Energy Storage

Management and storage of heat, mechanical, and electrical energy.
Market, research, and application aspects (eg. Smart-grid, off-grid, Ragone plot, buffer concepts). Thermal energy storage, heat reservoirs, phase transition utilization and chemically bound heat (eg. A district heating network solfanget heat). Mechanical energy storage: Spin Wheels, pumps, turbines and heat recovery (eg. Air compression pump power, spin wheels in various sizes.). Electrochemical storage of electrical energy: Important battery technologies and hydrogen technologies (excl. Lead batteries, various Li-ion batteries, unlike electrolysis of water, different hydrogen storage, and various fuel cells).
System evaluation and modeling: Usage of LabView to set up different energy storage units in laboratory use.
