Energy Storage 2

• Management and storage of heat, mechanical, and electrical energy.
• 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, solar heat).
• Mechanical energy storage: flywheel, pumps, turbines and heat recovery (eg air compression pump power, flywheels of various sizes).
• Electrochemical storage of electrical energy: important battery technologies and hydrogen technologies (incl. Lead-acid batteries, various Li-ion batteries, various technologies for electrolysis of water, different hydrogen storage technologies, and various fuel cells).

• Knowledge : The candidate must understand - Concept and operation of available and relevant energy storage systems. - Comparison tools used in system evaluation. - Different needs within energy storage. - Cause and propagation of efficiency losses in various energy storage systems. - Manufacturing, testing and ageing of Li-ion batteries, fuel cells and electrolysis cells.
• Skills: The candidate is expected to be able to - explain the concept and operation of available and relevant energy storage systems. - calculate the efficiency of charging cycles for different energy storage systems. - design energy and power needs of simple hybrid systems based on output and energy capacity.
• General competence : The candidate is expected to manage basic principles for accessible and relevant energy storage systems and quantitatively and qualitatively be able to compare these. - The candidate knows how to produce and test Li-ion battery cells, fuel cells and electrolysis cells.

Compulsory lectures, compulsory tutorials, and compulsory laboratory exercises.
