Where (grid-level) could this systems be located ?
► central electric storages
- pumped hydro
- hydrogen generation
- compressed air energy storage
► decentralized huge batteries
- lead acid batteries
- NaS batteries
- Redox-Flow batteries
► local batteries
- lithium-ion batteries
- lead acid batteries
- NiMh-, NiCd batteries
► virtual storages
- HP + thermal storage
- µCHP + thermal storage
Dr. Christian Doetsch, Fraunhofer UMSICHT
2012-Sep-13 Berlin, Jahrestagung 2012, Chart 8
Basic technical framework
► there is always a real grid no ideal grid
- fluctuations are local (e.g. PV) or central (e.g. wind)
- demand fluctuations are local (household) or central (industry)
- storages, DSM etc. are always local or central options
► Germany was, is and will be no island
- grid connections to European neighbors
- embedded to the European grid
- important for 100% renewable energy scenario

Vision » hybrid urban energy storage «
Realization of high shares of renewable energies by a smart combination of different storages:
Few huge centralized storages, some big decentralized storages and many small decentralized
storages and virtual storages (incl. thermal storages) mostly located in the city.

Conclusions ► energy balancing demand will increase due to
higher penetration of fluctuating renewable energies
► different storage technologies will be located at different
points of the grid and will solve different problems
► Germany has a good but no ideal grid (restrictions)
but is embedded in the European grid
► energy balancing demand ≠ energy storage demand
► many different measurements for grid balancing,
virtual (e.g. DSM) and real storages must be
aggregated and operated in a coordinated way
► economical regulations must support these
operations modes
