Energy Storage for the Age of Renewables: Prof. Dr. Eduard R. Heindl at TEDxStuttgart

The next few decades will herald a global change in energy production. The age of renewables requires more than just photovoltaics and windmills: it needs storage systems in an unprecedented volume. However, conventional techniques of storage fail due to the high investments or the low efficiency. This appears to be a stumbling block for the desired change to renewable energy.

His proposed hydraulic hydro storage system gives us a chance to store thousands of GWh at low cost and low environmental impact. The simple yet riveting idea is to lift a rock the size of a soccer stadium using established technologies thereby storing energy. Due to the fact that underground rocks are practically unlimited, the global change to solar power can continue.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
