 100 million cubic metres of water a year, as it has been doing since 2021.
Instead, media reports said Israel had decided to send just the 50 million cubic metres required by the 1994 Israel-Jordan peace agreement.
That makes the desalination project all the more urgent, Motasem Saidan, a former water minister who pushed it forward, told Climate Home News.
“Relying on neighbouring countries for sources of the most important resource for life is risky. You need to have self-sufficiency and water security,” Saidan added.
Largest single GCF investment
French multinationals Meridiam and Suez have been awarded the contract to lead construction of the desalination facility, which Suez says will be one of the largest of its kind globally.
Scheduled for completion in 2030, it will turn 300 million cubic metres of seawater a year – enough to fill 120,000 Olympic-sized swimming pools – into drinking water, which will then be carried by pipeline more than 400 km across the desert to reservoirs near Amman, home to nearly half of Jordan’s population.
The GCF will support it with a $220 million loan and a $75 million grant. While that represents a small share of the total cost, Duarte said last year it represented “the largest single investment in one project that we have made”.
But the GCF’s decision to pour millions into the project followed strong criticism from climate campaigners, initial opposition from some of the fund’s board members and a warning by its independent technical advisory panel (ITAP) over its potential impact on emissions.
The emissions it aims to avoid rest on the timely completion of a 65-km transmission line connecting the desalination plant to the solar farm. Without this, the plant will run entirely on Jordan’s gas-dominated grid, the ITAP said in its assessment report.
Moreover, while the government plans to make the power supplied by the national grid greener in the years ahead, there is no guarantee this will be achieved, the report added.
Such issues make the project “difficult to reconcile with climate finance objectives”, the ITAP said, adding there is a significant risk that “concessional resources could end up subsidising a high-carbon, high-cost water pathway”.
Still, the ITAP concluded that “given the dire water situation in Jordan”, the project’s benefits outweighed those concerns and recommended approval to the board.
Bigger renewables role deemed unfeasible
The possibility of producing more of the plant’s electricity from solar power and batteries was dismissed by the project’s proposer and co-funder – the World Bank’s International Finance Corporation (IFC) – and the GCF as too expensive and impractical, a decision critics see as a wasted opportunity to shift to clean energy.
The companies that carried out the project’s environmental and social impact assessment – Eco Consult and Energies Group – said the option of sourcing all power from renewables “was not studied in detail” because it was seen as unfeasible.
Asked to comment, the GCF spokesperson said the fund supported that conclusion, citing renewable energy’s intermittency and noting that excess solar power produced would be wasted because there is no provision for it to be sold to the grid.
“The optimum design of such a critical life-line desalination project for Jordan is fundamentally a whole-of-system water optimisation challenge rather than a standalone energy storage exercise,” the spokesperson said.
Instead, the plan’s advocates have touted potential emissions reductions as the pipeline replaces water trucks. They say the solar farm set to supply more than a quarter of the desalination plant’s power will prevent 6.7 million tonnes of CO2-equivalent being emitted over its 26-year projected lifetime.
Saidan, the former water minister, said the urgency of providing water must take priority over gas dependency concerns.
“This is not the time to raise such issues,” he told Climate Home News.
But Kostanta Rangelova, a global electricity analyst at think-tank Ember, said the plant could “easily” get at least 80% of its power from solar with batteries, pointing to Jordan’s abundant sunshine and the plunging costs of the equipment needed.
Such systems are set to power large facilities elsewhere in the region, like a luxury Red Sea resort just over the Saudi border and a data centre near Abu Dhabi, she said. Jordan’s own energy sector strategy, published in May, lists increasing battery storage as a strategic target.
Rangelova noted that with battery prices falling significantly in recent years, the cost of solar plus battery storage is now competitive with grid power in many places, particularly in countries like Jordan that have a lot of sun but currently rely on expensive imported gas.
“With solar and batteries, Jordan (could) use homegrown electricity not just during daytime hours, but round-the-clock, which can significantly strengthen its energy security position,” she added.
Lesser of two evils
Using more renewables in the project could also help reduce demand for Israeli natural gas imports – a sensitive issue in Jordan.
“[The desalination plant] will not be viable if we depend on gas supplied by the Israeli occupation,” Mahmoud Amin Al-Hayari, an activist with the General Trade Union of Electricity Workers in Jordan, told Climate Home News.
Jordan’s government is working to develop new sources of gas imports to diversify its current supply, and also wants to boost domestic gas production, alongside renewables.
In the meantime, Jordan’s National Electric Power Company (NEPCO) remains heavily dependent on Israeli gas for electricity generation, industry experts say. Latest government figures from 2024 show the country got 58% of its electric power from gas.
Most of that gas is likely to be Israeli. “About 57% of the electricity that NEPCO supplies to distribution companies comes from gas imported from Israel,” a Jordanian energy and conflict analyst told Climate Home News, asking to speak anonymously due to the sensitivity of the subject.
The spokesperson for Jordan’s Ministry of Water and Irrigation declined to comment on the source of the gas that would help power the Aqaba desalination project.
The issue has gained attention due to several security-related gas supply disruptions from Israel related to the conflict in the Middle East.
For countries like Jordan, a net fuel importer, the energy security case for boosting renewables is a no-brainer, said Ember’s Rangelova. “Unlike imported fossil fuels, the sun cannot be turned off,” she said.
