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.

What drives subscription retailing?
Once the domain of newspaper home deliveries, subscription model retailing has combined with e-commerce to permeate myriad products and services.
The concept has grown tremendously around the world and is forecast to thrive further, according to UnivDatos Market Insights’ report on recent and predicted trends in the sector.
The global subscription e-commerce market was valued at $13.2 billion (Dh48.5bn) in 2018. It is forecast to touch $478.2bn in 2025, and include the entertainment, fitness, food, cosmetics, baby care and fashion sectors.
The report says subscription-based services currently constitute “a small trend within e-commerce”. The US hosts almost 70 per cent of recurring plan firms, including leaders Dollar Shave Club, Hello Fresh and Netflix. Walmart and Sephora are among longer established retailers entering the space.
UnivDatos cites younger and affluent urbanites as prime subscription targets, with women currently the largest share of end-users.
That’s expected to remain unchanged until 2025, when women will represent a $246.6bn market share, owing to increasing numbers of start-ups targeting women.
Personal care and beauty occupy the largest chunk of the worldwide subscription e-commerce market, with changing lifestyles, work schedules, customisation and convenience among the chief future drivers.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”
