Producing water from air is becoming an efficient and sustainable reality due to scientific advancements in the UAE.
Khalifa University is among the leading institutions and companies transforming this concept into practical reality.
It has developed solar-powered water generators that offer a sustainable solution to the Middle East's lack of rain.
To mark World Water Day, a day to underline the importance of fresh and clean water, The National visited the university's projects to find out how they has been progressing.
The technology, powered by solar panels, efficiently extracts water vapour from the air, promising a significant reduction in the cost and environmental impact of traditional water-sourcing methods.
In regions where rain is scarce and importing water costly, this innovation is especially crucial.
With the capacity to produce up to 5,000 litres of water daily, these generators represent a leap towards sustainable water security, aligning with global efforts to find eco-friendly and efficient water solutions.
The Middle East faces severe water scarcity, with per capita availability set to drop below 500 cubic metres annually, indicating absolute scarcity.
By 2050, the region will require an extra 25 billion cubic metres of water yearly, equal to building 65 desalination plants the size of Saudi Arabia's Ras Al Khair plant.
UAE university rises to the challenge
During a tour of one of the solar-powered water generators at Khalifa University’s Sas Al Nakhl campus, Prof Samuel Mao poured a glass of water and took a sip.
“It’s a great solution,” Prof Mao told The National.
He said the university is in the process of preparing a patent application for its unique implementation of water-generation.
Prof Mao, professor of practice in mechanical engineering and a senior director of the Masdar Institute, said that researchers are looking at ways to bring the cost of implementation down, but there’s ample reason for optimism.
Atmospheric water generators, which allow for moisture to be collected from the air, are used around the world but require an energy source, which negates some of the sustainable goals behind them.
Khalifa University’s solution was to use solar panels to power the pars, creating a net-zero solution that could be used especially in the Middle East and North Africa, where the sun is plentiful.
“The technology involves using solar energy to extract water vapour in the air by cooling the air below its dew point,” Prof Mao said.
He said the smaller implementation of the concept at Khalifa University can produce about 50 litres of water a day, but larger implementations could generate up to 5,000 litres daily, without the pollution and waste of conventional desalination processes.
“Water is generated as long as there is sunshine and moisture in air, and the system does not require electric power from the grid,” Prof Mao said.
The quest for sustainable water solutions has led to various innovative approaches worldwide, including at the Cop28 climate conference in Dubai, where water security and harvesting solutions were a focal point.
There, Manhat, a UAE start-up aiming to build floating farms using proprietary technology to generate fresh water from the ocean without electricity, had a booth displaying its devices.
“We want to bring this technology to market as soon as we can,” said Dr Saeed Alkhazraji, Manhat founder, pointing to the company’s devices.
Innovations for a sustainable future
Recent advancements in technology have shown that harvesting water directly from air is not only possible but increasingly efficient, even in the driest of environments.
UK researchers have developed “Solar2Water,” a system that outperforms conventional AWGs by generating twice the amount of water, regardless of ambient humidity levels.
This technology operates with remarkable efficiency, tapping into solar energy to produce clean water in a sustainable and eco-friendly manner.
Researchers at the Massachusetts Institute of Technology have made significant progress with a solar-powered system capable of extracting drinkable water from air with as low as 20 per cent humidity.
This breakthrough is achieved using a two-stage design that uses zeolite, a widely available adsorbent material, to significantly increase the system's water output.
Field tests conducted in the arid conditions of Tempe, Arizona, confirmed the system's potential, marking a substantial step towards providing a sustainable water source for remote, water-scarce regions.
A leap towards sustainable water security
A recent paper in Applied Physics Reviews, an AIP Publishing journal, details another innovation by researchers from Shanghai Jiao Tong University in China: a solar-powered atmospheric water harvesting (AWH) system capable of taking water from the air.
This new technology uses special gels that can soak up and release water from the air very effectively. These gels are made from a mix of materials that work together to pull in water from the surrounding environment.
The study's first author Dr Xiang Chengjie told The National that among all materials that absorb moisture, hygroscopic, or water-attracting, salt is regarded as one of the most effective at drawing in water.
It can capture a lot of water from the air, even when it is not very moist.

While costly, the technology promises competitive drinking water solutions and significant potential for water-stressed regions.
“Although it is not yet possible to solve the problem of low-cost water use in water-stressed regions, we remain optimistic about this technology," Dr Xiang said.

Analysis
Maros Sefcovic is juggling multiple international trade agreement files, but his message was clear when he spoke to The National on Wednesday.
The EU-UAE bilateral trade deal will be finalised soon, he said. It is in everyone’s interests to do so. Both sides want to move quickly and are in alignment. He said the UAE is a very important partner for the EU. It’s full speed ahead - and with some lofty ambitions - on the road to a free trade agreement.
We also talked about US-EU tariffs. He answered that both sides need to talk more and more often, but he is prepared to defend Europe's position and said diplomacy should be a guiding principle through the current moment.

WHAT IS GRAPHENE?
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were experimenting with sticky tape and graphite, the material used as lead in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But when they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment led to graphene being isolated for the very first time.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics.

The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.
