Saudi Neom megacity will have world’s first ‘solar dome’ desalination plant

  • Facility will be completely sustainable, carbon neutral and greatly reduce environmental impact of water extraction
  • Construction is due to begin in the next month and is expected to be complete by end of 2020

TABUK: The Neom smart-city project will use cutting-edge solar technology to power a desalination plant that produces clean, low-cost, environmentally friendly fresh water.

The decision aims to enhance megacity’s position as a new global tourism destination, a center of innovation and environmental conservation, and as an accelerator of human progress.

Neom signed an agreement with UK business Solar Water Limited to build a desalination plant in the northwest of the Kingdom that uses the newly developed “solar dome” technology. It is hoped the first-of-its-kind, completely sustainable and carbon-neutral facility will shape the future of desalination in Neom, the Kingdom and throughout the world.

Work on the solar dome project will begin in February and is expected to be completed by the end of the year. The technology it employs will significantly reduce the environmental impact of the desalination process by producing less saline solution, a byproduct that can harm natural ecosystems.

The pioneering and innovative approach from Solar Water Limited, which was developed at Cranfield University in the UK, represents the first widespread use of concentrated solar power technology in desalination, Neom said. Seawater is pumped into a hydrological solar dome made of glass and steel, where it is heated and evaporated to remove the salt. The process can continue at night thanks to the storage of solar energy generated throughout the day. The technology helps to prevent any damage to marine life as it does not dump saline solution created by the process back into the sea.

“Neom’s adoption of the experimental version of this program supports the sustainability goals set by the Ministry in the Kingdom, as shown in the National Water Strategy 2030, and is fully in line with the sustainable-development goals set by the United Nations,” said Minister of Environment, Water and Agriculture Abdulrahman Al-Fadhli.

Neom CEO Nadhmi Al-Nasr said that the megacity project has easy access to abundant amounts of seawater and completely renewable energy resources, which puts it in the ideal position to produce low-cost and sustainable fresh water using solar-powered desalination.

He added that the adoption of this type of technology reflects Neom’s commitment to supporting innovation, protecting the environment and preserving its purity to provide a comfortable and exceptional life. It also raises the possibility of using the technology in other parts of Saudi Arabia in cooperation with the Ministry of Environment, Water and Agriculture.

David Reavley, the CEO of Solar Water Ltd, said: “Currently, thousands of desalination plants around the world rely heavily on burning fossil fuels for water extraction, and we have the technology to desalinate water in a way that is completely sustainable and 100 percent carbon neutral.

“We are happy to partner with Neom, which has a strong vision of what the new future looks like in harmony and integration with nature.”

World’s first International Conference on Conjoined Twins kicks off in Riyadh

  • Top World Health Organization official commends Saudi Arabia’s efforts in the field

RIYADH: The inaugural International Conference on Conjoined Twins kicked off in Riyadh on Sunday. 

The event unites leading medical experts, humanitarian organizations, and families from around the globe to share vital insights, discuss innovative separation techniques, and forge collaborative pathways in the pursuit of improved lives for conjoined twins. 

Riyadh Gov. Prince Faisal bin Bandar delivered a speech on behalf of King Salman celebrating the achievements of the Saudi Conjoined Twins Program, which has become a global leader in the field.

“Since 1990, 143 cases of twins from 26 countries have been reviewed by my dear colleagues, who have successfully separated a total of 61 pairs of twins to date,” he said. 

Prince Faisal added that it is the only program globally specializing in separating conjoined twins, making it one of the largest humanitarian medical programs in the world. 

He also highlighted a recent milestone: the UN General Assembly is considering an initiative by Saudi Arabia to designate Nov. 24 as the annual World Conjoined Twins Day.

In a video address, Dr. Tedros Adhanom Ghebreyesus, director general of the World Health Organization, congratulated Saudi Arabia on its leadership in organizing the conference.

“I commend Saudi Arabia for its leadership in organizing this important World Conjoined Twins Day Conference,” he said. 

This recognition would honor the medical and humanitarian efforts in this field and highlight the challenges faced by conjoined twins and their families. 

Ghebreyesus praised the initiative as a model for global collaboration in rare and complex medical cases. 

“The conference provides critical insights, from surgical innovations to long-term strategies, shaping rare initiatives. A broader platform and registry for congenital anomalies would benefit low and middle-income countries,” he said.

A keynote address was delivered by Dr. Abdullah Al-Rabeeah, advisor to the Royal Court and supervisor-general of Saudi aid agency KSrelief.

As the head of the multidisciplinary team for the Saudi Conjoined Twins Program, Al-Rabeeah provided insights into the occurrence and challenges associated with conjoined twins.

The history of conjoined twin separation reveals both the challenges and progress in medical science. 

“The first successful separation was by Johannes Fatio back in 1689 by using a constricting band for a set of Omphalopagus twins or those sharing liver and gastrointestinal organs,” he said.

With a 0.5 percent incidence rate, this early success involved “presumably, a small joining in the skin, probably a little bit of the liver,” said Al-Rabeeah. 

He added that a major breakthrough came in 1957 with the first successful separation of Craniopagus, or twins sharing one brain. 

Al-Rabeeah said that the epidemiology shows distinct patterns: “In Western countries, it’s been estimated that we get one conjoined twins in every 50 to 200,000 births.” 

He added that, however, it is more prevalent in Southeast Asia and Africa, “presumably because identical twinning and twinning is (found) more in dark-skinned people in Africa and also in Southeast Asia, increasing the incidence.”

The survival statistics, Al-Rabeeah reported, entail that “60 percent of conjoined twins are stillborn, and those who live 40 percent of them will die in the first few days of life, and 70 percent of those who would survive will be females.”

He emphasized that the reasons behind this regional disparity remain unknown and require further research.

Throughout the conference, leading medical professionals presented their expertise on various aspects of caring for and separating conjoined twins. Topics included embryology, multidisciplinary team-building, antenatal care, and labor management. 

Dr. Nadia Al-Ghilan, from the maternal-fetal medicine department at King Abdulaziz Medical City, gave a presentation titled “Caring for Conjoined Twins: A Prenatal Journey,” describing the complex process of managing pregnancies involving conjoined twins.  

She said that caring for conjoined twins is a complex and delicate process as it requires meticulous prenatal planning and a dedicated medical team.

Al-Ghilan said that “this journey is filled with unique challenges, ethical considerations, and the utmost care to ensure the best possible outcomes for the twins and their family.” 

Early diagnosis, she stressed, is critical for effective prenatal referral, counseling, and planning for delivery and postnatal care.  

Al-Ghilan also underscored the importance of genetic testing in understanding the chromosomal health of conjoined twins. 

“Techniques like amniocentesis and chorionic villus sampling can help identify genetic abnormalities, providing valuable information for developing treatment strategies.”

The conference not only serves as a platform for scientific exchange but also fosters dialogue on building global partnerships to support conjoined twins and their families, particularly in low and middle income countries. The conference emphasized the importance of comprehensive care, from prenatal counseling to post-separation rehabilitation. 

For over 30 years, the Saudi Conjoined Twins Program has stood as a beacon of hope for families worldwide. The inaugural International Conference on Conjoined Twins is set to continue this legacy, inspiring further advancements in the care and treatment of conjoined twins globally.

Doctor describes difficulties in separating twins joined at the skull

  • “Conjoined twins are rare, as has been said, but ‘cranomalies’ are extremely rare,” Dr. Felice D’Arco said

RIYADH: A London-based medical expert at a conference in Riyadh revealed the difficulties in separating a rare form of conjoined twins in which the patients are joined at the skull.

Dr. Felice D’Arco, consultant pediatric neurologist at Great Ormond Street Hospital in London, spoke during the International Conference on Conjoined Twins on Sunday about the condition, which occurs in about one of every 2.5 million births worldwide.

“Conjoined twins are rare, as has been said, but ‘cranomalies’ are extremely rare,” he said.

For radiologists, this means there are no standardized CT and MRI scanning protocols in place for such complex cases, and very few recent cases from which to learn.

“We have protocols for everything, epilepsy, tumors, neurogenetic disorders, this is not the case for craniopagus twins because of their rarity,” D’Arco said.

Medical teams must be set in place, and there must be two of everything; two anesthetic teams, two sets of MRI monitoring, etc., the whole hospital staff is involved in what is considered as an operation taking place on two patients simultaneously, D’Arco explained.

While there is a need to standardize procedures, Dr. D’Arco acknowledged that every set of twins is unique.

“As a radiologist, you need to have the flexibility to change your protocol as needed.”

Therefore, he said, it is best to start with a series of questions relating to different critical parts of the body.

One potential issue is the bones. A dual source CT scan can inform radiologists which parts of the skull of each patient is infused, or “missing,” in the other.

Another problem is the relationship between the brains. D’Arco said that small breaches connecting the two brains, identified by 3D sequencing, present a risk that surgery will cause damage.

Considering the possible ethical and medical complications that could come up in cases in which one of the twins is at risk of dying, he said: “Sometimes you need to ask, can we separate without jeopardizing the lives of the children? These cases are complicated, baffling, and confusing.”
