David Gögelein, a PhD student from the University of Applied Sciences in Ulm, presents on storage systems and sector coupling. He begins by defining energy storage as processes involving charging, storing, and discharging energy—highlighting its ability to store energy for later use. This is crucial because renewable energy sources like wind and solar are inconsistent due to environmental factors but must meet everyday demands. Gögelein discusses key characteristics of energy storages: capacity (limited amount they can store), power capability (rate of charge/discharge), efficiency (losses during these processes), self-discharge rate (standby losses over time), and cost-effectiveness. For households, batteries such as lithium iron phosphate or lead-acid are commonly used despite varying efficiencies and costs. To optimize household storage capabilities without solely relying on electrical storages, combining different technologies—like integrating thermal storage in water heaters—is proposed. Thermal storages offer rapid heating yet suffer higher standby losses compared to battery technologies. The presentation emphasizes adapting technology combinations to enhance overall household energy management effectively.

While solar modules are getting cheaper, storage is the key factor that determines the cost of the system. Besides new battery technologies, other forms of storage are available.
