  1. Storage and interconnected renewable energy systems Ingo Stadler

  2. Wind parks in Germany • All technologies for a change to a sustainable energy supply already exist! • How to integrate all the wind (and solar) energy into our grids? • What to do when there is no wind? • What to do when there is too much wind? What are the questions to answer? Source: ISET

  3. Our Electricity Supply System – it‘s a Bone Coal Production Coal Storage Pumped Hydro Coal Transport Natural Gas Production Coal Dump Desulfurization, CO2-Separation Gas Distribution Asse: Ich habe Inkontinenz. Und das bei 24.000 Jahren Halbwertszeit. Das zieht sich.

  7. Potential of Demand Response – only in Germany • Positive control power of all non-electrical storage devices • more than 23 GW in the time range of primary and secondary control power • in all UCTE 3 GW of primary control power is required • good energy balancing capabilities in the range of up to 36 hours • to balance longer deviations additional storage or generation capacity is required. Positive Control Power [GW] Time [h] Ambient Temperature [°C]

  8. Plug in Hybrid • Hybrid Electrical Vehicle (HEV)Capacity ca. 1 kWh • Plug-in Hybrid Electrical Vehicle (PHEV)Capacity 5-10 kWh, el. Driving distance 30-70 km, driving without electricity is possible • Electrical Vehicle (EV)Capacity15-40 kWh, driving distance 100-300 km Quelle: D. U. Sauer Alternatives? Oil, Biofuels, Hydrogen (h=25-35%)
