water energy Desalination Saudi KSA

  • Another large-scale solar desalination project is currently under construction in Saudi Arabia and scheduled for completion in early 2017. The plant is slated to produce 60,000 cubic meters of water per day for Al Khafji City in North Eastern Saudi Arabia, ensuring a constant water supply to the arid region throughout the year. According to Abengoa, the Spanish renewable energy company building the pioneering facility, the incorporation of solar would significantly reduce operating costs, as Saudi Arabia currently burns 1.5 million barrels of oil per day at its desalination plants, which provide 50-70 percent of its drinking water. Total desalination demand in Saudi Arabia and neighboring countries is expected to reach 110 million cubic meters a day by 2030.

  • Instead of drilling wells or purifying seawater, it will wring moisture from the air to create bottled water at a plant 20 kilometres (12 miles) from Dubai
  • Zero Mass Water, will use renewable energy instead of the fossil fuels that power the many desalination facilities in Dubai and the rest of the United Arab Emirates
  • Zero Mass isn’t going to rival bulk water processors any time soon. It will initially only be able to produce up to 2.3 million litres annually - about the volume of a typical Olympic swimming pool. The technology is still much more expensive than desalination for the same output of water. So Zero Mass’s will be in the same bracket as imported, high-end brands such as Evian and Fiji

  • The bottling plant is run on solar, the bottles we use are recyclable and the caps are sustainable,” said Samiullah Khan, general manager at IBV, an Emirati firm that will buy the water. The caps will be made from bamboo
  • The rectangular boxes - measuring around 2.4 meters (8 feet) by 1.2 meters - absorb water vapour and extract it using solar energy. Although they can operate almost anywhere the sun shines, Dubai’s hot and humid climate makes the emirate a prime location, according to Cody Friesen, founder of Zero Mass
  • The panels have dust filters and use a chemical compound that only captures water molecules, ensuring the water is purified even when the air is polluted.
  • Gulf nations want to reduce their heavy dependence on food imports, especially with the coronavirus pandemic disrupting global supply chains. This month the UAE imported 4,500 dairy cows from Uruguay to boost milk production. It’s also trying to farm rice locally, the success of which will largely depend on using sustainable amounts of water.
  • Water-from-air is only suitable for farming in enclosed environments such as warehouses
  • “With hydroponics, it’s a huge advantage to be using very pure water to begin with,” said Wahlgren. “If you’re using desalinated water, there’s still quite a large salt component, which can be harmful to the plants.”

  • When the $10 billion Red-Dead Canal plan got the axe earlier in August, we discussed plan B for restoring some sense of water security to northern Jordan: a smaller desalination plant in Wadi Araba to trade water with Israel and Palestine. Sure enough, just a couple of weeks later, Jordanian Prime Minister Abdullah Ensour announced that as a matter of strategic national interest, the Kingdom will trade water with Israel. Jordan will sell water produced by a new Red Sea desalination project to their neighbor to the West, in return for which Israel will transfer 50 million cubic meters of water taken from the Tiberian reservoir to the northern section of the Kingdom, which has been especially hard pressed to provide a decent supply of water since hundreds of thousands of refugees have spilled across its borders.
  • Some brine will still be pumped into the Dead Sea, which is problematic since the Red Sea’s sulphate mixed with the Dead Sea’s calcium is expected to leave a film of white gypsum on the water

  • Gazans are spending as much as one-third of their household income on drinking water, and are facing growing health risks
  • Monther Shublaq, the director of Gaza’s Coastal Municipal Water Utilities (CMWU) told The Media Line that Israel has recently raised prices for the water it provides from 75 cents per cubic meter to $1.00 per cubic meter. And while Israel has offered more water, he says, it will not say when it will provide it. “I don’t want it in the winter when I don’t really need it,” Shublaq said. “I want it all year.”
  • Israeli government spokesman Mark Regev says Israel is doing everything possible to help Gazans drink clean water. “Israel has been helping to improve the water infrastructure in Gaza and Israel was willing to double or even triple the amount of water going into Gaza,” Regev told The Media Line. “It is the same water that you and I drink, and the Gazans would pay less than what we pay but they weren’t willing to accept that solution.”

  • 95 percent of the water in the coastal aquifer has dangerous levels of nitrates and chloride, often ten times what the World Health Organization recommends
  • the majority of Gazans now rely on private water deliveries which are not regulated and are often contaminated
  • Palestinians hope to eventually desalinate100 million cubic meters per year to cover most of Gaza’s requirements

  • In Qatar, the country with the highest per capita carbon emissions in the world and the biggest producer of liquid gas, the outdoors is already being air conditioned.
  • The Gulf States are still highly reliant on oil and gas exports, which remain more than 70% of total goods exports in Kuwait, Qatar, Saudi Arabia and Oman, and on oil revenues, which exceed 70% of total government revenues in Kuwait, Qatar, Oman, and Bahrain. In Vision 2030, published in 2016, the Saudi crown prince, Mohammed bin Salman, promised to turn the country into a diversified industrial power house. The reality is very different. The World Bank shows Saudi Arabia is still 75% dependent on oil exports for its budget.
  • The Middle East is warming at twice the rate of the rest of the world. By the end of the century, if the more dire predictions prove true, Mecca may not be habitable, making the summer Haj a pilgrimage of peril, even catastrophe

  • The ruling elites are all dependent on oil rents for the survival of their regimes. They need the oil business to stay alive for them to stay in power. Their system is based on continued oil rent, but ultimately, the citizens’ long-term interests are with a liveable climate
  • The precise point oil demand will peak has been contested, and depends on a myriad of assumptions about regulation, technology and consumer behaviour. But many people say demand will peak in about 2040, and then decline.
  • the International Energy Association’s report Net Zero by 2050, by contrast, proposed oil demand fall from 88m barrels a day (mb/d) in 2020, to 72 mb/d in 2030 and to 24 mb/d in 2050, a fall of almost 75% between 2020 and 2050. It argued that the Gulf has all three elements needed to switch to renewables: capital, sun and large tracts of vacant land.
  • Opec’s own projections suggest oil demand will rise in absolute terms through to 2045, and oil’s share of world wide energy demand will fall only from 30% to 28%. Hardly a green revolution.
  • In the United Arab Emirates it is estimated that the climate crisis costs £6bn a year in higher health costs. The salinity of the Gulf, caused by proliferating desalination plants, has increased by 20%, with all the likely impact on marine life and biodiversity.
  • Aramco, the Saudi company with the largest carbon footprint in the world, is not trying to diversify at the rate of Shell or BP. Indeed, it has just announced an investment to increase crude capacity from 12m barrels a day to 13m barrels by 2027
  • If you see the lifestyle in the UAE, Saudi Arabia and Qatar, it is based on endless consumption
  • The region is responsible for only 4.7 % of worldwide carbon emissions, dwarfed by the pollution from Europe, America and China. The oil that the Middle East exports is logged against the carbon emissions of the users, not the producers.
  • The Gulf’s self-proclaimed first mover, the UAE, was the first country in the region to ratify the Paris agreement and is now the least dependent on oil for government revenues. Last week it announced a “net zero initiative by 2050” to be begun with $163bn (£118bn) of investments and a new minister for climate change and the environment, Mariam Almheiri. The announcement came after the UAE ordered an 80-day brainstorming session in every government department from June. It was the first petro-state to embrace net zero in domestic consumption.
  • Gulf states are deeply competitive, so a flurry of news is emerging. Qatar has appointed a climate minister; Bahrain is targeting net zero by 2050; Kuwait has a new emissions plan.
  • Fossil fuels shipped abroad are not on the Saudi’s carbon ledger, owing to UN accounting rules, and the promised internal reduction in emissions is dependent on a heavy bet that unproven blue hydrogen and carbon capture technology will work.
