Seminar “Stationary energy storage and its economics: Examples in German or European Market.”
by Prof. Dr. Dirk Uwe Sauer, RWTH Aachen University
Renewable energies and especially photovoltaics are by far the fastest growing power generation technology. For a stable grid operation, the intermittence of the renewables is a challenge. But due to the strong decrease of battery prices, energy storage capacity can be added to the system today at acceptable costs, high speed and high flexibility regarding the location.
The seminar will give a deep insight into the technology and a possible design of the power market to foster the integration of battery storage systems.
- Part 1 (9 am to 12:30 am): Technologies for stationary battery storage systems
- Performance, lifetime, safety and cost of lithium-based battery technologies
- Performance, lifetime and cost of sodium-ion battery technologies
- Overview on other battery technologies with respect to their potential for the stationary energy market in the coming years
- Container-based systems for > 5 MWh storage systems
- Battery home applications
- Vehicle-to-grid services
- Part 2 (1:30 pm to 5 pm): Markets and market design for energy storage systems in the power grid
- Market growth of stationary storage systems in China and Europe
- Cost structure of stationary storage systems
- Interactive cost calculation for installed power and energy capacity, and per kWh energy sale
- Detailed look into design and market for different service and revenue potential of stationary energy storage systems in “behind-the-meter applications” and “front-of-the-meter applications” based on the example of the German energy market
