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

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.

  • The West African country celebrates its independence yearly on April 4th, the day it signed a transfer of power agreement with France in 1960 to form the Mali Federation with French Sudan

JEDDAH: Saudi Arabia's King Salman and Crown Prince Mohammed bin Salman on Friday congratulated Senegal's President Bassirou Diomaye Faye on his country's Independence Day.

In a cable, King Salman wished the Faye "continued good health and happiness", and the government and people of Senegal "steady progress and prosperity."

The crown prince issued a similar statement, the Saudi Press Agency reported.

The West African country celebrates its independence yearly on April 4th, the day it signed a transfer of power agreement with France in 1960 to form the Mali Federation with French Sudan. The union, however, was short-lived as the two dissolved their union in August of the same year and the former French Sudan became the Republic of Mali.

In early 1982, Senegal and neighboring Gambia formed the Confederation of Senegambia, but parted ways in 1989 as the integration was never carried out.

Faye, the current president, was an opposition candidate who rose to power after defeating incumbent president Macky Sall in the March 2024 election.

Sergey Smbatyan, founder of the Armenian State Symphony Orchestra and the artistic director and principal conductor since 2005, was on hand to lend context and commentary between the scores on opening night.

He told the crowd before the show: “If you’re not a gamer, what I want you to do is to imagine that you’re in a museum — an art museum — but instead of a curator telling you about the images that you’re going to see on this huge screen, let these musicians tell you that exact story.

“Tonight there is no right time to clap; there is no wrong time to clap. If you hear something you like from these guys (gesturing to the orchestra behind him on stage), let us know.

“We're going to start off tonight with role-play games, or what are known as RPGs, where players assume the roles of characters in a fictional setting. The game is focused on interactive storytelling, decision-making and strategy.”

Dhahran resident Paul Blay took his two daughters Sylvia, 11, and Celeste, 10, to the show.

Blay, who is a father of six, told Arab News: “I get emails about Ithra events and saw this one and I thought it would be fun for me and the girls to go to. Like with anyone that you love, I shared the things I love with them.”

The Blay family moved to the Kingdom last year and were keen to attend an event that merged gaming with music.

Celeste told Arab News: “I really like video game music; the music is really pretty and I like listening to that. It is kind of what motivated me to come here. And, also, my dad likes video games.”

The older Blay sisters have both taken music lessons and play multiple instruments, including the piano, the harp and the clarinet.

Their father said: “Some of the best music that’s being composed nowadays is for movies and video games. I expected it to be really high quality and good (at Ithra).”

The event featured music from Guild Wars 2, World of Warcraft, The Witcher 3 and Assassin’s Creed 2, among many others.

The last show takes place on April 5, with tickets starting at SR200 ($53), available at the venue or via the Ithra website.
