In the middle of the Dubai desert, people are about to complete the huge solar park that can shove everything


After eight years of construction, satellite images have partly shown the scale of the Mohammed Bin Rashid Al Maktoum Solar Park: the kilometer of photovoltaic panels arranged along the western east, their uniformity contrary to the folds of sand layers around the power plant. After completion, the Dubai Department of Energy & Water (DEWA) confirmed that this 50 billion dirham investment (about US $ 13.6 million) could supply energy to 1.3 million homes, minimizing about 6.5 tons of carbon emissions per year.

First published in 2012 and expected to be completed by 2030, this 5,000 megawatt park will have a construction time three times longer than the famous Buri Khalifa building. Phase 1 and 2 were completed, with 2.3 million photovoltaic panels with 213 megawatt capacity. Phase 3 is underway, adding 3 million photovoltaic panels and an additional 800 megawatts of capacity, to be completed by 2020.

After many years across the desert, this energy project is about to enter phase 4 – perhaps the most ambitious development ever. DEWA claims, it will have the world's tallest Solar Absorption Tower (CSP). It will use mirrors called sun glasses to focus the sun on the top of the tower to melt salt. The heat generated will run steam turbines, producing electricity.

Solar power generation system is located in California.

"Normally, CSP will have a slightly higher performance than photovoltaic"Christos Markides, a professor of clean energy technology at Imperial College London, told CNN."CSP stores energy in the form of heat rather than in batteries. Storage of thermal energy is 10 times cheaper than storing electrical energy, "he explained." This gives the advantage of that special technology."

In fact, that means that CSP can continue to generate electricity even without the Sun and at night. Dubai's energy tower can store heat for 15 hours and provide energy 24 hours a day. The CSP tower is 260 meters high when completed and will be surrounded by 70,000 regular glass.

Besides the 100 megawatt solar power tower, Phase 4 will supply 850 megawatts of electricity through parabolic troughs (another type of solar tower) and photovoltaic. And according to a recent announcement, Phase 5 with 900 megawatts of photovoltaic capacity will start in 2021, while doing other tasks that will help the park reach its final goal of 5,000 megawatts in the right way. plan.

With a capacity of 1,963 megawatts, Mohammed Bin Rashid Al Maktoum Solar Park has named itself on the list of the most powerful solar parks in the world. According to the World Economic Forum, another building in India – Ladakh 3,000 megawatt solar farm will go into operation in 2023. Currently, the desert solar park has a capacity of 1,547 megawatt in Ningxia, China is considered the world's largest active photovoltaic park.

However, building this huge scale is only part of the story. Resilience to weather conditions and the devastation of time are also core issues.

DEWA said: "Dust is really a big challenge, because dust on the modules can reduce their ability to generate energy. " Along with researching the technology of coating photovoltaic panels, the government also implemented "Cleaning robot system to make factory books in short time."

Markides affirms the importance of temperature: "Photovoltaic panels will deteriorate faster if large temperature fluctuations occur, such as being very cold and very hot, or when the temperature becomes extremely hot"In Dubai, temperatures can shift from 40 degrees Celsius in the day to frosty nights.

Dubai 2050's clean energy strategy is aiming to create 25% of energy from clean sources by 2030 and 75% by 2050 – equivalent to a capacity of 42,000 megawatts.
