How solar-powered desalination allows Saudi Arabia to produce potable water sustainably

  • Desalination of seawater allows parched Gulf nations to access plentiful water for farming and human consumption
  • To cut emissions, the Kingdom is adopting renewable energy sources to power its filtration and treatment plants

RIYADH: In regions with limited rainfall, desalination is a practical means of sourcing plentiful water for farming and human consumption. However, the process of turning seawater into freshwater is notoriously energy intensive.

Indeed, desalination is a significant contributor to carbon emissions in the water-scarce Arabian Peninsula. That is why Saudi Arabia has been investing in green energy sources to power its desalination plants.

“Using renewable energies for desalination is crucial as it contributes to reducing the operation’s carbon footprint and water production costs,” Sultan Al-Rajhi, spokesperson for the Saudi Water Authority, told Arab News.

 

 

Due to the scarcity of freshwater resources in a region with a rapidly growing population, seawater desalination is essential to keep pace with demand, he added.

“Saudi Arabia depends on desalination of seawater due to the nature of the desert climate, in which the presence of surface water and natural rivers is rare,” Al-Rajhi said.

In fact, desalination accounts for about 75 percent of the Kingdom’s water supply.

“Therefore, investment is being made in desalination of seawater to meet the demand for population and economic growth witnessed in the Gulf region as a whole.”

Each year, the Kingdom requires an average of 5.5 billion cubic meters of freshwater. The need for water is especially high during the Hajj and Umrah seasons, when well over a million pilgrims arrive from around the world.

Home to more than 37 million people, the Kingdom is the world’s third-largest consumer of water per head of population. Agriculture alone accounts for around 84 percent of total water consumption.

Desalination is a complex process that involves removing salt and other impurities from seawater. Since the process requires a significant amount of energy, adopting renewables such as solar to power these facilities has become a top priority.

“To develop climate-resilient infrastructure for sustainable desalination, Saudi Arabia should prioritize innovative and renewable technologies,” Abdulaziz Daghestani, area sales director of water utilities and country director at Grundfos, told Arab News.

Grundfos is a Danish company that is working with regional states to provide innovative pumping solutions for water supply, wastewater management, heating and cooling, and industrial processes. 

According to Daghestani, integrating advanced monitoring systems can help optimize desalination operations and enhance efficiency.

“Using real-time data and analytics, we can improve water management practices and make timely adjustments to meet the varying increasing demand for human consumption and agriculture,” he said.

The Qatrah program, which means “droplet” in Arabic, was launched by the Ministry of Environment, Water, and Agriculture in 2020, and aims to reduce excess water usage by eliminating waste, and encouraging the conservation and reuse of existing freshwater.

Its objective is to lower daily per-capita water consumption from 263 liters to 150 liters by 2030. To do this, the ministry has created a unified framework, known as the National Water Strategy, for the country.

However, despite these efforts to improve the sustainability of water systems, desalination remains a crucial means of meeting water demand, making the adoption of clean energy sources and efficient production techniques a critical priority.

DID YOUKNOW?

• In 2023, Saudi Arabia had a desalination capacity of 13.2m cubic meters per day.

• 7 million cubic meters of desalinated water have been generated by the Al-Khafji plant.

• Desalination accounts for 60 percent of the urban water supply in Saudi Arabia.

• Agriculture makes up 84 percent of the Kingdom’s water needs.

Al-Khafji Desalination Plant, located in the Kingdom’s Eastern Province, is the world’s largest solar-powered water desalination project, providing the region’s water requirements through an innovative and environmentally friendly approach.

The plant can generate up to 90,000 cubic meters of freshwater per day using innovative technology created by the King Abdulaziz City for Science and Technology. 

Its new Solar Saline Water Reverse Osmosis method uses a process known as ultra-filtration during the pre-treatment phase.

The method involves forcing seawater through a semipermeable membrane that only allows water molecules to pass, while blocking the salt and other contaminants. The resulting purified water is then collected for distribution.

Since its launch in 2018, more than 7 million cubic meters of freshwater produced by the plant have already been utilized.

“Using reverse osmosis technology is considered to have the lowest rates of carbon emissions as a result of the increase in energy efficiency through the development of this field in recent years,” said Al-Rajhi.

“The rate of carbon emissions per cubic meter in some desalination systems has been reduced to 91 percent compared with thermal desalination systems.”

Solar is not the only source of renewable energy that can be adopted to power the desalination process.

“This is in addition to the prospective use of hydraulic turbines to convert the kinetic energy resulting from the flow of water into electricity to generate clean energy,” said Al-Rajhi.

This shift toward renewables not only addresses the high energy costs associated with desalination but also supports Saudi Arabia’s commitment to sustainable development. 

Inger Andersen, executive director of the UN Environment Programme, has praised the Kingdom’s water conservation agenda, which is part and parcel with its environmental mission, the Saudi Green Initiative.

Saudi Arabia is correct to prioritize “not over-extracting and being very wise around environmental management.”

“That is why we are quite impressed by the Saudi Green Initiative,” she told Arab News.

This transition to cleaner energy sources reflects a strategic decision to enhance the Kingdom’s energy efficiency and reduce its dependence on fossil fuels, while simultaneously addressing the challenges posed by climate change.

Integrating renewable energy into desalination processes marks a significant step toward achieving a more sustainable and environmentally-conscious approach to water production.

Hosted at Bait Amir Bahar in Al-Balad, one of Jeddah’s historic homes, the exhibition highlights both the similarities and contrasts between the artistic styles while showcasing the cultural depth of Japanese storytelling.

Rather than simply focusing on how Hokusai’s work influenced manga, the exhibition invites visitors to compare both styles and understand what makes them unique. It examines themes such as visual storytelling, artistic techniques and cultural participation across different eras.

HIGHLIGHT

The exhibition in Jeddah explores the evolution of Japanese manga from the 19th-century works of ukiyo-e master Katsushika Hokusai to the modern format that has gained widespread popularity in the Kingdom.

Hokusai’s manga drawings, while sometimes resembling cartoons, encompass a wide variety of subjects, from nature to human expressions and everyday life. Unlike modern comics, his work was not centered on humor but balanced artistic instruction with entertainment — much like how manga today combines storytelling with visual artistry.

Hokusai created his manga using woodblock printing, transferring the images onto paper in three primary colors: Black, gray and pale peach. The collection, comprising 4,000 illustrations across almost 800 pages, was published between 1814 and 1878 in 15 volumes bound with string.

The phrase denshin kaishu, which precedes the title, translates to “transmitting the spirit and learning the craft,” highlighting the collection’s educational purpose.

Hokusai Manga was originally used as a reference book for aspiring artists, much like today’s “How to Draw Manga” guides. Similar to modern fan-made manga, his work encouraged learning, copying and artistic experimentation.

In an exclusive interview with Arab News, Daisuke Yamamoto, the consul-general of Japan in Jeddah, described Hokusai as one of Japan’s greatest artists, modernizing traditional print styles through innovations in subject matter and composition.

“Hokusai transformed the ukiyo-e genre traditionally focused on images of fleeting pleasures — by shifting its emphasis from people to landscapes and the changing seasons,” Yamamoto said. “His print designs invited audiences to witness nature’s transience, capturing birds in flight, flowers in bloom and water in motion. Through his work, he blended an acute awareness of the fleeting with a deep appreciation for the timeless.”

According to an official statement, Hokusai’s work captured Japan’s diverse landscapes, portraying scenes and activities connected by shared symbols and narratives. He was among the first artists to both shape and be shaped by globalization, drawing from international influences and later inspiring European artists who adopted his decorative motifs, serialized compositions and vision of contemporary society. To this day, countless artists continue to engage with his legacy.

(This exhibition) provides an opportunity for a wide range of people to know about each other’s culture, which will be reflected in the future in their understanding of each other and facilitate all other aspects of cooperation.

Since the 1970s, Hokusai himself has appeared as a character in manga, reimagined by various artists in styles ranging from realistic portrayals to fantastical interpretations. This reflects manga’s evolution, blending historical figures with contemporary storytelling techniques.

Ukiyo-e, the popular art of the 18th and 19th centuries, foreshadowed comic techniques such as visualizing the invisible. However, its speech-like balloons often depicted dreams rather than dialogue, and weather lines were integrated into the scene rather than used as abstract symbols.

Hokusai’s most popular collection of printed drawings was named “manga.” While the collection is primarily known for its diverse subjects and painting style, its frequent portrayal of exaggerated expressions and acrobatic scenes has led many to associate “manga” with cartoons or humorous images.

When compared to the work of his contemporary, Utagawa Kuniyoshi, it becomes clear that Hokusai’s manga images were not necessarily intended to be funny.

In 19th-century Japan, the success of Hokusai’s manga was rooted in the balance between the mundane and the whimsical, instruction and entertainment. This blend helped secure the collection’s lasting appeal.

Today’s Japanese comics share similarities in content, particularly in their focus on capturing movement, and in their wide circulation, thanks to advancements in reproduction technology.
