Kombikraftwerk: field test for going 100% renewable
Researchers from the German university of Kassel have linked together several wind, solar, biogas and hydro power plants to explore the possibility of satisfying Germany’s electricity needs only from renewable sources. The problem they are trying to solve is that wind and sun can not be controlled.
If the power from these plants would go into the grid without any precautionary measurements they could take out the whole system. There have to be mechanisms to react to too much or not enough power going into a grid. With the addition of storage through hydro plants and controllable biogas plants, these problems seem to be solved. The researchers say their study shows, that Germany could be powered by 100% of renewable energy.
