With the inevitable depletion of traditional fuel sources, many countries are now spending time, money and effort developing alternative and renewable energy sources, and Dubai seems to be at the forefront. .
Dubai has begun construction of what is likely to be the world's largest solar power plant (CSP), stating ambitiously that it plans to make it operational by the fourth quarter of 2020.
An Arab News report said, "The plant will have an estimated capacity of 700 megawatts and an energy storage system that will keep the lights of Dubai on for up to 15 hours after sunset. The project will include the tallest solar tower in the world, 260 meters, and as high as Emirates Towers in Dubai. The solar power plant will cover 3,750 hectares, the equivalent of 4,500 football fields. The solar park as a whole is expected to produce five gigawatts once completed. Noor Energy 1, as the project calls it, will eclipse the current record holder, Noor-Ouarzazate CSP in Morocco. & # 39;
Abdulhameed Al-Muhaidib, director of asset management at ACWA Power in Saudi Arabia, explained the difference between ordinary solar panels and concentrated solar energy technology:
"It's a completely different technology because you have to exchange heat and use steam turbines, which makes it more expensive than solar PV, and lithium batteries are always expensive." This is because At present, lithium-ion batteries are the only plausible option for storing solar energy.
He further explained that they would not use water to store the heat of the sun, but to store concentrated sunlight in molten salt, thus retaining its heat longer than the sun. 39; water. This will store energy long after sunset, at a lower cost. Once needed, the heated salt will be pumped and used to boil water to produce steam. Once the salt has cooled, it can be recycled and reused.
The city is trying to increase the percentages shared by renewables by 7% by 2020, by 25% by 2030 and by 75% by 2050.
Although concentrated solar energy technology remains largely unknown to the general public, it will soon power one of the most magnificent cities in the world.
