One of the reasons why Germans value their success and achievement in clean energy has always been that they will open their minds from time to time to find ways to improve the efficiency and utilization of clean energy.This is not the case that Germany MaxBoglWind companies are The construction of the 'World's Tallest Land Wind Turbine' project is another example of Germans' brainstorming: The project will equip each wind turbine with a bucket of 'water batteries' that will power wind and pumped storage Combining one with one another and double-clicking improve the stability and sustainability of clean energy.
What's more, the 'water battery' is even comparable to the 100 megawatt-hour super battery Tesla CEO Musk has promised to the Australian government!
The concrete pier below the wind turbine tower is the 'water battery'
When the project is on-line in 2018, the four wind turbines will be the world's tallest land-based wind turbine with a height of 178 meters and an overall height of 246.5 meters. As the farther away from the ground, the air flow will be steady, This means higher efficiency, with annual increases of 0.5% to 1% for each additional meter in the height of the cabin, so the height alone is enough to show the Germans' ability.
But this is not the point, with the emphasis on the tank below each tower of the wind turbine.This cement-cast tank not only gives the wind turbine a 'sponge shoe' of up to 40 meters, Increase their power generation, but also become their unique 'water battery'.
The reservoir is a pumped storage part of the storage. MaxBoglWind wind turbine site is very special, just below 200 meters at the top there is a reservoir with its own hydropower station when the grid When sufficient electricity is available, the electricity generated by the wind turbines, even from the grid, can be used to pump water from the reservoir into the water tank, which can be opened when the electricity demand is too high or the wind power is insufficient Brake water is released and kinetic energy is generated by a 200-meter drop.The entire system can be converted from energy storage to electricity generation within 30 seconds, whereas the four storage tanks have a total designed energy storage capacity of 70 MWh. Only 70% of Musk super battery, but this is only 4 wind turbines. If there is 10, 20, 50?
It is important to be able to store excess wind energy in Germany, to be aware that windy Germany often has a negative electricity bill due to excess wind power, and on the weekend of October 29, due to strong winds, Germany's total wind power reached 39,409 MW, the equivalent of 40 nuclear reactors .German Power Grid in order to balance the supply and demand, the excess power consumption so as not to damage the grid, but can only be the electricity costs. Negative electricity means that power plants Must pay the user, or temporarily stop generating electricity.
Germany electricity chart: vertical axis for the euro / MWh, the red line is 0, when the white line is lower than the red line, the electricity bill is negative
At present, the three main technologies of clean energy in the world are solar power generation, wind power generation and hydroelectric power, all of which have their own advantages and disadvantages. By combining wind power generation and hydroelectric power generation, the Germans not only make up the wind power The weakness of the sustainability of power generation, but also make up for the weakness of hydropower limited capacity Let us look forward to the Germans next brain.
