Germany’s Renewable Energy Storage ( Solar Thermal Magazine)
Germany has made the decision in recent years to reduce the amount of nuclear generation to their power grid and to increase the amount of renewable energy available. In fact, net-generation from renewable energy sources in the country has increased from 6.3% in 2000 to about 30% in 2014.
The challenge as a countries percentage of renewable energy increases above 20% is how to handle the intermittent nature of energy from solar and wind sources. Energy storage systems would solve this problem but inexpensive storage systems for electricity have not yet reached commercialization.
If we take a look at Norway we see a power system that comes largely from hydro-electric sources. They also have access to many mountain lakes and water storage areas where they can actually store energy as water at a height. One possibility for Germany to pass the 30% mark for renewable energy is to enlist Norway to store their renewable produced power as pumped storage.
This video explores this possibility.
