04 Feb Huge battery of 108MW online in UAE
The United Arab Emirates (UAE) want to get a lot of energy from renewable sources in the coming years. The largest battery in the world should help with this, with a capacity of more than 100 megawatts. This reports tech website Quartz.
In the United Arab Emirates (UAE) there is no lack of sun; solar panels function great. If the sun is not shining, batteries offer a solution. They are installed at ten locations in the country, but are controlled from one location. As a result, they operate as one large “virtual” power plant, with a capacity of 108 megawatts. The batteries must provide 649 megawatt hours of energy. The storage capacity of the battery is many times greater than that of the battery system that Tesla installed in Australia in 2017. That system has a capacity of 100 megawatt hours. With the Australian battery, Tesla then had the largest storage battery in the world.
The emirates have a large oil industry but want to invest billions of dollars in renewable energy in the coming years. For that purpose, $ 163 billion has already been released in 2017. In 2050 the government wants to get more than sixty percent of the energy from renewable sources. Because many inhabitants live on the coast, climate change can have far-reaching consequences. Abu Dhabi is also building a solar park that should become the largest in the world. The park cost $ 872 million in 2016 and should have a capacity of 1,177 megawatts.
Sodium sulfur batteries
The battery system currently used by the UAE consists of sodium-sulfur batteries supplied by a Japanese company. Lithium-ion batteries used in electric cars, for example, are smaller than sodium-sulfur batteries, but need air conditioning to operate at the right temperature. The sodium-sulfur batteries work at a temperature of 300 degrees Celsius and are therefore suitable for the high temperatures in the desert. The batteries themselves are well insulated; a cooling battery can cause serious damage. According to Quartz, the capacity of 108 megawatts is sufficient to provide Abu Dhabi with energy for six hours in an emergency.
