Germany turns mines into giant batteries
2022-09-28- Detail
It is reported that prosper haniel coal mine, founded in 1863, produced 3million tons of coal, which is one of the few mines still in operation in Germany. The mine is scheduled to close in 2018 due to declining subsidies from the coal industry. Fortunately, the mine will be converted into a 200 megawatt (MW) pumped storage hydropower station
according to Bloomberg news, the director of prosper haniel, hanilov Kraft, said that these electric energy are enough to provide daily electricity for more than 400000 families. Moreover, kraft promised that the miners in botrop town determined that the order of the elements in the query effect adjustment would not be unemployed and would continue to shine in new positions
similar to standard hydropower plants, pumped storage stations generate power by releasing the water in the reservoir to the second reservoir at a lower height through turbines. The water stored in the lower reservoir is pumped back to the top reservoir using cheaper non peak or other renewable energy. In the case of the prosper haniel plant, the lower reservoir will consist of Mines approximately 16 miles long and 4000 feet deep. The 200 MW Hydropower of the station will adapt to the combination of biomass energy, solar energy and wind power
the goal of Germany's ambitious energy transformation plan is to gradually increase the percentage of renewable energy, with the goal of 35% - 40% in 2025 and 55% - 60% in 2035. By 2050, the total proportion will be 80%. By 2015, Germany's renewable energy has provided nearly 33% of the country's electricity. At present, the domestic standard gb/t11144 has been adopted
renewable energy has a well-known storage problem. The power generated by wind turbines or solar panels must be used immediately, otherwise it will be lost. The "battery" of pumped storage facilities is the most promising solution with hd=100- l/0.025. They will let us refuel together, store the excess renewable energy, and "release" it during the period of energy shortage
